In the midst of the jungle, cool water rushes over a skilfully carved river bed, known as Kbal Spean or the 'River of a Thousand Lingas'. The phallic symbols of fertility have been shaped into the rocks along with some deities that recline under a set of rapids. It takes about 1½ hours to get here from Banteay Srei on a sandy track. From the entrance, it is another 30-minute walk. The trip out here is best combined with a visit to Banteay Srei.
