There are two main dive destinations from Koh Samui: Sail Rock which is the closest and arguably the best site in the area and Koh Tao which has a number of dive sites ideal for all levels of diver. Below are details of the most popular sites.
Approximately 50 minutes speedboat journey north from Koh Samui, between Koh Phangan and Koh Tao, Sail Rock is a pinnacle shaped like an iceberg that rises out of the water creating a fantastic wall dive.
Sail Rock is stunning at depths of 5 metres and down to a maximum depth of 40 metres, so it is ideal for beginners and experienced divers alike. There are sometimes relatively strong currents on parts of the site, but the site is big enough for you to dive and avoid the current.
Sail Rock is famous for the vertical “Chimney”, which begins at around 16m and opens at the top around 6m and is great fun to ascend through – it is nice and wide with lots of light so you are not in a closed, dark hole! Sail Rock is one of the main sites in the area for sightings of Whale Sharks, but if they aren’t around there are always schools of Barracuda, large schools of Yellow Fusiliers, many schooling Trevally, Giant Morays, Large Groupers, Batfish and a great variety of other fish.
If you haven’t dived for a while and would like to go to Sail Rock we would recommend taking the PADI Reacivate Program a day or two before to make you more comfortable and help you enjoy this amazing site easier.
Koh Tao is approximately 1 hour 20 minutes speedboat journey north of Koh Samui. There are around 10-15 regularly dived sites ranging from shallow sites for complete beginners and students taking courses to sites for more experienced divers to enjoy easy, relaxing dives. All of the sites offer a fantastic variety of diving experiences.
Below are details of some of the main dive sites we dive around Koh Tao:
Located approximately 7 minutes speedboat journey from the north end of Koh Tao, Chumporn Pinnacle is regarded as the best dive site around the island.
The site consists of four interconnected, underwater pinnacles, which start at 14m below the surface and drop down to the bottom at about 36m. Because of the depth of the dive site, Chumporn Pinnacle is suitable for Advanced divers and divers that are comfortable in deep water that are looking to increase their experience.
Whale Sharks are often seen at Chumporn Pinnacle as well as Barracuda, schools of Snapper, Fusiliers, Batfish, Groupers and lots of Pink Anenome fish in the anenomes covering the top of the pinnacle.
Mango Bay is one of the most beautiful bays around Koh Tao. It is a perfect site for beginners and students, and is also ideal as a second dive for those who have had a deep first dive. The bay also provides an excellent location to do a number of Adventure dives. It is usually the first destination for customers joining us for our VIP Snorkel Tour to Koh Tao.
Along the reef barracudas, groupers, fusiliers, blue spotted stingrays, moray eels, angelfish and butterflyfish can be seen! And the occasional Seahorse can be spotted away from the reef in the sand.
The resident clark’s anemonefish family, protected by a stone ring around the anemone, is one of the highlights that helps make this site so popular. Also stingrays, moray eels, juvenile angelfish, groupers, wrasse and rabbit fish can be seen in abundance.
To the north of the dive site there is an area called Bouyancy World which consists of a number of obstacles placed in a position away from the reef that is ideal for beginners and Advanced students to practise their bouyancy wothout having to worry about damaging the reef.
Green Rock is on the north west tip of Koh Nangyuan and consists of boulder formations that form a number of swimthroughs. The deeper parts of the site go down to around 28m and beginners and students can stay in the shallower waters alongside the island at around 10m.
You will find parrotfish, white eyed morays, blue spotted stingrays and angelfish. You can also see green turtles and a number of yellow-margin and titan Triggerfish, nesting in the sandy areas around the rocks.
