Diving and Snorkeling spot - Koh Tao
Okay, so "Diving and Snorkeling spot" is a placeholder name for what’s effectively a string of shallow reefs around Koh Tao, often visited by day boats. We know, generic name, but bear with us. What we love about these spots, specifically the ones just north of Shark Island or tucked into the bays on the east side, is the sheer ease of the diving. It’s rarely deep, maybe 12-15 metres at most, making it perfect for newer divers or those who just want a long, relaxed bottom time without any deco worries. You’re not here for dramatic drop-offs or big pelagics, though a great barracuda might cruise by. We come for the smaller things, the ones that make you slow right down. Think Goldspeckled Shrimpgobies diligently tending their burrows with a Nocturn Goby perched nearby, or a Blue-spotted Stingray half-buried in the sand. The Longfin Bannerfish schools are always a pretty sight, and we’ve spotted more than a few Dragonfish tucked away in the rocky outcrops. Our favourite time to hit these spots is early morning before the crowds, or late afternoon when the light gets that golden glow, really bringing out the colours in the Green Wrasse and Golden Rabbitfish. Visibility can be a bit variable, especially if there’s been some rain or a lot of boat traffic, but on a good day, it’s a calm, easy dive where you can just potter about, enjoying the gentle sway of the water.
