Battambang

Battambang Province is in northwestern Cambodia and borders onto Thailand. The best known caves are the "Killing Caves" at Phnom Sampeu, one of the most visited tourist sites in the area. However there are many more limestone hills in the area, although many of the caves are used as temples. The limestone extends from west of Battambang town and continues west towards Pailin on the Thailand border. The landscape from Battambang to at least Sdao is totally flat with the karst hills rising up to 300m from the plain.

During the June 2008 expedition, in 14 days of caving, 65 caves were registered, and 54 of those were visited and 45 of them mapped. A total of 4,253 m of passage was surveyed (by 3 people).
