Snorkeling vs. Diving: Which One’s for You?
Bali’s crystal-clear waters hold two doors into the same magical world: snorkeling gives you a glimpse; diving lets you dive right in. But how do you know which is right for you?
Snorkeling is the more accessible option, perfect for beginners or those who want a quick, effortless way to explore the shallows. With just a mask, snorkel, and fins, you can float on the surface while watching the reef life unfold below you. Generally, it’s ideal for calm bays, close-to-shore coral gardens, family-friendly beaches, and anyone short on time. You don’t need certification or experience—just a sense of wonder.
Scuba diving, on the other hand, takes you deeper—both physically and in experience. With full gear, including an oxygen tank and regulator, plus certification requirements, diving is more technical and time-intensive. But the payoff is huge. Divers can explore drop-offs, underwater caves, artificial reefs, and even historic shipwrecks. In deeper waters, you’re more likely to encounter larger marine species like reef sharks, manta rays, and schools of jackfish swirling in choreographed motion.
Regardless which one you prefer to try, both activities share access to Bali’s extraordinary marine biodiversity. But where snorkeling gives you a vibrant surface-level glimpse, diving invites you into the immersive quiet of the deep, where every breath and movement counts. Rule of the thumb is: if you’re looking for a quick and fun ocean adventure with minimal barriers to entry, snorkeling is your go-to. If you’re craving a more immersive, technical, and extended journey into the ocean’s depths, diving offers a richer reward.
Guided Tours vs. DIY Snorkeling: What’s Better?
Once you’ve decided whether you prefer to snorkel or dive, the next step is choosing between a guided experience or going the DIY route. Basically, this choice depends largely on your destination, comfort level in the water, and the type of experience you want.
Guided tours are ideal for travelers who value knowledge, convenience, and added confidence in the water. These tours typically include hotel pick-up, equipment, safety briefings, and multilingual guides who understand the best times and places to spot marine life. A guide can enhance your experience by leading you to high-activity areas, explaining the behaviors of different species, and ensuring your safety throughout the trip. If you’re heading to more challenging spots where conditions may involve strong currents or boat-only access, a guided tour is highly recommended for both safety and peace of mind.
DIY snorkeling, on the other hand, suits independent travelers who prefer a more flexible and budget-friendly approach. If you already have your own gear or plan to explore shore-accessible locations, snorkeling on your own can be a rewarding option. It allows you to set your own pace, choose your schedule, and enjoy a more relaxed experience, especially in quieter areas with calm waters and informal safety protocols.
However, for locations with strong tides or deeper-water reefs, a guide not only helps navigate safety but may also increase the chances of spotting elusive marine life like reef sharks, turtles, or mantas.
When to Choose a Guided Trip vs. When DIY Works
To give you a clearer idea of when a guided trip is the better option and when a DIY plan would do just fine, here’s a table that summarizes both approaches.

When Should You Do It?
Whether you prefer to snorkel or dive, choosing when to hit the water can either make or break your Bali marine adventure as timing affects visibility, marine activity, comfort, and safety.
The best time to go snorkeling or diving in Bali is during the dry season, which typically spans from April to October. This is when Bali enjoys calmer seas, minimal rainfall, and crystal-clear visibility—ideal conditions for exploring vibrant coral gardens and spotting marine life. Visibility is also excellent, often reaching up to 40 meters in locations such as Nusa Penida, Menjangan, and Tulamben, while the seas remain calm and light rains are rare.
Early mornings are especially rewarding. The water tends to be clearer, marine creatures are more active, and the crowds haven’t arrived yet, giving you a more peaceful underwater experience.
Here’s what else to keep in mind:
- Early mornings offer the best conditions. Waters are generally calmer and clearer, marine creatures tend to be more active, and the sites are far less crowded making for a more peaceful and rewarding experience.
- Peak visibility usually falls between May and September, with underwater clarity reaching up to 30 meters in some areas.
- Marine life sightings such as turtles, reef fish, and even larger species like manta rays or reef sharks are generally more frequent during sunlit hours, especially in the morning when feeding and movement patterns are in full swing.
- April to September combines the best of both worlds. April to June brings excellent water clarity and lighter tourist crowds, while July to September is prime time for spotting rare marine species. However, deeper waters during this peak period can drop to 23–25 °C, so a thicker wetsuit is often recommended for divers.
