Dive Sites Information
The Similan Islands Lying north to south approximately 100km north of Phuket, consist of 9 islands and surrounding dive sites. On the east sides are beautiful white powder-sand slopes dramatically dropping from the beaches, some up to 30 meters or deeper, some covered with massive healthy coral reefs.
Try to count how many kinds of butterfly fish you can spot in one dive and meet various cousins of Nemo. Leopard Sharks and reef sharks, great barracudas are commonly seen in the morning dives and colorful reef fish, small stuff and occasional Napoleons are dwellers in the afternoon dive sites.
Frequently visited for deep dives, the west sides of Koh Bon offer dynamic rocky formations, rise from the bottom (30M or deeper) straight up to above water creating very exciting underwater landscapes for you to explore. Since the Similan Islands are one of Thailand’s National Parks, marine life are well protected and boast great variety.
- Visibility: 20-40 meters
- Depth: 5-40 meters
- Current: mild – very strong
- Diver Level: advance and above, partially suitable for beginner
Richelieu Rock is known as one of the world’s best dive sites. The top of this dive site is barely exposed only when low tide but with or without sighting of the whale shark, the vibrant underwater life and generally good visibility makes this dive site very popular.
It takes normally 4-6 dives to truly appreciate this spectacular and iconic purple rock, discovered for recreational diving by Jaques-Yves Cousteau in 1989.
- Visibility: 10-40 meters
- Depth: 5-35 meters
- Current: very mild to strong
- Recommended Diver experience: Advanced certified with competent buoyancy control and ability to handle moderate to strong current
Koh Tachai is well known for large fish sightings over the last few years. Since 2014, whale sharks and oceanic manta rays return frequently to this strong current driven pinnacle. Since the Marine Park closed the beach on this island from non-diving day tours, the richness of fish life had increased exponentially.
- Visibility: 10-30 meters
- Depth: 10-30 meters
- Current: moderate to very strong
- Recommended Diver experience: Advance certified with competent buoyancy control, good air use and can handle strong current.
Koh Surin Marine Park is the lesser known jewel of Thailand West Coast, Surin Islands offers amazing reef structures, coral gardens and beautiful topside views. Thanks to the Similans taking all of the notoriety, Surin continues to be a hidden gem for divers, with healthy reef and abundance fish life. Conditions are easy to moderate, and perfect for beginner to advance level divers.
The resident marine life includes turtles, schooling of yellow-lined snappers, jacks and barracudas. You also will find some reef fish common only in this area such as Blue ring Angel Fish. Extra encounter on a dive is seasonal whale sharks and small stuff like seahorses and ghost pipefish.
