Nestled deep within Thailand’s Khao Sam Roi Yot National Park, almost 300 kilometres south of Bangkok, the Phraya Nakon Cave is one of the most exquisite caves in Thailand and definitely one of the most photographed. The main attraction is the Kuha Karuhas pavilion located inside the Phraya Nakhon. The pavillion was built by King Chulalongkorn (Rama V) in the 1890, when he visited the place and fell in love with its beauty. Later, King Prajadhipok (Rama VII) and the present King of Thailand, King Bhumibol Adulyadej (Rama IX) also visited the cave. The main chamber contains the signatures of both King Rama V and King Rama VII on the wall.