- Avoid diving or snorkeling after heavy rains or during Bali’s wet season (November to March), when water visibility drops, currents strengthen, and runoff can cloud coastal areas.
- Full moon and new moon periods can bring stronger currents due to tidal changes, so extra caution is needed during these lunar phases, especially if you’re exploring without a guide.
- Steer clear of sites known for strong currents and sudden temperature shifts like Nusa Penida especially outside the dry season, as these conditions can make diving risky for solo adventurers or those with limited experience.
Understanding these seasonal and daily patterns will help you plan your water activities for the safest and most rewarding marine encounters.
Top Snorkeling and Diving Spots in Bali
Now that you know the ins and outs of Bali’s underwater world and how to time your trip right, it’s time to explore where to actually go.
Below are the top snorkeling and diving spots in Bali, each offering its own underwater charm, from calm coastal bays to thrilling drift dives.
Best for Snorkeling: Clear and Calm Bali Beaches and Bays
Blue Lagoon (Padang Bai)
Blue Lagoon in Padang Bai lives up to its reputation as one of Bali’s most accessible and beginner‑friendly snorkeling destinations, especially for those seeking a laid-back experience without needing a boat ride. Tucked just north of Padang Bai, this small bay features a sandy-bottomed seabed and consistently calm waters, making it accessible even for first-timers. The reef here is just a few meters from the shoreline, teeming with highly diverse marine life. Visibility here is usually excellent (often between 15 and 25 meters), especially during the dry season when the sea is clearest.
What sets Blue Lagoon apart is its tranquil setting and convenience. It’s close to South Bali yet feels far removed from the busy tourist zones. The beach is quiet and backed by cliffs and a few warungs, giving it a semi-hidden charm. Plus, most snorkeling takes place on the right-hand side of the bay, where coral thrives and the seafloor gently slopes, naturally separating snorkelers from swimmers and creating a safer, more focused environment.
Beneath the surface, snorkelers are welcomed by schools of colorful reef species including angelfish, parrotfish, clownfish, and cowfish as well as curious cuttlefish and occasional moray eels. Macro photographers can also find nudibranchs and ghost pipefish lurking in reef rubble. While the site may not be densely packed with large pelagics, visitors frequently spot turtles and, during quieter tidal periods, even white‑tip reef sharks cruising the deeper edges of the reef. For this, many travelers praise its “finding Nemo” feel, only without the crowds and certainly without the effort.
- Location: Blue Lagoon Beach, Padang Bai, East Bali
- Access: Shore entry via sandy bay, often reached by a local boat ride of 5–10 minutes
- Entrance fee: Local parking fee (~IDR 5,000 for cars); snorkeling itself is free if renting on-site gear
- Snorkeling gear available for rent: Masks, fins, snorkels, life jackets (approx. IDR 50,000; negotiable)
- Tours available: Guided half‑day packages (~USD 50–90) include hotel pick‑up, gear, boat transfers, guide, and lunch at Tanjung Jepun
- Best time to snorkel: Early morning for calm water, clearer visibility, and more active marine life; avoid high tide or windy conditions for easier entry and exit points
Lipah Beach (Amed)
Lipah Beach in Amed is widely regarded as one of the most serene and accessible snorkeling spots on Bali’s northeast coast. Located just a short stroll from the shore, the vibrant coral garden is easily reached at high tide, making it ideal for both beginner snorkelers and families seeking a relaxed underwater experience. The water is typically calm and clear, with visibility often exceeding 15 meters. This tranquil setting allows you to glide over massive table corals, sea fans, and barrel sponges while watching colorful reef fish like butterflyfish, parrotfish, and angelfish.
Marine life here extends beyond fish. Sea turtles frequently glide past early in the morning, and experienced observers may spot juvenile reef sharks or goatsfish near the edges of the reef. Macro photographers often find nudibranchs, ghost pipefish, and juvenile harlequin sweetlips hiding amid the rubble. The snorkeling area is best accessed from the Vienna Beach Resort side, where a marked channel leads over a gentle slope to the reef wall. Most visitors praise Lipah Beach for its combination of easy access, rich biodiversity, and peaceful atmosphere—creating a memorable yet effortless snorkeling adventure.
