Katherine Gorge is a deep gorge carved through ancient sandstone by the Katherine River. It is made up of 13 gorges, with rapids and falls and follows the Katherine River, which begins in Kakadu. During the dry season 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 but they are considered harmless to humans. Saltwater crocodiles regularly enter the river during the wet season when the water levels are very high. They are subsequently removed and returned to the lower levels at the onset of the dry season. Swimming in the wet season is prohibited. Cruises of various lengths go as far as the fifth gorge and there are walking tracks and scenic flight available.
Katherine Gorge and many of its activities are readily accessible. Barrawei Lookout is a short walk to the top of the escarpment for views of the first gorge and surronding area. From here you can head back or continue on to a slightly longer walk.
