Phnom Kulen is both a geological plateau and a historic ceremonial site where early Khmer rulers performed royal rites; riverbed carvings date to Angkor-period temple artisans.
Conservation

Timing matters

Carry 1–2 L of water and pace climbs during midday; there are limited vendors inside the park.
