Sail Rock

Location: Between Koh Tao and Koh Phangan
Depth: Average 18 m / Maximum 40 m
Level of Diving: Beginner to Experienced Divers

Sail Rock can be easily located in the Gulf as it is an impressive pinnacle that breaks the surface. A great way to begin the dive is to enter through the magnificent chimney at around 4 m that then presents an exit at a depth of 18 m. Keep your eyes peeled for an encounter with a giant green moray eel and clustering coral banded shrimp. An easy dive site to navigate by circling the rock formation, you may also come across pelagic fish such as a whale sharks. We visit Sail Rock every Thursday for a day trip from Koh Tao. Sign up for your Open Water Diving Course on a Monday to end your course on a Thursday at Sail Rock.

Southwest Pinnacle

Location: About 7 km Southwest of Koh Tao
Depth: Average 17 m / Maximum 28 m
Level of Diving: Beginner to Experienced Divers

A row of pinnacles offering wall dives and fantastic schooling marine life, such as snapper, trevally, and barracuda. The shallower points are carpeted with gardens of sea anemones and the deeper gullies are filled with healthy gorgonians and whip corals. This is one of our favourites Koh Tao diving sites, however it’s often difficult to access due to winds from the southern side of the island.

Chumphon Pinnacle

Location: About 5 km northwest of Nang Yuan
Depth: Average 20 m / Maximum 36 m
Level of Diving: Experienced Divers

This deep pinnacle is typically reserved for Advanced divers, but can be accessed on your final open water training dives in good conditions. Majestic views, breathtaking rock formations and large marine life, with the increased chance of whale shark sighting. We visit Chumphon Pinnacle 3-4 times a week and it’s a great way to finish your Open Water Course on Koh Tao with two dives here.

Koh Tao diving sites - Shark Island

Shark Island

Location: 1 km off the southern tip of Koh Tao
Depth: Average 15 m / Maximum 28 m
Level of Diving: Beginner to Experienced Divers

Shark Island is named not for its carnivorous marine life but for the island’s resemblance to a shark fin from certain angles. The occasional currents bring in nutrient rich waters encouraging an abundance of marine life. Groupers, turtles and schools of raccoon butterfly fish inhabit the shallower depths, and nudibranch nurseries line the eastern coast.

White Rock

Location: Western side of Koh Tao
Depth: Average 16 m / Maximum 28 m
Level of Diving: Beginner to Experienced Divers

White Rock is one of the most popular Koh Tao diving sites for both day and night dives. It is home to the titan triggerfish, some of which occasionally act quite aggressively. The rock structures are a number of elevated shelves that provide shelter for honeycomb groupers, long-spined black sea urchins and various sea anemones, along with the soft coral mix with knob and pore corals and the colourful christmas tree worms. If you enjoy underwater photography then this dive site provides the composition, and marine life for great pictures. We always dive here during our Open Water Courses.

Twins & Bouyancy World

Location: Western Side of Koh Nang Yuan
Depth: Average 10 m / Maximum 18 m
Level of Diving: Beginner to Experienced Divers

Scattered around the three rock pinnacles, you will find numerous black sea cucumbers, boulder corals and Neptune barrel sponges covered in long white alabaster tubeworms. In between two of the shallow pinnacles (12 – 14 m) you will find the Clarks anemone fish family protected by a ring of shells. Off to the north of the middle pinnacle you will find Buoyancy World, an ‘alternative’ dive site to help lessen the number of divers at Twins – which is great for the buoyancy dive during the Advanced Course. Here you will find man-made structures built from materials that will attract fish life and coral development along with buoyancy structures used for novice divers to enhance their diving skills.

HTMS Sattakut

Location: 30 m from Hin Pee Wee
Depth: Average 18 m / Maximum 30 m
Level of Diving: Experienced Divers

The HTMS Sattakut (LCI : Landing Craft Infantry 724) shipwreck has become a favourite dive site for visitors to Koh Tao. This former US World War II Navy vessel that runs 48 m in length along the sea bed was sunk on the 18 June 2011 to create a new artificial reef. As a US Navy Ship the Sattakut participated in the Battle of Iwo Jima, one of the most strategic battles between the USA and Japan during World War II. We always visit this awesome dive site during our Advanced courses – unfortunately it’s a little too deep to visit during the Open Water Course.

