You step out of an air‑conditioned van onto a patch of red earth and immediate humidity—the mountain draws you in with the scent of wet limestone and palm sugar smoke. Ahead, the track drops toward the waterfall; to one side, a river bed hosts neat rows of carved lingas that have kept their silence for more than a millennium. The day on Phnom Kulen moves in chapters: a slow village stop where palm cake is made over open flame, a climb to the reclining Buddha cut from sandstone, a walk beside the carved river, and finally the broad, tumbling Kulen falls where swimmers and local families share shallow pools.
