Kbal Spean which means Bridge Head is a river of carved relief stones. The ‘bridge’ is a natural sandstone arch. These stone carvings are mainly of lingams (phallic symbol of the Hindu god Shiva). Also known as the River of 1000 Lingas, the trail head is about 48km to the north of Siem Reap. I was curious about seeing these and thought it would be a change from the temple agenda.
