The Gua Leang Leang caves are noted for their ancient paintings. The age of these is unknown, but relics from nearby caves have provided glimpses of life from 8000 to 30,000 years ago. There are 60 or so known caves in the Maros district; the limestone karsts here have more holes than a Swiss cheese.
Catch a pete-pete from Maros to the Taman Purbakala Leang-Leang turn-off on the road to Bantimurung, and walk the last couple of kilometres.
Alternatively, charter a pete-pete from Maros and combine it with a trip to Air Terjun Bantimurung waterfall.
