It features sandy bottoms near the edges and vibrant coral reefs towards its center, notably around a prominent pinnacle. There is no specific historical information provided for this site, but its layout makes for straightforward navigation, focusing around the central coral structures.
The site is teeming with typical reef fish found in Koh Tao. Divers and snorkelers can expect to encounter colorful butterflyfish, active parrotfish, the ever-popular clownfish nestled in their anemones, and various species of wrasses, all contributing to a lively underwater ecosystem.
