Best Scuba Diving in the World: 11 Bucket-List Spots

For anyone who loves the underwater world, scuba diving is the ultimate adventure, and chasing the best scuba diving in the world has shaped a lot of our travels. From colourful coral gardens and shark-filled drop-offs to atmospheric wartime wrecks, the planet’s oceans hold some genuinely world-class dives, each with its own character. As full-time travellers and keen divers, we’ve personally dived eight of the eleven destinations below, so this is a mix of our own first-hand favourites and a few legendary spots that belong on any serious diver’s list. We’ve noted honestly which is which.

Scuba Diving Around the World at a Glance

The full eleven are covered in detail below, but if you’re short on time, the comparison table that follows is the quickest way to match a destination to the kind of diving you’re after.

The Best Scuba Diving Destinations Compared

Every destination on this list is world-class, but each is best for something different, whether that’s big animals, sheer biodiversity, wrecks, or simply learning to dive in warm, forgiving water. Here’s how the eleven compare at a glance, so you can match a destination to the kind of diving you’re after before reading on.

A few of these destinations are gentle enough for a very first dive, while others demand a logbook full of experience and a tolerance for strong current. If you’re not sure where you fit, here’s where to start.

Cozumel, Mexico

Cozumel’s warm, clear blue water, easy drift dives and diverse marine life make it one of the best places to dive in Mexico, and a brilliant place to learn. We loved the relaxed pace here. The island sits on the Mesoamerican Barrier Reef, the second-largest reef system in the world, and is home to over 250 species of fish along with turtles, moray eels, and nurse and bull sharks. The dry season (December to April) brings the calmest, clearest water and the biggest crowds, while March to June is the sweet spot to dive before the rains while the tourist numbers thin out.

Best dive sites in Cozumel

Palancar Reef is the headline act, a sprawling complex of five dive sites at 15–35 m suitable for all levels, with eagle rays, nurse sharks and turtles drifting past beautiful coral formations. Columbia Deep is a dramatic wall dive for intermediate and advanced divers, dropping off abruptly just past Devil’s Throat. For beginners, Chankanaab Reef in the National Reef Marine Park tops out at 40 ft with a mild current and easy shore access, where rays, amberjacks and turtles are common.

Where to stay: Cozumel’s dive hotels cluster near the marine park and the ferry terminal, with plenty of mid-range options offering dive packages and easy boat access to the reef.

Sipadan, Malaysia

Sipadan, a tiny island off the east coast of Malaysian Borneo, is regularly ranked among the best dives on earth, and it lived up to every bit of the hype for us. It’s home to over 3,000 species of fish, hundreds of types of coral, and huge schools of barracuda and jackfish that swirl into mesmerising tornado-like formations. Because it’s a protected marine park, only a limited number of permits are issued each day, which keeps it from ever feeling crowded; we were struck by how few other divers we saw. You’ll need to book a dive package with a certified operator to secure a permit, but the surrounding sites are superb too. For the full rundown, see our guide to diving in Sipadan.

Best dive sites in Sipadan

Barracuda Point is ranked among the world’s top five dive sites, named for the tornado of barracuda that often circles overhead; it’s a 40 m drift dive and an absolute highlight. The Drop-Off is a 600 m wall just 10 m from the beach, thick with turtles, sharks, cuttlefish, octopus and ribbon eels. South Point is great for sharks and bright coral gardens, but the strong currents make it one for confident divers only.

Where to stay: Most divers base themselves in Semporna the mainland gateway town, where guesthouses and dive lodges sit close to the markets and the boats out to the dive sites.

Galapagos Islands, Ecuador

The Galapagos is big-animal diving at its absolute best, and one of the most thrilling places we’ve ever got in the water. With more than 28 species of shark (schooling hammerheads among them), plus whale sharks, sea lions, marine iguanas, penguins and the red-lipped batfish you can see nowhere else on earth, it’s a genuinely unique experience. The strong currents and challenging conditions mean it’s best suited to advanced divers, and while you can day-trip to some sites from the inhabited islands, the very best diving at Wolf and Darwin Islands is reachable only by liveaboard. Timing is everything here. Our guide to the best time to visit the Galapagos breaks the seasons down month by month.