Despite being quieter than neighboring Jemeluk Bay, Lipah still offers practical amenities. Beachside warungs provide simple meals, snorkel gear is available for hire, and the proximity to resorts like Vienna Beach makes equipment rentals and parking convenient. Many travelers choose Lipah for morning sessions when the sea is calmest and wildlife is at its most active.
- Location: Lipah Beach, Amed, on the northeastern coast of Bali (near Vienna Beach Resort)
- Access: Free shore entry; easiest at high tide via marked channel to reef
- Snorkeling conditions: Calm waters, visibility usually 15–25 meters, ideal for beginners
- Marine highlights: Table corals, red sea fans, butterflyfish, turtles, nudibranchs, occasional juvenile reef sharks and cuttlefish
- Equipment: Masks, fins, snorkels, life jackets available to rent from beach stalls or nearby resorts
- Best time to visit: Early morning (around 8–9 AM) during the dry season (April to October) for optimal visibility and active marine life
- Nearby facilities: Beachside warungs, sunbeds, resorts for storage and relaxation
Jemeluk Bay (Amed)
Another spot in Amed worth visiting is Jemeluk Bay, a scenic and sheltered curve of coastline that delivers a relaxed yet rewarding snorkeling experience. Nestled along the volcanic coastline of eastern Bali, it boasts calm, clear waters and gentle sloping depths that mean you can step straight off the beach and find yourself surrounded by coral gardens within a few meters. Visitors commonly glide above thriving table corals and sea fans, while schools of diverse fish—such as angelfish, surgeonfish, and damselfish—dance among the reef. For many snorkelers, the highlight is the underwater temple, also known as the “Underwater Post Office,” located a short swim from shore. These statues sit between 5 to 6 meters deep and support coral growth while creating a visually striking artificial reef that is visible even from the surface on clear days.
Beneath the surface, the marine life at Jemeluk Bay spans from macro favorites to mid-size reef dwellers. In shallower zones you may spot nudibranchs, ghost pipefish, and reef octopus tucked into crevices. Deeper along the reef wall there are occasional sightings of blue-spotted rays, scorpionfish, and even pygmy seahorses. The underwater topography is enriched by natural coral formations and artistic structures that attract cleaner shrimp and a wide variety of tropical fish. Snorkeling here is peaceful yet brimming with surprises—even reef sharks and turtles make occasional appearances along the deeper edge of the bay.
- Location: Jemeluk Bay, Amed (east coast of Bali, within the North Seraya region)
- Access: Free shoreline entry; reef drop-off begins approx. 20–70 meters from the beach
- Visibility: Generally 15–25 meters during dry months (April–October)

Mangrove Point (Nusa Lembongan)
Lastly, a great snorkeling spot outside of mainland Bali is Mangrove Point on Nusa Lembongan. Tucked along the island’s tranquil northeastern coast, this site offers one of the most effortless and awe-inspiring snorkeling experiences in the region. The spot is named after the lush mangrove forest that lines the shore, which plays a crucial role in keeping the waters crystal clear and the marine ecosystem thriving. Here, snorkelers can drift along the reef with the current, floating effortlessly over expansive coral gardens, making it ideal for beginners and non-swimmers who still want to enjoy vibrant underwater life without strenuous swimming.
What makes Mangrove Point truly special is the diversity and density of its marine life. Expect to see carpets of healthy hard and soft corals in vivid hues (e.g., table corals, staghorn, and brain corals dominate the seafloor), creating a perfect habitat for schools of reef fish. Snorkelers often spot anemonefish (clownfish), butterflyfish, parrotfish, angelfish, and trumpetfish weaving through the coral branches. The occasional green sea turtle or moray eel might even glide by. Visibility is outstanding, often reaching up to 25 meters on clear days, revealing the full spectacle of the reef in all its color and movement.
Compared to other snorkeling spots around Bali and the Nusa islands, Mangrove Point stands out for its calm conditions and well-preserved reef system, thanks in part to the natural protection from the mangroves and low-impact tourism practices. It’s less crowded than popular sites like Crystal Bay or Manta Point, giving visitors a more serene and immersive snorkeling experience. The gentle currents allow you to drift for hundreds of meters while observing uninterrupted coral formations, making it feel like a slow underwater tour through a living reef museum.
