Wycliffe Well, located 130 kilometres south of Tennant Creek and 380 kilometres north of Alice Springs, has built a reputation around extraterrestrial sightings in the area. Wycliffe Well began as a market garden to supply the troops going to and from Darwin during World War Two. As the highway developed further after the war it became a roadhouse supplying fuel and provisions to travellers and eventually as tourism increased has transformed into a substantial and well equipped holiday park. Located nearby is the Devils Marbles Conservation Reserve and the gateway to the Davenport Range (proposed) National Park
