The famous bat exodus in Mulu National Park, Sarawak.
Approximately 3 million bats live in Deer Cave and leave near dusk by
the thousands in long snake-like formations to feed on insects...
Water seeps through the limestone roof of Deer Cave and falls 122m to the cave floor. Back-lit by the main entrance, where the famous bat exodus occurs nightly, the waterfalls give a surreal feel to an already otherworldly place.
