Phnom Kulen
📍 Siem Reap Province, Cambodia
A forested sandstone plateau northeast of Angkor where a wide waterfall pours into jungle pools, and the riverbed upstream is carved with a thousand ancient sculptures beneath the flowing water.
What makes it marvelous
Phnom Kulen is a forested sandstone plateau that rises from the Cambodian plain, the plateau on which the founding of the Khmer Empire was proclaimed in the early 9th century. A river runs across the plateau and drops in a broad, powerful waterfall into pools below; upstream, the sandstone riverbed is carved in relief with hundreds of lingas and figures — the 'River of a Thousand Lingas' — so that the water runs directly across stonework close to a thousand years old. A giant reclining Buddha, cut from a single boulder, crowns the hill.
Why visit
The wide waterfall crashing into jungle pools is a refreshing contrast to the temples of nearby Angkor, and you can swim in the shallows below it. Wading the carved riverbed, watching clear water run over ancient sculptures, is quietly extraordinary, and the plateau's forest, carvings, and reclining Buddha pack a great deal of history into one hilltop.
What to know before you go
🗓️ Best time
The dry season (roughly November to April) makes the plateau's rough roads easiest; the waterfall is fullest in and just after the rains, so the shoulder months balance flow and access.
🧭 Getting there & access
About 1.5–2 hours by road northeast of Siem Reap, on a rough mountain track that usually needs a sturdy vehicle or a tour. A ticketed site; the access road up the plateau is often one-way by time of day.
Good to know
- Go with a driver or tour — the plateau road is rough and timed one-way in places.
- Bring swimwear for the waterfall pools, and modest dress for the shrines.
- Start early to combine the falls, the carved river, and the reclining Buddha.

👁️ What to expect

- The view
- The wide waterfall into its jungle pool, or clear water running over the carved lingas. Post-rain flow is strongest; the dry season eases access.

Phnom Kulen is where the Khmer Empire was born, and it remains one of the country’s most striking upland landscapes. This forested sandstone plateau, rising above the plain northeast of Angkor, was where a king proclaimed the empire’s founding in the early 9th century. A river crosses the plateau and tumbles over a broad, powerful waterfall into pools where visitors cool off in the jungle heat — but its deeper marvel lies just upstream, where the sandstone riverbed is carved in relief with hundreds of lingas and figures, so that the water itself runs across stonework close to a thousand years old.
Above the falls, a colossal reclining Buddha carved from a single boulder draws pilgrims to the hilltop. A visit strings together a swim beneath the waterfall, a wade up a river running over ancient carving, and a walk through forest that is a genuine relief after the heat of the plain. Reached by a rough plateau road from Siem Reap, it is a green counterpoint to the stone temples that made Cambodia famous.