The wreck’s keel or base sits in the sand at a maximum depth of between 27 and 30 metres while the top of the mast reaches to a depth of 18 metres – making this dive most suitable for divers with the Advanced Open Water certification. She lies 30 m from Hin Pee Wee thereby providing a complimentary dive site offering an abundance of marine life nearby. Here you will find large schools of fusiliers, juvenile yellowtail barracudas, various snappers, wrasse and groupers.

Green Rock

Location: North-West of Koh Nang Yuan
Depth: Average 12 m / Maximum 30 m
Level of Diving: Beginner to Experienced Divers

A spectacular dive site offering adventurous swim-throughs provided by large archways, caverns, caves and crevices which cut through the submerged, bouldering rocks.

Home to the yellow margin triggerfish, divers may encounter a ‘trigger- attack’ during the spawning season, as they become very territorial and protective over their nests which makes for an interesting dive.

Red Rock

Location: North-East of Koh Nang Yuan
Depth: Average 12 m / Maximum 20 m
Level of Diving: Beginner to Experienced Divers

Nicknamed ‘Red Rock’ – a pinnacle that stems from 18 m to just below the surface shelters stingrays, turtles and scorpion fish in the crevices formed through erosion over decades. Taking a heading of 240 degrees, toward the coast of Nang Yuan, you may encounter the infamous titan triggerfish that lingers at the base of a cave opening. This narrow cavern may be explored at the depths of 12 m. Prior to entering be aware that training in cavern diving is necessary for this penetration.

Mango Bay

Location: North of Koh Tao
Depth: Average 5 m / Maximum 16 m
Level of Diving: Beginner to Experienced Divers

A breeding ground for all small fish, Mango Bay (Aow Muang) has reefs on the east and west coastlines of the bay, along with coral boulders in between providing a natural ‘coral garden’ as we know it today. This bay is perfect for snorkellers and beginner divers to gradually make the transition from shallow sandy topography to deeper depths with rocky contours. Many operators from neighbouring islands visit Mango Bay for its beauty and pristine conditions.

Koh Tao diving sites - Japanese gardens

Japanese Gardens

Location: East of Koh Nang Yuan
Depth: Average 6 m / Maximum 16 m
Level of Diving: Beginner to Experienced Divers

Located on the east side of Koh Nang Yuan, Japanese Gardens is separated by one of the world’s only sandbars connecting three teardrops of land. Fantastic snorkeling and great conditions for beginner divers, this dive site offers sandy bottoms to prepare initial divers adjust- ing their buoyancy prior to venturing to the reef areas. The reef dive itself is incredibly beautiful, home to many juvenile fish including blue-ringed angelfish, moon wrasse, damsel and chromis fish with multiple porcupine pufferfish hiding within the crevices. On some occasions you may spot the black and white banded sea snake.

AWESOME DIVE SITES. 18 months ago I did my Open Water here and just returned to do my Advanced and fun dives. All the team are friendly and very accommodating to nervous divers. Really enjoyed my fun dives here exploring stunning dive sites with beautiful sealife in mostly excellent diving conditions. Special thanks to Franco for today’s amazing dives, excellent navigation and for taking the time afterwards to explain everything we saw in detail. Will definitely be coming back on my next visit to Koh Tao! 🙂

OPEN WATER & ADVANCED. In a week time me and my friend completed both the open water course and the advanced adventurer course. For both koh tao diving courses our instructor was Fabian, the best and nicest instructor we’ve ever met. The courses were organized perfectly and the dive sites we went to were amazing. We highly recommend to do your diving courses at Phoenix Diver Koh Tao

GREAT DIVING SCHOOL AND DIVING COURSE. I did my open water dive course with Phoenix Divers and had an amazing time in and out of the water. I had previously done a fun dive in Australia and hadn’t really enjoyed it but the open water course with Phoenix completely changed my opinion of diving. I had a great instructor (Nui) who catered for everyone’s ability, was very informative and had a great knowledge of Koh Tao’s dive sites. James and Jojo in the office were also very helpful in organising the course and other fun dives I did.

What’s also really good about Phoenix is that your time with the crew does not stop once your diving is done for the day. They are very keen to host you for sunset beers and games of pool after the day is over.

Would recommend Phoenix divers to anyone looking to do some diving in Koh Tao.
