Tham Khao Wang Thong is a limestone cave system in Kuan Thong Subdistrict, Khanom District, Nakhon Si Thammarat Province, southern Thailand. Located inland from Khanom town, it is known for its large chambers with stalactites, stalagmites, columns and flowstone formations. Accessed by a short hillside climb and guided walk, the cave is a popular natural attraction in Khanom valued for its geology and accessible eco-tourism experience near the coast.

Visitors can expect a guided walk through a limestone cave with multiple chambers featuring stalactites, stalagmites and drapery formations. Access involves a short stair climb to the cave entrance and walking on uneven, sometimes slippery surfaces inside with artificial lighting in parts. Local guides lead visitors through narrow passages and larger halls, explaining formations. The surrounding area is forested hillside with parking and basic facilities at the base.
