The legendary pinnacle — one site, endless surprises
Every Wednesday & Sunday
Richelieu Rock is famous for a reason: it’s one of the most concentrated, high-energy dives in the region. A huge pinnacle rising out of open sea, it can deliver everything in one place — big pelagic potential in the blue, incredible reef color on the rock itself, and small hidden treasures for anyone who likes to look closely. It’s a dive people plan their whole trip around, and even after you’ve done it once, it never feels “done.”
Because Richelieu sits exposed with no sheltered moorings, it has a true expedition vibe — conditions can be sporty, and that water movement is exactly what brings the action. With an experienced guide and a solid briefing, you learn how to enjoy it comfortably and intelligently, using the structure of the pinnacle to find shelter and the best viewing angles. If you want the most iconic Andaman dive in your week, this is it — and if you’re lucky enough to get great conditions, it’s the kind of day you’ll talk about long after your holiday ends.

Tour Location
Similan Islands #4 & #5 – Similan National Park
Similan Islands #4 and #5 are part of Mu Ko Similan National Park, one of Thailand’s most famous protected marine areas. These islands are known for their bright, shallow reefs, calm bays, and that classic Similan scenery: turquoise water, white sand, and smooth granite rocks along the shoreline.
Underwater, the area is a beautiful mix of coral gardens and rocky reef formations. It’s a great place to enjoy relaxed dives and snorkeling, with colorful reef fish everywhere and plenty to look at even in the shallows. On many days you may spot turtles cruising through the reef, along with schools of fish moving over the coral and rocks.
