Ultimate 3S / 4S and double Sail Rock
🌊 Sail Rock — Every Day. No Exceptions.
Here’s what makes The Divers Boat truly different: we go to Sail Rock every single day.
Sail Rock is widely considered the best dive site in the entire Gulf of Thailand. A submerged pinnacle rising from 40 metres to just 10 metres below the surface, it’s home to whale sharks, massive schools of barracuda, giant groupers, fusiliers and some of the most spectacular underwater landscapes in Southeast Asia.
Most dive centers in Koh Tao visit Sail Rock occasionally. We go every day — and on our signature excursions, we combine it with the most exclusive sites on the island.
🏆 Our Signature Excursions — Only at The Divers Boat
These full-day trips are our trademark. No other dive center in Koh Tao offers these combinations as regular daily departures.
