StandoutExceptional marine biodiversity

Koh Bon, The Bay gives you a pleasant, easy reef dive, especially if the main ridge is a bit too much current for comfort. It’s a good spot to just settle in and watch the smaller stuff, sometimes you’ll see leopard sharks resting in the sand at 22m, and the schooling fusiliers here can be pretty dense. We’ve had some very relaxing dives here, just drifting along the coral. It’s perfect for beginners or anyone who fancies a slower pace, leaving the adrenaline for another day.
