Richelieu Rock, Koh Bon, Koh Tachai... Dive the Best of Thailand

Why we love it

The Surin and Similan Islands, north west of Thailand host some of the best dive sites in the world. Diving Richelieu Rock, its most famous site, feels like being in a big aquarium filled with lots of tropical fish. Keep your eyes open as while we were diving there, we almost missed a whaleshark because we were just too busy looking at some macro! Big and small you have it all. A perfect dive trip for people who just have a few days, with lots of action and an amazing crew.

Conservation

The boat runs cruises to remove abandoned fishing nets and lines with Ocean Quest Global in Myanmar, and expeditions with Manta Trust and others to identify whale sharks in Thailand (see dates in our "What's Included" section). Longitude 181 Member. Reef-friendly toiletries on-board.

Who is it for?

For both new and advanced divers who like variety. Drift dives, night, deep and shallower dives. Other activities: kayak, islands exploration, eating great food on board, chill out in between dives!