Best dive sites in the Galapagos

Darwin Island (the sites of El Arco and El Arenal) delivers schooling hammerheads, whale sharks, dolphins and eagle rays in strong current, liveaboard-only and genuinely world-class. Roca Redonda off Isabela Island is a volcanic site where fumaroles bubble up through the water and sea lions, Galapagos sharks, manta rays and scalloped hammerheads cruise past. These are bucket-list dives that reward the effort it takes to reach them.

Where to stay: Liveaboards are the way to dive the Galapagos but if you’re basing on land, the town of Puerto Ayora on Santa Cruz has the widest choice of hotels and day-dive operators.

Raja Ampat, Indonesia

If we had to pick a single number-one, it would be Raja Ampat. This remote archipelago of over 1,500 islands in West Papua has the richest marine biodiversity on the planet, and diving its coral gardens, swim-throughs, underwater caves and steep drop-offs is simply staggering. It works for all levels, though some sites have serious current, and operators run everything from day trips to multi-day liveaboards. The sheer density of life here is unlike anywhere else we’ve dived, and it’s the one destination on this list we’d cross the planet to dive again.

Best dive sites in Raja Ampat

Cape Kri holds the world record for the most fish species seen on a single dive, a genuinely jaw-dropping wall of life. Misool Island is a soft-coral paradise and a dream for underwater photographers, home to mandarin fish, crinoid shrimp and arrowhead crabs. Melissa’s Garden is a vibrant reef of hard and soft corals teeming with smaller marine life, and a favourite for both beginners and experienced divers.

Where to stay: Raja Ampat’s eco-resorts range from simple homestays on Kri and Gam islands to upmarket dive lodges, all with house reefs and boats out to the sites; book well ahead, as space is limited.

Komodo, Indonesia

Komodo National Park is manta country, and diving here is some of the most exciting in Indonesia. Cooler, plankton-rich water draws in mantas, reef sharks, turtles and huge schools of fish, often in strong current that makes for thrilling drift dives. The best way to experience it is on a liveaboard, though you can also base yourself in the gateway town of Labuan Bajo and day-trip out. Our Komodo liveaboard experience covers exactly what it’s like aboard, from the diving to the Komodo dragons on land.

Best dive sites in Komodo

Manta Point is exactly what it sounds like, a cleaning station where mantas glide in year-round, with December to February the peak as cooler, plankton-rich water arrives. Batu Bolong is a towering pinnacle dropping past 70 m, swarming with fish, reef sharks and the occasional manta in fierce current, for experienced divers only. Tatawa Besar is a gentler, colourful sloping reef of soft and hard corals that suits all levels, with nudibranchs, turtles and reef sharks.

Where to stay: Labuan Bajo is the launch point for Komodo, with everything from backpacker rooms to luxury resorts with their own dive centres and easy access to the park’s boats.

Bali, Indonesia

Bali punches well above its weight underwater, and it’s one of the most accessible world-class dive destinations anywhere. Off Nusa Penida we dived with enormous oceanic manta rays at Manta Point, gliding in one after another at the cleaning station. In the colder months, the island is also one of the few places on earth to see the bizarre, prehistoric-looking mola mola (oceanic sunfish). Over on the east coast at Tulamben, the USAT Liberty shipwreck is one of the most popular wreck dives in the world, draped in coral and accessible straight from the beach. It suits everyone from first-timers to seasoned divers. See our guide to the best dive sites in Bali for the full list.

Best dive sites in Bali

Manta Point off Nusa Penida is a reliable year-round cleaning station for oceanic mantas, and one of the most dependable manta dives anywhere. Crystal Bay is the spot for those rare mola mola sightings between July and October, though the cold thermoclines and current make it an advanced dive. The USAT Liberty wreck at Tulamben is a beginner-friendly shore dive, a coral-encrusted hull patrolled by bumphead parrotfish and schools of jack.

