Tham Lae Khao Kob is located in Huai Yot District, Trang. It is a natural attraction with stalagmites and stalactites along a distance of 4 km. Tham Lae Khao Kob has an underground waterway which requires a boat going along the stream to visit the beautiful stalactites and stalagmites, which are still growing. One of the wonderful things of this cave, considered Unseen Thailand, is that the last cave does not allow walking but lying down on a boat along the cave with a distance of about 800 meters. Although it is only a short distance, such moment is quite exciting for tourists. In some parts, the face and body is very close to the wall of the cave.
