Mind-blowing biodiversity

Made up of more than 17,000 islands spread across 735,000 square miles, Indonesia is the world’s largest island nation. Located on either side of the equator and bordered by both the Indian and Pacific Oceans, Indonesia boasts world-renowned dive destinations such as Raja Ampat, Komodo, and Bali, as well as dozens of lesser-known but equally fantastic sites. 

What sets Indonesia apart from other Asian dive destinations is the huge abundance and variety of marine life found below the waves. Warm waters and tropical reefs are home to over a quarter of the world’s fish species and at least 70% of all coral species. Cape Kri, in the country’s Raja Ampat archipelago, holds the record for having the highest marine biodiversity on earth!

For those with a passion for macro photography and muck diving, Lembeh Strait in North Sulawesi is generally regarded as the world’s best macro destination. Divers from around the globe flock to Lembeh in the hope of spotting incredible critters such as the hairy frogfish, flamboyant cuttlefish, rhinopias, harlequin shrimp, and the stunning mandarin fish.

Indonesia also boasts some excellent big animal diving with destinations such as the Derawan Islands and the Banda Sea drawing pelagics and sharks close to shore for some exciting underwater encounters. For a chance to spot some of the largest fish in the sea, Cenderawasih Bay on the eastern side of West Papua is famed for its resident whale shark population, while the island of Nusa Penida in the popular resort of Bali, has some great diving spots with manta rays and mola mola

Huge variety and choice

Covering an area of nearly 120,000 square miles in the Western Pacific Ocean, the Philippines is a nation of over 7,600 islands lying north to south just above the equator. Encompassing a vast range of environments and habitats, the Philippines offers divers endless subsurface and topside options.

Many of the Philippines’ best dive destinations are less accessible than those of neighboring Indonesia, however, this only adds to the appeal and sense of adventure experienced by those that visit. Sites are uncrowded and marine life is thriving, and whatever your passion the Philippines is sure to deliver. 

The Philippines holds its own when it comes to marine biodiversity, and the protected Tubbataha Reefs National Park is a fantastic destination for spotting a huge array of life, big and small. Another great area is Puerto Galera on the island of Mindoro, where divers of all abilities can explore dozens of sites and revel in the rich marine life at Verde Island. Anilao and Dumaguete are the Philippines ’ world-class macro destinations, and they rival Lembeh in Indonesia for their quantity, diversity, and quality of macro subjects. Also at Dumaguete, the phenomenal Apo Island provides a wide-angle perspective on the region’s exceptional and vibrant marine life.

Moving further north, the island of Cebu is famed for its whale shark encounters along the coast of Oslob, as well as the thrilling sardine run at Moalboal. And to top it all off, Malapascua Island off the northern tip of Cebu is one of the few places in the world that thresher sharks come in close to the reef. As if all this marine life wasn’t enough, Coron Bay on the eastern side of Busuanga Island offers some of the best wreck diving in Asia.

Exotic and exclusive

While less popular amongst divers than other Southeast Asian destinations, the diving in Malaysia still has a lot to offer those keen to explore and try something different - and Sipadan offers some of the best scuba diving in the world.

Separated by the South China Sea, Malaysia is split into two main landmasses, Peninsular Malaysia south of Thailand, and to the east, Malaysian Borneo. As with the county itself, the diving in Malaysia is very different in each region. Peninsular Malaysia offers comfortable conditions and easy tropical reef dives, while Malaysian Borneo is characterized by deep ocean pinnacles and dramatic big animal encounters

The best dive sites on Peninsular Malaysia run down the region’s east coast, from the Perhentian Islands and Redang in the north to Tioman Island close to the causeway connecting Malaysia with Singapore. The Perhentian Islands are a true tropical paradise; long white sandy beaches, stilted huts, and warm, clear water providing access to rich reefs covered in life. Islands such as Redang, Lang Tengah, and Tenggol tell a similar story, while Tioman also boasts some deep WWII wrecks.

Malaysian Borneo covers roughly a quarter of the island's northern reaches, however, some of Asia’s best dive locations are located off its northwest coast. One of the highlights is Sipadan, an iconic destination offering some of the world’s most rich and varied marine life along bountiful reefs and deep walls. Other exclusive resort islands around Malaysian Borneo’s coastline include Layang Layang, Lankayan, Mataking, and Labuan, all offering private access to exciting open ocean sites. It’s not uncommon to encounter sharks, game fish, and other pelagics on the outer reefs and walls of these remote islands.

  • How to dive Malaysia: Peninsular Malaysia is mainly explored from resorts, as are the private islands to the north of Malaysian Borneo. Sipadan is normally a liveaboard destination.



 New discoveries and wrecks abound

Located off the southern tip of India, and surrounded by the Indian Ocean, Sri Lanka’s 1,000 miles of coastline offer a huge variety of year-round dive opportunities in comfortable conditions. Sri Lanka has long been a destination on the topside travelers’ itinerary, however, it has only recently become a country of note for divers. As such, the diving infrastructure in Sri Lanka is less developed than other established destinations. The exciting element to this is that new sites, reefs, and wrecks are regularly being discovered, and marine life is in great health. 

The annual monsoon dictates which side of Sri Lanka is open for diving at different times of the year. On the west coast, newly discovered reefs around Kalpitiya and Negombo offer excellent inshore dives teeming with tropical species. Further south, the Galle area has some fascinating underwater topography and unique black coral formations.  

The draw for many divers is that Sri Lanka is emerging as an excellent wreck diving destination. Along both the east and west coasts, scores of shipwrecks in varying depths offer exciting diving suitable for all abilities. Colombo offers some of the best access on the west, while the world-famous aircraft carrier HMS Hermes is sunk off the eastern town of Batticaloa. Also on the east coast, Kalmunai and the natural harbor of Trincomalee are home to numerous military ship and plane wrecks, ripe for exploration.

Hassle-free fun for all

Located north of the equator at the center of the Indochinese Peninsula, Thailand’s 1,200 miles of coastline offer diving on both the east and west coasts. Hundreds of islands in the Gulf of Thailand and the Andaman Sea ensure a vast array of marine life is thriving in warm, comfortable waters.

Thailand may seem like the tried and tested dive destination, but it has maintained its iconic popularity for good reason. Easy to get to from all over the world, and with a reliable internal transport network, diving Thailand is easy and hassle-free, boasting a well-established infrastructure of resorts, liveaboards, and dive operators. 

Thailand has always been a popular choice for those looking to try scuba diving or take a beginner course. On the country’s east coast, islands such as Koh Tao and Koh Samui offer long stretches of white, sandy beach leading to clear, blue water, colorful reefs, and plenty of small fish life. Southwestern islands such as Koh Phi Phi are similar, while some of the less touristy islands like Koh Lipe feature stunning soft corals, plentiful turtles, and even the chance to spot a dugong. 

Further out in the Andaman Sea, the Similan Islands and Surin Islands are remote National Park areas featuring healthy, well-preserved reefs, a huge range of corals, and rich marine life big and small. On the eastern side of the country, the Gulf of Thailand offers destinations such as Pattaya with its excellent wreck sites and impressive corals, and Koh Chang National Marine Park.
