Best diving destinations in Asia

Deep sea drop-offs and tropical marine sanctuaries across Asia

Southeast Asia holds some of the most biodiverse reefs on earth, regularly cited by marine biologists as having more coral and fish species than anywhere else in the world. Neighbouring countries add their own celebrated wreck and reef diving traditions.

The destinations on this list range from remote liveaboard-only reef systems to shore-accessible dive resorts built specifically around a single famous site. Visibility and current strength vary considerably by season and location across the region.

Choosing the right season matters enormously here, since monsoon patterns affect visibility and safe conditions differently across each country's coastline. Many liveaboards also include marine biologists or experienced dive guides on board. Booking dives through operators with strong safety records also matters considerably, particularly at sites with stronger current.
