Nam Talu Cave
ถ้ำน้ำทะลุ
A limestone cave with an underground river running through the mountain. Visitors wade and swim through with headlamps, making it Khao Sok’s most thrilling adventure route.
Nam Talu Cave is located in the rainforest on the lake’s northern shore. From the floating bungalows, it takes a boat ride followed by a hike of about 1.5 hours through the jungle to reach it. Then, led by a guide, visitors travel about 1 hour through the cave along an underground river. Some sections require swimming, with water reaching chest height. Bats, cave spiders, and stalactites can be seen along the way. A licensed guide is required, and the cave is closed during the rainy season or after heavy rain (a flash flood accident occurred here in 2007). The trip requires a reasonable level of fitness. Wear non-slip water shoes and bring a waterproof bag.
