    StandoutExceptional marine biodiversity

    White Rock is a good choice for those starting their diving journey around Koh Tao. It’s a rocky reef, mostly around 17 meters deep, making it easy to manage for beginners or for anyone wanting a relaxed, longer dive. We often spot blue-spotted rays resting in the sand here, and plenty of anemonefish darting amongst their homes. The site can get a bit busy during peak season, but if you time it right, maybe an early morning dive, you’ll find it’s a pleasant spot for a couple of tanks.
