Sites Visited:


Sail Rock-This dramatic rock rises out of the water creating the best wall dive in the Gulf of Thailand, with a maximum depth of 40 meters. You will find the wall covered in sponges along with many oysters and clams clinging to the craggy surface. Most divers come here in the hope of seeing whale sharks, which are frequently sighted in season, whilst the rest of the year divers swim surrounded by schools of pelagic fish patrolling the depths. The site is best known for it’s naturally formed rock ‘chimney’ where you can enter an opening at 18 meters and ascend inside the rock and exit at 10 meters.

Ang Thong National Marine Park - Made famous in the recent novel and film ‘The Beach’, this beautiful group of islands has some of the most impressive land scenery in SE Asia. These dive sites are renowned for their variety of soft corals, fascinating underwater caves and swim thru’s. Here you will be amazed by the diversity of marine life, the sites are also ideal for snorkeling and swimming.

Koh Tao - This small island boasts around 20 excellent dive sites. World class diving can be found at Chumporn & South West Pinnacles. Other Popular sites include Shark Island with its diverse range of coral and marine life, White Rock with its Trigger Fish and Turtles and the exciting swim thru’s of Green Rock.

Koh Nang Yuan - Located just off Koh Tao this small island consists of three rocky outlets, connected by three white sandy beaches. Here you will find three bays with sloping reefs going down to a maximum depth of 14 meters, which are ideal for snorkeling and diving. You will find all kinds of coral including, lettuce coral as well as stag horn, and tabletop and cauliflower corals. Among the many varieties of reef fish living here are parrotfish, bird wrasse, butterfly fish, small yellow tail barracuda and honeycombed grouper.

Shark Island - Located just of the South coast of Koh Tao this twin rock outcrop consists of a steeply slopping reef going from 4 meters down to 20 meters. One of the biggest attractions of this dive is the variety of corals and fish life to be found. On the East side of the rock you will find a slopping reef covered in brain corals, vivid pink anemones and large barrel sponges, among the corals you will see snappers, banded angel fish and blue spotted stingrays.

This site is also ideal for novice and experienced divers and offers great snorkeling.

Chumpon Pinnacles - Located North West of Koh Tao, this group of completely submerged pinnacles is probably one of the best dives in the Gulf Of Thailand and is not to be missed. The giant rock pinnacles rise up from 35 meters to 14 meters and are covered in a carpet of pink anemones. The main attraction for many divers is the massive groupers that can be seen on most dives hanging in the current just off the pinnacles. Here you will also have an excellent opportunity to see the illusive Whale Shark, which often cruises by followed by, great barracuda, jacks, tuna and shoals of Bat fish.

Green Rock - Lying to the North of Koh Nang Yuan this site is famous for its numerous swim-throughs, caverns and overhangs. Descending down the Northern most buoy line to 18 meters you will find the nesting ground of the infamous Triggerfish, in season sometimes there will be up to 20-30 of them. Triggerfish are beautiful creatures however in season some species are extremely territorial, so divers beware.
