Dive Site Overview
This reef dive site, situated on the west side of Koh Koun island, is notably influenced by currents that often funnel in schools of fish, creating dynamic scenes. Divers can anticipate a vibrant hard-coral reef hosting a wide array of marine species.
Below the surface, the site frequently presents fusiliers and juvenile barracuda navigating the currents. These pelagic species often use the reef's structure as a natural current break or feeding ground. Macro enthusiasts will find a rich environment for discovering nudibranchs, pipefish, and various crustaceans, including lobsters tucked into crevices.
Observing the smaller inhabitants here requires a keen eye and patience. There's even a chance to spot unique sawblade shrimps blending with the corals.
Topography primarily consists of gently sloping reef formations, allowing for a relaxed exploration pace despite the potential for moving water. Average depth here is around 14 m, with the maximum depth reaching 16 m (52 ft), ensuring it caters well to recreational dive limits.
Visibility can vary, with reports suggesting 5-10 m on some days; however, during optimal conditions, it can offer clear views of the busy reef ecosystem. Currents typically range from 0-3 knots, influencing the movement of both divers and marine life.
