This Park is known for unique features such as a small pond in a rock crevice called “Tham Pla”(Fish Cave) width 2meters, depth 1.5 meters, which is teeming with a carp species of fish.

The stream which feeds the pond also runs underneath a hill. The whole area is surrounded by a mixed deciduous forest and is drained by the mae sawi river.
