About the National Park

This national park is unique in that it is the first marine national park in Thailand.

The diverse terrain is bordered by unspoiled beaches, small bays, with the range of limestone mountains in the background, from where the area was named

In between is the winding canal, that passes through traversing mangroves and natural marshlands.

The most recognised attraction in the area is the Phraya Nakhon Cave. The cave is actually a huge cavern, housing a beautiful pavilion that has traditionally been visited by Thailand's rulers.
