The region of the Similan archipelago is the only place in the world where the transparency of the water is equal to the standard Red Sea and is 50 m. Thanks to this, divers can observe here all the splendor of the colors of the underwater world. It’s all about the volcanic origin of the archipelago and the absence of any unnecessary turbidity in the water. If you are interested, remember!
Richelieu Rock is the leader of the hit parade!

The walls are completely covered with soft corals, with a few spots of hard corals, giant sea fans and sea anemones.

How to organize a trip to Richelieu Rock
Since this is one of the world’s best dive sites and the main diving feature of the Similan Islands, it is better to plan in advance your trip during the high season. Ships go there strictly according to the schedule, one day is not enough for the trip.
When ordering a dive safari on South Siam ships, you do 3-4 dives a day, and spend the nights in an air-conditioned double cabin. There are 10-12 such cabins on ships. Toilets, showers (6 pcs.) Are shared and located on the main deck.
Also safari ships with cabins of both economy and premium class go to Similans. The duration of these safaris is 4-5 days.
Safari ships usually leave in the evening, and you meet the morning already at Similans.
The most expensive, but at the same time the most comfortable way to visit Similan is to rent a yacht, on which you can go to the islands directly from Phuket.
When to go
The largest influx of tourists is observed in Similan from mid-December to mid-January.
Some lull occurs from mid-January to mid-February and then from March to May.
