Scuba Diving in Asia

Southeast Asia boasts exquisite coral reefs, diverse marine life, whales, sharks and wrecks for divers to discover! There’s something here for every diver!

The Similan Islands are best-known for their whale shark encounters off Oslob’s coast, yet also offer year-round sightings of manta rays and black-tip reef sharks – making this an excellent option for advanced divers!


Philippines are a tropical country known for their warm waters and diverse marine life, making diving year-round possible here. To maximize diving conditions during this whale shark season (November through May), however, the optimal time to visit is from November through May when amihan monsoon brings dry weather and calmer seas – it makes diving even easier in these conditions!

Puerto Princesa on Palawan island serves as the primary starting point for scuba diving in the Philippines, offering access to some of the best diving sites across the nation – Coron Bay being among them – featuring almost intact World War II shipwrecks now covered with corals, gorgonians and purple sea fans – which make for spectacular dives.

Tubbataha Reef Natural Park, only accessible via liveaboard and widely considered one of Asia’s premier dive sites, should not be missed. This isolated, 100,000 hectare UNESCO World Heritage site hosts an abundance of marine species such as manta rays and whale sharks; photography enthusiasts will also love photographing here as it boasts numerous schools of fish; it’s also great for seeing large pelagic fish such as barracuda or jacks!

Other top diving spots in the Philippines include Maya Port on Dumaguete Island, which is famous for muck diving and macro photography. Here you can spot nudibranchs, pipefish, dragonets, blue-ring octopus as well as an abundance of corals. Additionally, its steep walls may prove challenging.

Diving in the Philippines is safe, and there are plenty of quality dive shops. As with most destinations in Southeast Asia, it is wise to do your research and select a reputable company who takes all necessary safety measures into consideration when operating their dive shop. Ideally only dive with those accredited by The Philippine Commmission on Sport Diving as this will give you additional peace of mind that they have your safety covered.

When diving in Asia, it’s essential to follow good safety practices and listen to your body. Avoid diving if you feel unwell or fatigued; inspect equipment prior to each dive to make sure everything works as it should; do not dive with an air tank that is empty or near empty; call the DAN Emergency Hotline if something arises while diving; this membership provides invaluable help and protection should any emergencies arise while underwater.

Notable activities in Indonesia outside of diving include land-based tours to see Komodo dragons, nature trips that showcase incredible birdlife, and visiting Aboi hill tribe village on Alor. Non-diving/snorkelling passengers are generally welcome on most liveaboard cruises; however their prices may be slightly higher since their cabin could otherwise have been filled by paying divers.

Timor-Leste (commonly referred to as East Timor) may not immediately come to mind when you consider diving destinations, yet every diving enthusiast should put it on their bucket list. One of the newest countries and still relatively off the tourist radar, Timor-Leste offers stunning beaches, unspoilt rainforest and some of the best diving experiences available anywhere on Earth.

At the southwest tip of the Coral Triangle lies an oasis of warm waters free from commercial fishing or heavy industry that draws some of the best dive operators worldwide.

Timor-Leste is a developing country and as such there may be restrictions to what divers can expect. For this reason, it is wise to secure medical expenses coverage while ensuring their trip includes a registered local dive operator. Furthermore, US dollars and travellers cheques should also be carried for convenience when making this trip.

Keep in mind that although the political situation in Timor-Leste has improved significantly since gaining independence in 2002, there may still be security concerns. Before booking your travel plans to Timor-Leste it would be prudent to contact the Foreign Office.
