Belilena, a cave complex near Kitulgala, is one of the important finding places of the prehistoric Balangoda culture in Sabaragamuwa Province. E.P. Deraniyagala, Sri Lanka’s most renowned anthropologist, found remnants from Sri Lanka’s stone age in Belilena during his excavations from 1978 till 1983. He discovered skeletal remains of ten human beings who lived more than 30.000 years ago. Belilena is declared an Archaeological Reserve. But not much is left from the Balangoda culture in situ. Nonetheless, Belilena is a rewarding destination due to ist natural beauty. It’s an entire group of caves, one of them behind a veil of a small waterfall.
