Tham Nam Thalu

Cave in Khao Sok National Park

Reached on foot from the southwestern shore of Chiaw Lan Lake, Tham Nam Thalu contains striking limestone formations and subterranean streams. It is only partially accessible during the rainy season and we don't recommend visiting then; there have been fatalities. You'll need a guide (1200B) at any time, which can be arranged at the Khao Sok National Park Headquarters.
