Phraya Nakhon Cave is a vast cavern high on a hill with a royal history is a favourite destination for visitors in the Sam Roi Yot national park. The most popular attraction of the cave is Phra Thinang Khuha Kharuehat, a fourgabbled roofing pavilion construced during the reign of King Rama V in the Year 1890. With its beauty and distinctive identity the pavilion is now used as the symbol of Prachap Khiri Khan province. The cave is actually two large sinkholes, the roofs of which have collapsed allowing sunlight and rain to reach the floor, where trees have rooted reaching for the ceiling. Phraya Nakhon Cave can be reached from Laem Sala Beach, by a steep rocky trail, 430 m long and rising to a height of 130 m, taking about 30 minutes to climb.
You can shorten the way by boat from Laem Sala Beach.
