Dive & Sail Thailand: Similan & Surin Islands

March 2024

Starting at $8,995/person

Rich marine life, crystal clear waters, & white beaches

Set sail on our luxury vessel and dive into the natural beauty of Thailand. Located in the Andaman Sea in southern Thailand, the beautiful Similan and Surin islands are a scenic group of islands. Above the water topography is stunning; lush vegetation tops the islands giving way to granite boulders or white sandy beaches, surrounded by crystal clear water. But, it is what lies beneath the surface that allows the Similans and Surin Islands to lay claim to being two of the most famous scuba diving destinations in the world.


Immerse yourself in colorful reefs, lush corals, impressive sea fans and an incredible variety of marine life including whale sharks, giant oceanic manta rays, leopard sharks, green turtles, and hawksbill turtles.


This idyllic tropical setting, as well as the exciting and varied diving opportunities, make this a perfect vacation and diving trip. Click here to register your interest.

Richelieu Rock

Day 4

​This limestone pinnacle was named by Jacques Cousteau after General Richelieu, who was an important Danish officer in the Thai Navy. There are gorgeous purple dendronephthya soft corals covering most of the pinnacle and other areas covered in magnificent sea anemones as well. This site offers great diversity for such a small and isolated spot. It also offers excellent multi-level diving and because it is a high-profile reef, there are always sheltered areas to hide from current. The marine life is prolific and includes amongst, many other things; Pharaoh cuttlefish, large octopi, all 5 varieties of anemonefish of the Andaman Sea, a variety of moray eels, tiger tail seahorses, and occasional sightings of manta rays and whale sharks.

What's included: Onboard cabin, breakfast, lunch, dinner.

Surin Islands

Day 5

​Topside scenery of Koh Surin with evergreen forests, mangroves and small beaches surpasses even that of the picturesque Similan Islands. Under water the reefs of Surin have the greatest hard coral diversity in Thailand. You are likely to see Napoleon wrasse, yellow-masked angelfish, bumphead parrotfish, tomato anemonefish as well turtles that still come ashore in this area to lay their eggs.
