Southeast Asia's Best Dive Sites

Southeast Asia is home to the Coral Triangle — the most biodiverse marine region on Earth. From beginner-friendly reefs to world-class deep dives, there's something for every level.

Thailand

Koh Tao

The world's scuba diving capital. Affordable courses, warm water, and a huge choice of dive schools. Best sites: Sail Rock, Chumphon Pinnacle, Japanese Gardens.

Similan Islands

Seasonal (November-May) but spectacular. Granite boulder formations, manta rays, and whale sharks. Liveaboard trips recommended.

Koh Lanta / Phi Phi

Accessible from Krabi, great for combining diving with beach holidays. Leopard sharks at Hin Daeng/Hin Muang.

Indonesia

Raja Ampat

The crown jewel. Highest marine biodiversity on Earth. Remote and expensive but absolutely worth it for experienced divers.
