Exploring Boeng Yeak Lom#

The dormant volcanic crater lies a few miles east of Ban Lung, the capital of Ratanakiri, surrounded by dense jungle and waterfalls. The lake is perfectly circular, about half a mile (800 m) across and 165 ft (50 m) deep. It - like nearby Boeng Lum Kut - formed in a volcanic eruption roughly 700,000 years ago.

At the entrance, concession stands sell food, drink, and large containers of local rice wine sipped through wooden straws. A walking trail rings the lake (under an hour on foot) with several piers for swimming and shady picnic spots; heading left first lets you finish at the piers on the right. About half a mile past the concession stands, a cultural center sponsored by the Cambodian Community Based Ecotourism Network offers a look into local minority culture and sells handicrafts.