- Location: Northeast coast of Nusa Lembongan, near the mangrove forest
- Entry Access: Boat drop-off required; short boat ride from Jungut Batu or Mushroom Bay
- Water Conditions: Generally calm drift snorkeling; mild currents depending on tide and lunar phase
- Visibility: Excellent, often between 20 and 25 meters
- Best Time to Visit: High tide and early morning offer the most comfortable conditions and greatest marine activity
- Tour Options: Often combined with mangrove forest tours; available via local operators from Nusa Lembongan
Best for Diving
Manta Point (Nusa Penida)
Perhaps the best location to spot manta rays is Manta Point in Nusa Penida. Named one of the top diving sites in Bali and globally acclaimed for manta encounters, this offshore gem offers an unforgettable underwater experience. The site’s main highlight is a shallow cleaning station, around 10 meters deep, where majestic reef manta rays glide in gracefully to be cleaned by small fish. It’s not unusual to witness ten or more of these gentle giants swimming in slow circles, often passing directly overhead—a rare and thrilling spectacle for divers and snorkelers alike.
What makes Manta Point truly unique is not just the mantas, but the vibrant marine biodiversity and topography surrounding the site. A gently sloping reef descends into deeper waters (up to 40 meters), home to blue-spotted stingrays, bamboo sharks, moray eels, octopuses, turtles, and during colder months, the elusive mola mola (sunfish). The combination of pelagic sightings and rich reef life makes this a dream site for underwater photographers and marine life enthusiasts.
However, beauty comes with challenges. Manta Point lies in a convergence of strong ocean currents and plankton-rich waters, which draw in the mantas but also bring colder temperatures (as low as 20°C) and occasional surge. Visibility typically ranges from 10 to 20 meters, though this seldom affects manta sightings due to their large size. These dynamic conditions make it best suited for experienced divers or snorkelers with guides.
While the site can get crowded with boats, especially mid-morning, visiting early in the day usually offers calmer seas and a more serene encounter with these magnificent creatures. Manta Point remains a bucket-list location for anyone seeking one of Bali’s most magical and humbling marine experiences.
- Location: South of Nusa Penida Island, reachable via boat from Bali (Sanur, Padang Bai, or Amed)
- Snorkeling/Diving Type: Boat-access drift dive or guided snorkel
- Marine Highlights: Reef manta rays, blue-spotted stingrays, bamboo sharks, turtles, octopus, moray eels, occasional mola mola
- Visibility: 10–20 meters depending on current and season
- Water Temperature: 20–27°C; colder during July–September
- Skill Level: Intermediate to advanced (due to surge, currents, and open water conditions)
- Best Time to Visit: April to November for better conditions and fewer waves
- Special Tip: Early morning trips offer calmer water and fewer crowds
Crystal Bay (Nusa Penida)
If you’re fond of ocean sunfishes like the mola mola, then Crystal Bay in Nusa Penida deserves a spot on your dive list, especially during the cooler months. Here, divers can descend through a steep reef ridge toward depths of 25 to 30 meters, where the deep channel between Nusa Penida and Nusa Ceningan upwells cold, plankton-rich water. The result is spectacular manta-sized sunfish sightings and a reef teeming with marine life such as frogfish, moray eels, napoleon wrasse, eagle rays, reef sharks, and schooling trevally. Visibility is often excellent, typically ranging between 20 and 30 meters, revealing vibrant coral gardens and macro subjects like nudibranchs and ghost pipefish.
That said, diving Crystal Bay is not for the faint-hearted. Currents can be unpredictable with sudden downflows and wave action increasing the risk of being swept off the reef so this site is best suited for intermediate to advanced divers. Water temperatures during mola season (July to October) can drop to as low as 16 °C near deeper depths, requiring appropriate thermal protection and cautious planning. Divers frequently recommend early morning dives to avoid crowds and benefit from calmer sea conditions. Despite the challenges, Crystal Bay remains a bucket-list destination for those seeking rare encounters in crystal-clear waters and dramatically rich biodiversity.
- Location: West coast of Nusa Penida, accessed by boat from Sanur, Padang Bai, or Nusa Lembongan
- Type: Advanced dive site (drift dive, deep channel)
- Marine Highlights: Mola mola (seasonal), manta rays, reef sharks, eagle rays, napoleon wrasse, frogfish, nudibranchs, trevallies

USAT Liberty Shipwreck (Tulamben)
One of Bali’s most iconic dive sites: the USAT Liberty Shipwreck in Tulamben. Resting just offshore from a black-sand beach, this World War II vessel has transformed into a vibrant artificial reef stretching from shallow water at around five meters to deeper sections at thirty meters. The wreck is home to an incredible array of marine life—schools of jacks swirl overhead, anthias dart among coral fragments attached to the hull, and larger creatures like barracuda, wrasse, and occasional reef sharks patrol nearby.
