Phnom Khieu Waterfall

Phnom Khieu Waterfall at a Glance#

Address: Phnom Khieu area, Cambodia

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.

Best Time to Visit Phnom Khieu Waterfall#

For best waterfall flow and reasonable access, visit late in or just after the rainy season (roughly August-November).

After the rainy season (Best for waterfalls)

August-November · 24-32 °C

Higher water flow makes the waterfall most impressive; trails may still be muddy soon after heavy rains.

Dry cool season

November-February · 22-30 °C

Drier, more comfortable temperatures for hiking and visiting, and generally easier access to the site.

Wet season

May-October · 24-32 °C

Frequent heavy rains swell streams and falls but can make trails slippery and access difficult during peak storms.
