Katherine Gorge, a deep gorge carved through ancient sandstone by the Katherine River, is the central attraction of the park. Katherine Gorge is made up of thirteen gorges, with rapids and falls, and follow the Katherine River, which begins in Kakadu. During the Dry, roughly from April to October, the Katherine Gorge waters are placid in most spots and ideal for swimming and canoeing. There may be freshwater crocodiles in most parts of the river, as they nest along the banks, but they are harmless to humans. Saltwater crocodiles regularly enter the river during the wet season, when the water levels are very high, and are subsequently removed and returned to the lower levels at the onset of the dry season. Thus, swimming in the wet season is prohibited. Cruises of various lengths go as far as the fifth gorge.
