Shallow reef and coral-nursery boat site south of Thongsala.
Ko Tae Nai is normally run as a short local boat dive or snorkel stop from the Thongsala area.
Ko Tae Nai is a shallow west-side reef and snorkel-friendly boat site just south of Thongsala, with coral patches, nursery structures, and easy terrain over sand and rubble. It usually feels gentle enough for newer divers, though light current and day-to-day conditions still shape how relaxed the site feels.
Safety Notes
Ko Tae Nai is usually straightforward, but treat any building current or choppy surface conditions as the main planning variable.
