Koh Tao Diving - Sail Rock

Sail Rock (‘Hin Bai’ in Thai) is the premier scuba diving site in the Gulf of Thailand. Situated an hour and a half boat ride from Koh Tao, we offer this popular dive site as a full day trip.

Sail Rock rises up 8m out of the water and the dive site has a maximum depth of over 40m. The actual rock wall drop down to below 20 metres, where it meets sand that gradually banks away.

There is a second large rock – that doesn’t reach the surface – on the south east of the dive site that drops down into the sand at more than 30 metres. Several smaller scattered rocks surround the main rock.

As Sail Rock is far away from the islands, it is a haven for marine life. Huge schools of Chevron Barracuda, smooth tailed Travelly and Queenfish hang just off the Pinnacle and you will often see solitary Great Barracudas circling, slightly off the pinnacle, just into the blue waiting to pounce on unsuspecting prey.

The dive site is abundant with colour and diversity; Schooling Long Fin Batfish, Giant Grouper hiding under overhangs and of course during season Whalesharks often feed here.

Sail Rock is unique as it gives you the opportunity to descend (and ascend should you wish to) actually inside the rock! Boasting a vertical like swim through, known as “the chimney”, this presents a cool buoyancy challenge for advanced divers. You enter at 5m – in single file – and descend down to 18m where you exit.

You can see a variety of fish, including soldier fish and blue spotted trout hiding out in the shadows of the Chimney and as you exit you should see an extremely inquisitive Giant Moral Eel just outside. Boasting scorpion fish amongst the mixed hard corals covering the rocks and ledges, Sail Rock offers plenty for macro enthusiasts including shrimps, crabs and Nudibranch.

Our Sail Rock day trips are extremely popular with our certified divers and include two dives on the gulf of Thailand’s premier dive site plus a Thai buffet lunch.
