Why dive here
With 54+ marine species recorded in the area - including sea turtles, tiger sharks and pufferfish - Boyancy offers some of Koh Tao's richest diving. Water ranges 29-31°C, warmest April, May, June.
Boyancy, for us, is one of those Koh Tao sites that often gets overlooked, which is exactly why we love it. You drop down onto a sandy bottom, usually around 10-12 metres, and then it’s about slow exploration. We’ve had some fantastic luck here spotting the smaller stuff – those Nocturn Gobies are a treat, and the Filamentous Blennies pop up from every crevice. Keep an eye on the staghorn coral patches; they’re often nurseries for juvenile Blue Trim Parrotfish. The real draw, though, is the chance of a Blacktip reef shark cruising by in the blue, especially in the early mornings before the boats really pick up. We’d suggest going then, or late afternoon, to avoid the day trippers. It’s a great spot for photographers keen on macro subjects, or anyone who enjoys a relaxed dive without feeling rushed. The currents are usually mild, making it a comfortable drift. You’ll spend most of your time scrutinising the reef for Eye-spot Butterflyfish and those busy Cleaner Wrasse stations.
