A small hill, Khao Tham Taphap is located in Tambon Wang Hin of Ban Rai district 56 kilometres from town on Highway No. 333. There is a right turn leading to the cave, a further distance of three kilometres. The entire cave complex is made up of several caverns. All beautifully adorned by stalagmites and stalactites. In the tunnel behind the cave is a snapping turtle-like rock formation, hence the name Tham Taphap. Pre-historic tools have also been found around the site.
