Than Bok Khorani National Park is a protected area in Krabi province, southern Thailand, that conserves lowland rainforest, limestone karst and freshwater systems. The park is noted for its karst hills, forested valleys and accessible natural pools.

  • Best time to visit: Best visited during the dry season when tracks and pools are most accessible and water is clearer for swimming.
