Why should you go there and how do you do it right?

The Coral Cave (Tham Pakarang in Thai) is a limestone cave on Cheow Lan Lake in Khao Sok National Park. It gets its name from the calcite formations that resemble coral. There is no road to it. You take a longboat from the Ratchaprapha Pier in Ban Ta Khun to the Khlong Long arm of the lake, hike through the forest to a small inner lake, and then cross to the cave on a bamboo raft. According to reports, the hike is about 1.2 km (one way) and includes some steep steps where you need to hold on.

Inside, a guide will lead you by flashlight through chambers filled with stalactites and stalagmites. Bats can also be found there. Wear sturdy shoes, as the path can be muddy and slippery after rain, and bring a waterproof case for your mobile phone. Most visitors see Cheow Lan Lake as part of a day trip or while staying in a floating hut. The lake fee is 300 baht for foreign adults, plus a 40 baht dock fee.
