Gomantong Caves

Close to the Danum Valley, the Gomantong Caves are surrounded by primary rainforest (orang-utans are common here) and home to millions of bats and cave swiflets. The caves have a remarkable guano-based ecology and, at certain times of the year, local villagers can be observed precariously traversing the high cave walls on bamboo ladders as they harvest disused nests for making bird’s nest soup.
