English: Bantimurung-Bulusaraung National Park is a national park in South Sulawesi in Indonesia. The park contains the Rammang-Rammang karst area, the second-largest karst area known in the world after the one in South-Eastern China. The park is in Maros Regency, 50 kilometers to the north of Makassar (one hour drive) or just 20 kilometers from Sultan Hasanuddin International Airport (30 minutes drive).[3] Most of the Karst formations are tall and steep at almost a 90-degree angle line along both sides of the road from Maros city to Bantimurung continuing on up to the Pangkajene and Islands Regency (Indonesian: Pangkajene dan Kepulauan, commonly abbreviated as Pangkep).
