Southeast Asia is arguably home to the best diving on Earth. Flourishing coral reefs, jagged rock formations and sheer underwater walls that drop off into open water attract tropical fish and pelagics of all kinds. A liveaboard trip is hands-down the best way to experience this diving mecca.
The Coral Triangle encompassing Indonesia, Malaysia and the Philippines is known to have the richest marine biodiversity on the planet, with over 2000 fish and more than 500 species of coral. Further to the west, the Mergui Archipelago and the Similan Islands offer exhilarating diving with rare marine creatures of their own. Wherever you go in Southeast Asia, you can be assured of an unforgettable dive vacation.

With a trip on the only Sipadan liveaboard, scuba divers are assured one of the coveted permits to dive this protected area.
Just off the shore of Malaysia’s only oceanic island, a steep wall covered in coral plunges 600m down into the seabed.

The remote Mergui (or Myeik) Archipelago comprises 800 islands off the Burmese coast. Mergui is a protected area, and in recent years the government has made an effort to curb invasive human activity in the region. In terms of diving it is relatively unknown, meaning that with a Mergui liveaboard you’ll be one of few with access to the dive sites.
Day and night, amazingly uncrowded waters attract a plethora of marine life including barracudas, tuna and lobster as well as the less common bowmouth guitar fish. Whale sharks and manta rays can be glimpsed in the open water next to the deeper seamounts. Deep dive sites, drop-offs and harsh currents make the Mergui Archipelago a good choice for advanced divers.

Situated in the heart of the Coral Triangle, 81 miles off the coast of Palawan, Tubbataha Reef is one of the oldest ecosystems in the Philippines. The waters are crystal-clear and whales and dolphins can be seen even from above the water. Because of its isolated location, the only way to reach the area is with a Tubbataha liveaboard.
Tubbataha Reef offers incredible diving with an abundance of marine life. A 100m-deep coral wall hosts angelfish, barracudas and Napoleon wrasse, while large pelagics such as manta rays and schooling hammerhead sharks lurk in the deep blue ocean just around the corner. There are several small wrecks, and night dives afford the opportunity to spot moray eels and pufferfish.