Where to stay: Base near the diving on Nusa Penida or Nusa Lembongan for the mantas, or in the dive village of Amed or Tulamben on Bali’s east coast for the Liberty wreck and easy shore diving.

Ningaloo Reef, Australia

On the remote northwest coast of Western Australia, Ningaloo Reef is one of the world’s largest fringing reefs, and in our opinion every bit as impressive as the more famous Great Barrier Reef. It’s home to over 500 species of fish, turtles, manta rays, tiger sharks and, between March and July, the world’s biggest fish: the whale shark. With a maximum depth of around 15 m, excellent conditions year-round and plentiful shore dives, it’s wonderfully beginner-friendly and a dream if you like diving with your own gear. Our guide to visiting Ningaloo Reef has the full picture, including swimming with the whale sharks.

Best dive sites in Ningaloo

Navy Pier, a former naval dock turned marine sanctuary near Exmouth, is rated one of the best shore dives in the world, packed with fish, octopuses, turtles, wobbegongs and grey nurse sharks. Lighthouse Bay is a shallow, beginner-friendly site full of anemonefish, and a great place to find your fins. The Muiron Islands offer pristine coral gardens, walls and swim-throughs with reef sharks, mantas and turtles, suiting all levels.

Where to stay: The town of Exmouth is the main base for Ningaloo, with hotels, dive operators and the boats out to the reef, while eco-camps sit right on the beach inside the national park.

Lighthouse Reef Atoll, Belize

A UNESCO World Heritage Site and part of the Belize Barrier Reef Reserve, Lighthouse Reef Atoll in the Caribbean is world-famous for one thing above all: the Great Blue Hole. This vast underwater sinkhole, roughly 300 m across and over 120 m deep, is one of the most iconic dives on the planet, with crystal-clear water and walls draped in coral and ancient stalactites. It’s an advanced dive, and a true bucket-list site, though we’ll be honest: it’s one we haven’t made it to ourselves yet.

Best dive sites in Belize

The Great Blue Hole is the headliner, famous for its dramatic vertical formations and stalactites at depth, with Caribbean reef sharks and giant groupers patrolling the walls. Many divers find the surrounding reef walls even more rewarding for marine life: Half Moon Caye Wall and Long Caye Wall nearby are teeming with reef sharks, turtles, eagle rays and a riot of colourful sponges and corals.

Where to stay: Dive the atoll from a liveaboard or an island lodge eco-resorts near the Great Blue Hole and on the outer cayes run trips to the atoll, or you can reach it on a long day trip from the mainland.

Red Sea, Egypt

Egypt’s Red Sea is one of the world’s great diving regions, and a famously good-value one. Sitting between Africa and Asia, it holds over 1,200 species of fish and around 10% of the world’s coral reefs, with visibility that can reach 60 m. It ranges from shallow coral gardens perfect for beginners to world-class wreck and drift dives, and you can expect hammerheads, giant turtles and dolphins. It’s high on our own list of regions still to dive, and an easy one to recommend for the sheer variety on offer.

Best dive sites in the Red Sea

The SS Thistlegorm is one of the best wreck dives in the world, a British WWII cargo ship sunk in 1941 with trucks, motorbikes and rifles still in its holds. The Abu Nuhas reef hides five shipwrecks on the seabed, home to octopus and giant moray eels, while Ras Mohammed National Park, Egypt’s first national park, protects towering walls with 220 species of coral and over 1,000 species of fish.

Where to stay: Dahab and Sharm el-Sheikh are the main dive bases on the Sinai coast, both with quick access to the famous reefs and wrecks and a wide range of dive hotels.

Palau

Palau, a small island nation in the western Pacific, is a legend among divers for its sharks, drift dives and dramatic underwater landscapes. Its waters teem with hundreds of species of fish, sharks, dolphins and turtles, alongside vibrant coral gardens and famous sites like Jellyfish Lake. The moderate-to-strong currents and the depth of many sites make it best suited to intermediate and advanced divers. It’s another iconic destination that’s firmly on our wish list rather than in our logbook, but no list of the world’s best diving would be complete without it.

