When divers in a pub or a beach bar start talking about the best spots in the Gulf of Thailand, one name usually tops the list: Sail Rock. It’s that massive granite pinnacle sitting halfway between Koh Tao and Koh Phangan, famous for its “Chimney” and the sheer wall of fish that circles it.
While any trip out there is a win, there are a few ways to make a sail rock dive trip feel less like a standard excursion and more like the highlight of your year. If you’re planning to dive in Sail Rock, Thailand, here’s how to ensure it’s a day you’ll still be talking about years from now.
1. Get Your Buoyancy Sorted for the “Chimney”
The Chimney is a vertical swim-through that’s basically a rite of passage for Sail Rock Koh Tao diving. You enter around 18 metres and go up inside the rock, coming out at either 12 or 6 metres. It’s a brilliant experience, but it can be a bit tight.
- The Secret: Work on your hover. If you can stay still without using your hands, you’ll be able to look at the tiny cleaner shrimp and crabs living in the cracks without bumping into the walls.
- Lighting: A small torch helps. Even on a sunny day, the inside of the rock has shadows that hide some of the coolest macro life.
2. Head to the “Secret Pinnacle”
Most groups stick to the main rock because there is so much to see. However, if you have the air and the experience, ask your guide about the outer pinnacle.
- The Draw: Because it’s a bit further out in the blue, this is where the big stuff hangs out. We’re talking Giant Barracuda and Queenfish that stay away from the bubbles of the main crowd.
- The Catch: You’ll want to be comfortable with a bit of a blue-water swim and potentially a little more current.
3. Go Pro with Your Photos
Sail Rock is famously photogenic. Between the “fish tornadoes” and the sunlight hitting the Chimney exit, you’ll want to capture it.
- Think Wide: Don’t worry about the small stuff. Use a wide-angle lens or a GoPro to get the scale of the schools of fish.
- Stay Shallow: Some of the best light is in the last 10 metres of the dive. Save some battery for the safety stop, as Whale Sharks often cruise by right near the surface.
Frequently Asked Questions
Is a Sail Rock dive site trip okay for new divers?
It can be, but it’s much better if you’re an Advanced diver. A lot of the action happens at 20-30 metres. If you’re still an Open Water diver, you might find yourself looking down at the best parts from above.
How do I actually get there?
Most schools on Koh Tao run a full-day trip. It takes about 90 minutes to 2 hours on the boat. It’s a long day, but usually includes breakfast and lunch on deck, which is a great way to meet other divers.
What should I look out for besides Whale Sharks?
Keep an eye out for the “wall of silver.” This is a massive school of Chevron Barracuda that hangs out off the East side. If you stay still, they often circle right around you.
Ready for the Big Blue?
There’s something about being miles away from land, surrounded by thousands of fish, that reminds you why you started diving in the first place. Whether you’re hunting for a Whale Shark or just want to master the Chimney, Sail Rock never fails to deliver.
