The Dive Sites -
‘Welcome to our underwater world’
....We’ll Take You There.
The 3 main dive destinations are: Koh Tao, Sail Rock and the Anthong National Marine Park. The sites are easily accessible from Koh Samui taking from 50 to 90 minutes from departure to arrival. Water temperatures average a warm 30 degrees, with good all year round visibility. Only during the Monsoon season, which usually runs from early November to mid December, does visibility and access to the sites become limited. Here are a few descriptions of some of the more well known dive sites, but there are a lot more to choose from, particularly around Koh Tao. The choice of dive sites is dependent upon prevailing sea conditions and relevant PADI course standards and requirements.
Green Rock Max Depth: 25m. Intermediate to Advanced
Green Rock, situated to the north west of the beautiful island of Koh Nang Yuan, is renowned for its stunning swim thru’s and overhands.
The boulder and rock formations of the site give an amazing underwater topography. The central pinnacle is only 1m below the surface but the site itself drops off to 25m.
You will find Blue Spotted Rays nestling under shelves, inquisitive White Eyed Moray Eels and also the infamous Titan Triggerfish, so keep a wary eye.
White Rock Max Depth: 22m. All Levels of Divers
White Rock is found just south of Koh Nangyuan and consists of a main granite pinnacle in shallower water and additional smaller pinnacles located to the west in deeper waters.
The site is abundant with Red Breasted Wrasse, Blue Spotted Rays and White Eyed Moray Eels. Keep any eye out for the smaller stuff here, you’ll be rewarded with sightings of Nudibranchs, colourful Wart Slugs and smaller Crustacean.
Red Rock / Shark Island Max Depth: 28m. All Levels of Divers
Called Red Rock by some, to complete the three colours of the Italian flag, (Green Rock, White Rock, Red Rock) and Shark Island by others, as the shape of the rock looks like a shark’s fin, this site lies just South East of Koh Tao.
The North of the site gives shallower coral gardens to around 12m, whilst further south you reach deeper waters of around 25m and find beautiful boulder formations.
Blue Ringed Angel Fish, Butterfly Fish and Parrot Fish are seen in abundance, and if you’re lucky you may see juvenile Black Tip Reef Sharks and the occasional Leopard Shark resting on the sand.
Twins Max Depth: 18m. All Levels of Divers & Snorkelers
As its name suggests you’ll find two distinct groups of pinnacles at this site. Twins is suitable for students and those more experienced. At the shallower pinnacles you will reach a maximum depth of 12m, whilst you can reach 18m at the second pinnacle.
White Eyed Moray Eels and Blue Spotted Rays can be found in abundance at both pinnacles, as can Red Breasted Wrasse, Blue Ringed Angel Fish and Banner Fish.
Depth and visibility permitting, you cannot visit Twins and not make a pilgrimage to the home of Nemo - just ask any of The Team!
Mango Bay Max Depth: 14m. All Levels of Divers & Snorkelers
Located on the North East coast of Koh Tao, this is one of the best sites for students and those divers who haven’t been in the water for a while.
The dive begins from the gentle sloping beach and follows the line of the rock along to a maximum depth of 14m.
The resident shoal of Yellow Fusiliers, accompanied by Yellowtail Barracuda, Giant Clams and rainbow coloured Christmas Tree Worms, make this a wonderful site to start to any diving adventure.
Aow Leuk Max Depth: 12m. All Levels of Divers & Snorkelers
Literally translated as ‘Deep Bay’ not because of its depth but because of the width of the bay, Aow Leuk is our other favourite site for students and those wanting a gentle potter.
Located to the south of Koh Tao, Aow Leuk like Mango Bay starts from the beach. You follow the Western wall out of the bay and find schools of Yellowtail Barracuda, paired Weavers Butterfly Fish and numerous Christmas Tree Worms.
Glide up into the shallows on your return to the beach and you may be lucky enough to see the resident turtle and find many Blue Spotted Rays.
Sail Rock Depth Range: 12 to 40m
A real open water site, Sail Rock can be found equidistant between Koh Phangan and Koh Tao. Not suitable for complete beginners, Sail Rock is considered to be one of the best sites in the Gulf of Thailand.
Comprising one large granite rock pinnacle, which stands 15m above sea level and drops off to a max depth of 30m and outer lying smaller pinnacles, it thoroughly deserves the 2 dives we make at the site.
The famous feature of Sail Rock is ‘The Chimney’ - a large vertical swim through which can be accessed at 5m, 12m and 18m. Inside you will find wonderful clam and coral formations, dancing shrimp and much more.
A full circuit of the whole rock takes approx 35 - 40 minutes & en route you will encounter mountain ranges, cascading coral gardens, vertical walls and delightful gullies.
The marine life at Sail Rock abounds, with the smaller coral fish - Blue Ringed Angel Fish, Banner Fish and Butterfly Fish to name a few, found closer to the rock. The larger pelagics - Chevron Barracuda, Whale Shark and Sail Fish - can be found cruising the deep blue, just out from the rock.
When conditions permit a whole dive can be made at The Secret Pinnacle which lies east of the main rock and delights with Giant Grouper, huge schools of Spanish Mackerel and Big Eyed Trevally.
The favourite site of all our dive team, Sail Rock deservedly maintains its position as the No 1 dive site from Samui.
Koh Yippon Lek Max Depth: 20m. All Levels of Divers & Snorkelers
Koh Yippon Lek - translates as “Small Japanese Island”. It lies at the northern most edge of the Marine Park and the site provides wonderful shallow caves and swim throughs.
Although visibility here is usually less than Koh Tao and Sail Rock, when diving well, you will be rewarded with Banded Seas Snakes, Squid, Cuttlefish and huge Barrel Sponges.
Koh Wao Max Depth: 18m. All Levels of Divers & Snorkelers
Coral fringes the shore line in this picturesque bay, carpeting the rocks from just below the surface to the sandy floor which starts at 5m and reaches 20m further out in the bay.
Heading around the western corner of the bay you’ll find a series of lovely overhangs and swim thru’s – watch out, some are quite narrow.
Juvenile Harlequin Sweetlips can be found if you look carefully along with Blue Spotted Sting Rays and Banded Sea Snakes.
