The park is in the areas of two provinces: Satun and Trang. It consists of a long coastline from Amphoe Langu to Amphoe Thung Wa and several offshore islands such as Ko Phetra, Ko Khao Yai, Ko Lalobaentae, Ko Lidi, Ko Bulon,Ko Laoliang, and Ko Perama.Boats to these islands are available from the Pak Bara Pier. Ko Kao Yai, the largest in the group, boasts several pristine beaches suitable for snorkeling, swimming, sunbathing, camping, and seeing the famed Rock Castle.
 

Between Ko Kao Yai and Ko Lidi is a channel bay known as Ao Kam Pu. Ao Kam Pu is a tranquil passage with cascading waters during certain tidal changes and some coral at shallow depths. Another tourist attraction is Ko Bulon Leh, approximately 22 kilometres west of Pak Bara. Bulon Leh has a fine white-sand beach runs along the east and the north shores of the island and has some fine coral sites that make for good snorkeling.
