Wat Tham Khao Luang

Khao Luang Cave has stalactites and stalagmites across its walls and wide openings where sunlight falls on the rock. King Mongkut (Rama IV) once visited the cave and had a stairway built from the foot of the hill down to the cave floor.

The cave holds old Buddha images placed here before the Rattanakosin era, such as a 14 m reclining Buddha, which Rama IV had restored. He also had four 'reign' Buddha images made, dedicated to Kings Rama I–III and to himself.

Under King Chulalongkorn (Rama V) a temple was established in the cave to make merit for his father, and more images were added, including five reign images. A large troop of monkeys lives here.
