Raja Ampat is widely considered one of the best places for scuba diving in Indonesia. Located in the heart of the Coral Triangle off the coast of West Papua, this remote archipelago is home to some of the highest levels of marine biodiversity on Earth. Descend beneath the surface and you'll find spectacular coral gardens alive with colour, swirling schools of fusiliers and barracuda, reef sharks cruising along dramatic drop-offs, and manta rays gliding through cleaning stations. It's the remarkable abundance of life, rather than just a handful of flagship species, that makes every dive here feel extraordinary.

Raja Ampat is equally revered by underwater photographers and experienced divers for its diversity. In a single dive you can encounter wobbegong sharks resting on the reef, turtles drifting through crystal-clear water, or tiny pygmy seahorses hidden among sea fans. Combined with untouched island scenery, limestone karsts, and hundreds of dive sites ranging from exhilarating drift dives to intricate macro photography hotspots, Raja Ampat has earned its reputation as one of the world's top diving destinations.

Small in size but famous among the scuba diving community, Koh Tao has introduced thousands of divers to the underwater world. Calm conditions, warm water, and plenty of dive centres make it one of Asia's most popular places to earn an Open Water certification.

For many divers, scuba diving in Thailand's Koh Tao is where a lifelong passion for the sport begins. The island has built its reputation on making the underwater world accessible, whether you're taking your first breaths beneath the surface or developing your skills on more challenging sites. Beneath the water, you'll find colourful coral gardens, submerged pinnacles, and artificial reefs that attract turtles, barracuda, trevally, and, on occasion, whale sharks. While some of Asia's top dive destinations are known for remote locations and demanding conditions, Koh Tao's appeal lies in its ability to deliver memorable marine encounters in a welcoming environment that keeps divers returning long after they've earned their first certification.

The reefs themselves are vibrant and well-preserved, with colourful coral formations and excellent year-round diving conditions.

With fewer boats and divers than some of the Maldives' more famous regions, Gaafu Alifu’s underwater encounters often feel more intimate. Whether you're drifting through channels alive with pelagic species or exploring coral gardens teeming with life, it's easy to see why experienced divers consider the southern atolls among the Maldives' hidden gems.

Komodo National Park is renowned for thrilling drift dives, dramatic underwater topography, and some of Indonesia's best manta ray encounters. Strong currents flowing between the islands create nutrient-rich waters that attract everything from reef sharks and giant trevallies to large schools of barracuda and snapper. Iconic dive sites such as Batu Bolong, Crystal Rock, and Manta Point are considered among the best in Southeast Asia.

What sets Komodo apart from other dive sites in Asia is the variety. One dive can take you across colourful coral-covered pinnacles teeming with reef fish, while the next could bring close encounters with manta rays soaring through cleaning stations. Combined with the park's rugged volcanic landscapes and uninhabited islands, diving in Komodo feels like exploring one of the last truly wild corners of Indonesia.

Goa may be best known for its beaches and laidback coastal lifestyle, but it also offers some of India's best diving. Most dive trips head offshore to sites around Grande Island, where you'll find reefs, rocky outcrops, and wrecks that support a variety of marine life. Calm conditions and relatively shallow dive sites make the region particularly appealing to first-time divers and those completing certification courses.

Scuba diving sites such as Suzy's Wreck, Sail Rock, Uma Guma Reef, and Turbo Tunnel offer a mix of wreck exploration, swim-throughs, and coral-covered formations inhabited by angelfish, triggerfish, rays, moray eels, and other tropical marine species.

Type of diving: Drift, reef, pelagic encounters

Just off Bali's south-east coast, Nusa Penida has become one of Asia's most sought-after dive destinations thanks to its frequent manta ray encounters and seasonal sightings of the elusive mola mola, or ocean sunfish. The island's dramatic underwater landscape includes steep walls, healthy reefs, and nutrient-rich currents that attract a range of marine life.

Exploring Nusa Penida is rarely about a single dive site. Most day trips combine several locations, each offering a different experience. You might begin at Manta Point, where manta rays glide through cleaning stations, before heading to sites such as Toyapakeh or SD Point, known for their exhilarating drift dives, healthy coral reefs, and exceptional visibility. At Crystal Bay, divers visit in the hope of encountering mola mola during the cooler months. This variety, combined with Bali's accessibility and the island's spectacular coastal scenery, makes Nusa Penida one of Southeast Asia's most exciting places to go scuba diving.

Many dive operators in Asia offer introductory or discovery dives that allow beginners to experience scuba diving under the supervision of a qualified instructor, and you don’t need to hold a diving certification to undertake these. However, a diving certification from a reputable training organisation, such as PADI or SSI, is required for most multi-day diving trips and advanced dive sites in Asia.

Koh Tao, Nha Trang, Goa, and selected sheltered sites in Gaafu Alifu Atoll are some of the best scuba diving sites in Asia for beginner divers. Conditions vary by dive site and season, so confirm current requirements with a qualified local operator before booking.

An Open Water certification is sufficient for many dive sites across Asia. If you're planning to explore deeper reefs, wrecks, or drift dives, an Advanced Open Water certification may provide access to a wider range of sites.

Non-divers can enjoy most of Asia’s top diving sites. Many of these destinations also offer snorkelling, beaches, island tours, wildlife experiences, cultural attractions, and resort facilities. Places such as Bali, Okinawa, Phuket, Cebu, and Goa are popular with both divers and non-divers.

If you’re heading to Asia for a dive trip, most dive operators provide rental equipment, including masks, fins, wetsuits, regulators, and buoyancy control devices (BCD). Some experienced divers choose to bring their own dive computer, mask, and other personal gear for comfort and familiarity.

Liveaboard diving trips in Asia can provide access to remote dive sites that are difficult to reach on day trips. They are particularly popular in destinations across Asia such as Raja Ampat and Komodo National Park, where travelling between dive sites can take considerable time.

Popular diving destinations and resorts in Asia can book out well in advance during peak seasons. Booking early can provide greater choice of accommodation, flights, dive operators, and liveaboard itineraries, particularly in sought-after destinations such as Raja Ampat, Komodo, and the Maldives.