Best dive sites in Palau

Blue Corner is one of the most famous dives on earth, where divers hook onto the reef edge to hang in the current and watch grey reef sharks, jacks and barracuda stream past. German Channel is a manta cleaning station with giant rays and grey reef sharks, and Ulong Channel is a thrilling drift past schools of snapper and batfish, well known as a shark-feeding spot.

Where to stay: The town of Koror is the diving hub, with resorts and dive operators that run daily boats out to Blue Corner, the German Channel and the Rock Islands.

Thailand

Warm water, beautiful reefs and famously affordable courses make Thailand one of the best places in the world to learn to dive, and a fun one to keep diving once you’re certified. There are over 340 named dive sites across the Andaman Sea and the Gulf of Thailand, suiting everyone from nervous first-timers to seasoned divers chasing whale sharks. We have great memories of diving here, especially the easy, social vibe of Koh Tao, where half the travellers seem to be mid-course.

Best dive sites in Thailand

The Similan Islands in the Andaman Sea are the showpiece, with coral gardens, granite gorges and seasonal whale sharks and mantas, usually visited by liveaboard. Koh Tao in the Gulf is the world’s certification capital, cheap and beginner-friendly, with reef sharks, barracuda and turtles on its house reefs. Chumphon Pinnacle is a granite seamount known for whale-shark and manta sightings, and one of the Gulf’s best dives.

Where to stay: Koh Tao for learning, Khao Lak for the Similans Koh Tao is wall-to-wall dive schools and cheap bungalows, while Khao Lak on the mainland is the jumping-off point for Similan Islands liveaboards.

Frequently Asked Questions

Where is the best scuba diving in the world?

There’s no single answer, but the destinations that top almost every list, including ours, are Raja Ampat and Komodo in Indonesia, the Galapagos, Sipadan in Malaysia, and the Red Sea. Each is world-class for different reasons, from sheer biodiversity to big-animal encounters.

What is the best scuba diving destination for beginners?

Warm, calm, clear-water spots are best to learn in. Cozumel in Mexico, Koh Tao in Thailand and the sheltered reefs of the Red Sea are popular, affordable places to get certified and build confidence, and Bali and Ningaloo are gentle too.

What is the number one dive site in the world?

Raja Ampat in Indonesia is the most common pick for sheer biodiversity, with the richest marine life on earth, while the Galapagos wins for big animals like schooling hammerheads and whale sharks. Cape Kri in Raja Ampat holds the record for the most fish species seen on a single dive.

Where can you dive with big animals like sharks and manta rays?

The Galapagos (hammerheads and whale sharks), Komodo and Bali (oceanic mantas), Ningaloo Reef in Australia (whale sharks, March to August) and Palau (reef sharks) are among the best places in the world for large pelagic encounters.

What is the best month for a scuba diving trip?

It depends on the destination. The Indo-Pacific (Raja Ampat, Komodo, Sipadan, Bali) is best in the dry season, roughly October to May; Ningaloo’s whale sharks run March to August; and the Galapagos is good year-round, with cooler, animal-rich water from June to November.

Is the Great Barrier Reef or Raja Ampat better for diving?

Raja Ampat has noticeably richer marine life and healthier reefs, while the Great Barrier Reef is more accessible and better set up for first-timers. For experienced divers chasing biodiversity, Raja Ampat usually wins; we’d also put Ningaloo Reef right up there among Australia’s dives.

Do you need to be certified to scuba dive at these destinations?

Yes, for real scuba diving you need at least an Open Water certification, but most of these destinations also offer Discover Scuba intro dives and excellent snorkelling, so beginners and non-divers aren’t left out.

Final Thoughts

This list could go on forever, but these eleven destinations are the ones we’d point any diver toward first. If we had to choose, Raja Ampat and the Galapagos top our own logbook for sheer wonder, Sipadan and Bali for the marine life, and Cozumel and Koh Tao are where we’d send anyone just starting out.