Beneath the surface, divers of all levels can explore this submerged treasure. At shallow depths, snorkelers can still spot colorful reef fish, while deeper sections are popular with certified divers examining the ship’s upper decks, engines, and portholes now encrusted by corals. Macro enthusiasts will enjoy spotting nudibranchs, frogfish, pipefish, and cleaner shrimp clinging to both wreck and reef. The wreck’s vertical profile and the gentle sandy slope beyond it make for a site that combines history, accessibility, and biodiversity into one memorable dive.
Visibility at Tulamben varies from 15 to 30 meters depending on conditions, and currents are typically mild—ideal for a relaxed exploration. Although suitable for beginners with proper guidance, the site offers enough intrigue to satisfy advanced divers too.

Japanese Shipwreck (Amed)
For those who are not yet convinced to either snorkel or dive, or those who’d like to try both, the Japanese Shipwreck in Amed offers the perfect opportunity to ease into Bali’s underwater wonders. Located just offshore in Banyuning Bay, this small but historically intriguing World War II-era wreck rests in shallow water, starting at around 2 meters deep, making it accessible even for beginner snorkelers. Yet just beside it lies a dramatic reef slope that descends to 30 meters, attracting divers with its flourishing marine biodiversity.
What makes this site truly special is its seamless blend of shallow snorkeling fun and deeper reef exploration. The wreck itself is encrusted with vibrant soft corals, sea fans, and sponges, sheltering glassfish, damselfish, clownfish, and occasional lionfish within its broken frame. Along the deeper sections, divers can encounter unique macro species like leaf scorpionfish, ghost pipefish, nudibranchs, and even pygmy seahorses, while eagle-eyed visitors might also spot stonefish and crocodile flatheads camouflaged in the sand.

Menjangan Island (Northwest Bali)
Although categorized as a protected marine area, Menjangan Island combines pristine conservation with some of Bali’s most rewarding snorkeling and diving experiences. Located within Bali Barat National Park, the site features dramatic wall dives and coral gardens known for excellent visibility and calm conditions. Popular entry points drop you into shallow reefs starting at about 5 meters, descending gently along walls that reach 40 to 60 meters. These reefs are dotted with giant gorgonian sea fans, barrel sponges, and rich soft-coral growth, creating a biodiverse underwater world that is both accessible and awe-inspiring for explorers of all skill levels.
For snorkelers, the nearby coral flats and reef-top zones offer calm, clear water where colorful reef fish such as angelfish, batfish, clownfish, and big-eye trevally thrive. Divers venturing deeper along the wall dive zones—sites like Garden Eel Point, Pos II, and Bat Cave—are rewarded with sightings of pygmy seahorses, moray eels, sharks, turtles, and even garden eel colonies swaying above the sandy slopes. The site named Anchor Wreck adds historical intrigue to the experience—this old wooden boat lies partially submerged and encrusted with living coral at depths around 35 to 50 meters, attracting schooling fish and occasional reef sharks.
Despite not being a hotspot for large pelagic species, Menjangan impresses with superb water clarity—often reaching 30 to 50 meters during the dry season—and gentle conditions that make it a top recommendation for families and novice divers. Dive operators and travelers frequently praise the island for its quiet atmosphere and easy logistics: shore entry and boat drops over protected zones, low currents, and consistent visibility year-round. Just expect tight marine protocol here as compared to any spot on this list—this is a conservation zone, and all activities are closely monitored to protect the fragile ecosystem.

Biorock Reef (Pemuteran)
Lastly, if you want to try both diving and snorkeling in a meaningful and beginner-friendly environment, the Biorock Reef in Pemuteran is the perfect place to start. As the name suggests, this site showcases a network of artificial reef structures designed to regenerate coral growth using an innovative technology called Biorock. These sunken metal domes, shaped into everything from basic grids to creative sculptures, are connected to low-voltage electric currents that stimulate faster coral growth—up to five times faster than natural rates. What’s more, the calm, clear waters of Pemuteran Bay make it accessible to both snorkelers and divers, offering a unique blend of science, conservation, and underwater beauty.
