Exploring Phnom Khieu Waterfall

The name Phnom Khieu means “Blue Mountain” in the local dialect, a nod to the scale of this multi-tiered waterfall. From the end of the road, reaching the falls means a five-kilometre hike through rainforest, though they can be heard from some distance before they come into view. Travellers come from far and wide to swim in the cool, clear pools, and the surrounding forest is good for hiking, provided you stay on well-worn paths and remain aware of the risk of landmines.

The forest shelters a variety of wildlife, and sharp-eyed visitors may spot cobras and pythons; guides in Pailin offer tours for those keen to venture further off the beaten track. For all its beauty, Phnom Khieu saw bloodshed in the late 1970s, when Khmer Rouge fighters hid here and those who were caught were killed in the jungle, a history few visitors would guess at today.
