Once a day up to 2 million wrinkled lip bats exit their cave outside Khao Yai National Park to feed. I was hoping to find a decent location to photograph the swarm from a distance, however I met a girl and her sister who became my guides on a hike and climb to the very mouth of the cave. The video isn't professional but it conveys my amazement at this once in a lifetime opportunity.
