Sam Roi Yot national park

The Khao Sam Roi Yot national park is located in southern Thailand, 60km south of Hua Hin along the coast of the gulf of Thailand. It covers an area of 98 km² of which 21 km² are marine areas. The national park was established in 1966.
The main access point is in Bang Pu. From the beach it's possible to take a boat for the short trip to the park HQ or walk on a short trail along the coast. Visitor arrive in the sandy Laem Sala beach. From here a steeper trail leads to the Phraya Nakhon cave, a large cave system where one of the caves has an opening on the top allowing the sunlight to come in. At the bottom of the open cave trees are growing and a small temple (Khuha Kharuehat) has been built. The cave has no artificial lighting.
