30-45 minutesSeparate fee
Walk along a wooden boardwalk through the mangroves to reach this sprawling limestone cave network. Hundreds of Malaysian fruit bats live inside. Pay the small separate entrance fee at the door and rent a flashlight.
5 minutesPhoto stop
Look for a prominent karst mountain with a silhouette resembling a giant gorilla. Your boat will pass by this formation in open water. Keep your camera ready because the perspective shifts quickly.
