Namtok Lan Rak or Namtok Tat Hin Kong 

Situated in Phramani Sub-district on the way to Namtok Sarika and Namtok Nang Rong, this is a unique waterfall originating from a small stream which flows through a large rocky formation at the foot of a small hill. The best time to visit the waterfall is during the rainy season. To get there, take a left turn at Prachakasem intersection (about 8 kilometers on the route to the Saithong Reservoir), and then proceed for another 5 kilometers.
