Richelieu Rock

The most famous dive site in Thailand has to be Richelieu rock. It is an isolate pinnacle in a horse shoe shape. When it reaches low tide you can, just make out the top of the pinnacle.  In Low tide Richelieu Rock is total submerged in the Andaman sea. This usual horse shoe shape hides a multitude of marine life.

First dive on Richelieu rock

The first dive is always the deepest. So when diving here, you will dive the outer side of the horse shoe first.  There are many smaller rock formations here. One is called the telephone box. Maximum depth here is 35 meters. This is a great place to found sea horses. There is   always one that hides, its self behind the sea fan. As you shallow up, there, is a ledge or alcove at 20 meter. Sometime you can find ghost pipe fish here. The most important thing about Richelieu rock is – keep your eyes and ears open, for the unexpected. If you hear a loud noise, banging on tanks. Look up immediately. That sound is an Instructor or dive guide telling you. There is a whale shark about.

Don’t be disappointed. If you don’t get to see a whale shark. There is so much more to Richelieu rock then a whale shark. The diversity of marine life here is amazing.

Second dive at Richelieu rock

This time you will dive the inner side of the horse shoe. There are lots of craves to search out. There is usually a group of mating cuttlefish there.

At 15 meters there are harlequin shrimp in a small hole. You will know they are there. Because there will be a, blue sea star outside the entrance. Harlequin shrimp love to eat away on the live sea star.
