    StandoutExceptional marine biodiversity

    Koh Khai Nok is a shallow, sheltered spot, perfect for newer divers in the Similans. We often see schools of fusiliers and various reef fish hovering over the modest coral patches. The maximum depth of 16m means plenty of bottom time, making it a good site for refreshing skills or an easy second dive. It’s a gentle introduction to the area’s marine life.
