Sail Rock isn’t just another dive site — it’s the best dive site in the entire Gulf of Thailand. While Koh Tao is famous for diving, don’t be misled — Sail Rock easily outshines Koh Tao’s dive spots in beauty and biodiversity.

Ask any experienced dive pro from Koh Tao, Koh Phangan, or Koh Samui which site is the most spectacular in Thailand — the answer is always Sail Rock.

📍 It’s the closest major dive site to Koh Phangan and Koh Samui, and while it’s the furthest from Koh Tao, many schools from all three islands run regular dive trips there — because it’s absolutely worth the journey.

🏝️ Sail Rock is a massive, freestanding pinnacle rising from 40 meters deep to 10 meters above sea level in the middle of the open ocean — a magnet for marine life of all kinds.

Inside the rock, you’ll discover a vertical chimney swim-through from 18m to 6m — a true underwater adventure. Just east of Sail Rock lies Secret Pinnacle, a submerged reef starting at 15m, teeming with even more marine life.
