The story of Sung Sot Cave

Sung Sot means 'Surprise Cave', the reaction of French explorers who found it in 1901. Inside, the first chamber leads to a second, even larger hall the size of a stadium.

Rainwater has shaped the limestone for millions of years into columns and figures that guides compare to animals and warriors. A viewpoint at the exit looks over a lagoon full of boats.
