Destinations
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. Frequently visited for deep dives in the morning, west sides of the islands offer dynamic rocky formations.
Some boulders 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. Some of them are very unique which can be sighted only in the area, very different from the other side of Malay Peninsula or Pacific Ocean. 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.
Visibility: 20-40 meters+
Depth: 5-40 meters
Current: mild – very strong

Richelieu Rock is known as one of the world’s best place to swim with the Whale Shark. The top of this dive site is barely exposed only when low tide but with or without the shark, the vibrant underwater life and generally good visibility makes this dive site very popular. Koh Tachai is also known for large creatures and common but rich marine life.
Visibility:15-30 meters+
Depth: 5-35+ meters
Current: mild – very strong
Diver Level: advance and above
Koh Bon as well as some of the dive sites in the Similans is known for Manta Rays encounter, where you might spend most of your bottom time with multiple mantas. The island also offers a great wall dive where leopard sharks and nurse sharks are common. Koh Bon’s West Ridge is one of the few sites in the region where it dramatically drops down to 30 meters+ in depth.
Visibility: 15-30 meters+
Depth: 10-35+ meters
Current: mild – strong
