Tham Kaeo is situated some 23 kilometres from Pran Buri or 15 kilometres north of the park office. This cave is full of stalactites and stalagmites. Oil lamps can be rented at a nearby village for exploring the cave.

Tham Sai, is 9 kilometres north of the park office. Exploration inside the cave takes about half an hour. Oil lamps can be rented at nearby Khung Tanot Village.

Hat Laem Sala is located 16 kilometres north of the park office. It can be reached by boat or walking across a hill from Bang Pu Village. Walking up a beachside mountain for a while, visitors will arrive at a famous cave called "Tham Phraya Nakhon". The cave has a big hole through which a shaft of light reaches and permits the growth of various kinds of plants. Phra Thi Nang Khuha Kharuhat, a Thai style pavilion, lends the most attractive sight to the cave and has become the symbol of Prachuap Khiri Khan. It is a four-porched building first constructed in Bangkok in 1890 during the reign of King Rama V, then dismantled and moved to the cave where it was reconstructed. Its gable tops were raised by the King himself.

In addition, there is a viewpoint on Khao Daeng, 400 metres from the park office and Ban Khao Daeng, a canalside village, which is the starting point for a 1 hour boat trip to watch wild birds.
