The bat species typically observed here is the wrinkle-lipped free-tailed bat (Chaerephon plicatus).
Colonies of wrinkle-lipped bats can consume several tons of insects, such as rice pests, in a single night.
The emergence is a synchronized natural defense mechanism used by the bats to overwhelm potential aerial predators like hawks.
The limestone caves in the Noen Maprang district are part of an ancient geological formation that predates much of the surrounding basin.
Bat Sighting Point in Ban Mung, Noen Maprang, is a natural wildlife viewing area where millions of wrinkle-lipped bats emerge from limestone karst caves at dusk. The phenomenon occurs in a steady stream that can last for nearly an hour, creating a long, dark ribbon visible against the evening sky. The location is situated at the base of dramatic, craggy limestone mountains characteristic of the Phitsanulok landscape. Visitors typically gather at designated ground-level spots to watch the bats head out toward agricultural fields to feed on insects. The surrounding area features karst topography, providing a stark backdrop to the ecological display.

Bring insect repellent, as the bats' arrival coincides with the active period for mosquitoes.
Position yourself with a clear view of the mountain silhouette against the fading sunset to see the bats clearly.
Avoid using flash photography, as it can disrupt the flight paths of the emerging colony.
Do not attempt to climb or enter the caves, as they are essential habitats for the bats and may be structurally unstable.
Maintain silence to avoid disturbing the local wildlife and surrounding community.
