Phnom Sampeau Bat Cave

The Phnom Sampeau Bat Cave is one of Cambodia's most astonishing natural wildlife spectacles, occurring every evening at dusk when an estimated three million wrinkle-lipped free-tailed bats emerge from fissures in the limestone cliffs of Phnom Sampeau hill outside Battambang city. The exodus begins around 30 minutes before sunset and continues for over an hour, with the bats pouring out in a continuous undulating ribbon that spirals thousands of meters into the sky in swirling columns visible for kilometers around. Resident bat hawks and other raptors dive repeatedly through the stream to pick off individual bats in dramatic aerial hunts. Visitors gather on the hillside road and in the fields below with binoculars and cameras. The sheer scale and duration of the emergence makes it a genuinely unforgettable experience.
