Discover One of the World’s Most Legendary Dive Sites

For passionate divers, few experiences compare to Day Dive Trips to Richelieu Rock . Located in the open sea of the Andaman, just north of the Similan Islands, Richelieu Rock is widely recognized as Thailand’s number one dive site – and for good reason. With its dramatic underwater scenery, dazzling soft corals, and extraordinary biodiversity, it offers something for every diver, from macro enthusiasts to those chasing the thrill of swimming alongside whale sharks.

A Journey with Wetzonedivers

Your adventure begins in the early morning, when Wetzonedivers collects you from your hotel and takes you to Baan Nam Kem pier. Here, you’ll board our comfortable diving speedboat, the “Blue Marlin,” where your equipment is already set up and waiting. After a light breakfast and a friendly boat briefing, we set course for Richelieu Rock. The journey takes about an hour, and as you cruise across the Andaman Sea, anticipation builds for the incredible dives ahead.

On arrival, your dive guide will brief you on the site and then it’s time to roll into the water.  

Day Dive Trips to Richelieu Rock typically include two unforgettable dives, with a relaxed surface interval in between, during which we serve a freshly prepared lunch. After the second dive, fruit and refreshments are provided as we head back to Khao Lak, usually arriving around 4 pm.

Why Richelieu Rock is So Special

Richelieu Rock isn’t just another dive site – it’s a living cathedral of marine life. Rising dramatically from the depths, the rock is blanketed in colorful soft corals and sea fans, creating a vibrant underwater tapestry. This thriving ecosystem is home to rare critters such as harlequin shrimp, ghost pipefish, seahorses, and nudibranchs, making it a paradise for underwater photographers.

At the same time, Richelieu Rock is famous for its pelagic visitors. Schools of barracuda, trevally, and mackerel swirl in dazzling formations, while giant groupers and moray eels patrol the reef. And for the ultimate encounter, lucky divers may find themselves face-to-face with a gentle giant – the whale shark – which frequents the site during the diving season.

Wetzonedivers ensures that every trip is not only exciting but also safe and well-organized. Our experienced dive guides know Richelieu Rock intimately and will lead you through its maze-like formations with confidence. Small group sizes mean you get personal attention, whether you’re logging your first dives in the Andaman or are a seasoned diver returning to a favorite site.