The project began in the early 2000s, when Pemuteran—a quiet fishing village in North Bali—was grappling with reef damage caused by coral bleaching and destructive fishing practices. In collaboration with local communities, the Karang Lestari Foundation and international scientists launched the Biorock initiative to restore the reefs and support sustainable ecotourism. Today, over 115 structures span the bay, making it the world’s largest Biorock reef site. Visitors can even find plaques commemorating donors and milestones, turning the area into a living reef gallery that grows and evolves each year.
Aside from its ecological impact, the Biorock Reef offers an inspiring and peaceful marine experience. Expect tight marine protocol here compared to other spots on this list—touching corals or standing on reef areas is strictly prohibited. Visibility is typically high, currents are gentle, and the reef begins just a few meters from shore. Whether you’re floating above it with a snorkel or gliding through the structures on a dive, you’re not just enjoying marine life—you’re witnessing and supporting a global conservation movement in action.

- Dive Type: Shore dive; no boat needed
Know These Before You Go Experience Bali’s Underwater Tourism Firsthand
Lastly, before you’ll be all set to meet the teeming marine life and vibrant coral ecosystem of Bali, you must first know these know-hows. Not only does it ensure your safety, but it also helps preserve Bali’s fragile marine environments for future generations.
Gear Recommendations
- Mask & Snorkel: Invest in a high-quality, well-fitting mask and snorkel. A good seal keeps water out and enhances your visibility, while a dry-top snorkel can prevent water from entering if waves splash over you.
- Fins: Choose lightweight, open-heel or full-foot fins that are easy to control. They allow you to glide efficiently without touching the seabed or disturbing marine life.
- Rash Guard or Wetsuit: These offer protection from the tropical sun, jellyfish stings, and minor scrapes from coral or rocks. A long-sleeved rash guard is often enough in Bali’s warm waters.
- Reef-Safe Sunscreen: Avoid sunscreens with oxybenzone or octinoxate, which are toxic to corals. Look for mineral-based sunscreens containing zinc oxide or titanium dioxide and apply them at least 15 minutes before entering the water.
Safety Tips
- Snorkel with a Buddy: Never snorkel alone, even in calm waters. A partner can assist in emergencies and help keep an eye out for strong currents or sudden changes in conditions.
- Check Weather, Tides, and Currents: Always consult local tide charts and weather forecasts before heading out. Strong currents can quickly carry snorkelers away from shore.
- Respect Coral: Never stand, step on, or touch coral. Corals are delicate living organisms, and even the lightest contact can cause irreversible damage.
- Watch for Hazards: Be mindful of sea urchins, fire coral, and jellyfish. Keeping a safe distance helps you avoid stings and injuries.
- Stay Calm and Aware: Avoid panicking if water gets into your mask or snorkel. Practice clearing your gear before your trip and always stay within a depth where you can comfortably swim.
Conservation & Reef Etiquette
- Avoid Kicking Up Sand or Sediment: Disturbed sand can cloud the water and suffocate corals. Swim horizontally with your fins up to minimize impact.
- Keep Your Distance from Marine Life: Don’t chase, touch, or corner fish, turtles, or rays. Let them move freely and observe them without interference.
- Support Local Conservation Efforts: Book with eco-certified tour operators and guides who follow marine protection protocols. Programs like the Biorock Project and local marine sanctuaries benefit directly from responsible tourism.
- Bring Back Only Memories: Do not take shells, coral fragments, or marine life as souvenirs. These are essential parts of the ecosystem and often protected by law.
- Reduce Plastic Waste: Avoid bringing single-use plastics on boat trips. Bring a reusable water bottle, dry bag, and reef-safe products to minimize your environmental footprint.

Your Saltwater Stories Told in Fins
Some of Bali’s best stories aren’t found in temples or rice fields. They’re told in bubbles, drift currents, and sudden flashes of reef color just below the surface. In those quiet, weightless moments underwater, you discover a version of Bali that few truly get to know.
Gear up, dive in, and let Bali’s rich marine life transform your vacation into a journey of wonder and connection. Just remember: respect the ocean, protect what you love, and take only memories (and photos) with you as you surface.
So don’t just skim Bali. Dive deep! The ocean here isn’t just beautiful. It’s unforgettable.
