Koh Samui Dive Sites

Scuba Diving in Koh Samui

The waters around Koh Samui are teeming with a wide range of fish such as tuna, red snapper, barracuda and mackerel. You will also come across whale sharks, giant groupers scribbled filefish and yellowtails amongst others.

All in all, you'd be hard pressed to find better sites within short distance of each other and visibility is generally excellent. Coral, too, is in abundance, making a day or two out diving an attractive and rewarding holiday experience. It's no coincidence that many people head to picturesque Koh Tao (Turtle Island) to learn to dive. The island's Japanese Garden dive site ranks highly in the world's 'Best Dive Sites' list.

Koh Tao Dive Sites

About 70 Km north of Samui is the island of Koh Tao (Turtle Island). There are numerous dive sites in and around Koh Tao, which is is a mini-tropical paradise offering jungle walks and white sandy beaches. Here the water visibility ranges from 15-30 meters and includes the popular dive spots of Chumporn and Southwest Pinnacles, Nang Yuan, Green Rock, White Rock and Red Rock. The waters around Koh Tao are home to an abundant range of marine life, including barracuda, tuna, snapper and sea turtles.

Chumporn Pinnacles

Considered one of the more challenging dive sites with occasionally strong currents and depths of 10-35 meters, this site consists of fascinating submerged pinnacles. The highest of these rocks is approximately 16 meters below the surface. At Chumporn, you can swim with man-sized groupers and other large pelagic fish, including schools of barracuda, tuna and mackerel. Read More...

Green Rock

Green Rock provides a good selection of swim-through opportunities in depths of 4-25 meters. The rock consists of large archways, caverns, caves and crevices. Common sightings include harlequin sweetlips, blue-ringed angelfish and moray eels. Sometimes you can spot whitetip reef sharks, and further out in deeper water, large groupers, schools of yellowtail, fusilier and silver fish.

Hin Wong

Located east of Koh Tao, Hin Wong is a large and varied site, with depths ranging from 10-30 meters. Unfortunately, the only shortcoming of the site is the unpredictable water visibility, which cannot be assured at all times.

Nevertheless, the site abounds with delicate sea fans and spiraling wire coral and is home to many types of fish including groupers, filefish, snapper, etc. If you are lucky and keep your distance, you may even see sea turtles feeding off the rich variety of food the reef has to offer.

Samran Pinnacles

This dive site tends to attract the more advanced diver as the water is deeper and the currents are certainly much stronger. The rocks are submerged in 12 meters of water and attract large schools of jackfish (bigger varieties), trevally and giant barracudas.

Southwest Pinnacles

The Southwest Pinnacles consist of three rock formations which range from 4-30 meters below the surface, representing a series of short wall dives. At the top of the pinnacles are blankets of underwater plant life in a stunning array of rainbow colors. Between the rocks are many bushy black coral sea whips and gorgonian sea fans. Read More...

White Rock

This dive explores two submerged pinnacles which are only two meters above the surface but extend between 18-22 meters underwater. Schools of butterfly fish and angel fish predominate and colonies of staghorn corals attract breams and damsels to make their homes here. On any given dive look out for the more exciting sightings of sea snakes, turtles, morays and blue spotted stingrays. An interesting and equally exciting part of your dive will hopefully be an encounter with White Rock's resident titan trigger fish -- territorial by nature and supremely erratic.

North of Samui between the islands of Koh Tao and Phangan is the internationally renowned dive site of Sail Rock. Although only 15 meters above the water, the structure extends 40 meters below the surface. The main attraction of Sail Rock is a naturally formed 15-meter high underwater dive wall or chimney.
