Kbal Spean is an ancient Khmer site in Phnom Kulen National Park, a remote place located at considerable distance from Siem Reap and the main Angkor monuments. The site stretches out over a length of about 150 meters through the jungle along the Stung Kbal Spean river, known as the “river of a thousand lingas”.

There is no temple at Kbal Spean. The river bed is covered with hundreds of lingas, while depictions of Hindu deities have been carved into the rock along and in the river. Most of the lingas and carvings were made in the 11^th century during the reign of King Udayadityavarman II.

To protect the lingas and sculptings from further decay the river bed has been fenced off; visitors can view the ancient sculptings from a small distance. Kbal Spean which translates to “stone bridge head”, is named after the natural stone bridge under which the river flows for a section.
