The MacDonnell Ranges run 644 km east and west of Alice Springs, red quartzite ridges cut by gorges and permanent waterholes. Tjoritja / West MacDonnell National Park is of great significance to its Arrernte traditional owners, and the Larapinta Trail follows the spine of the western ranges from the Alice Springs Telegraph Station to Mount Sonder.
Camping here means choosing a side of Alice, or heading south into the desert. In the West MacDonnells, Ellery Creek Big Hole has a campground you can reach with a caravan, next to a permanent waterhole, and further west, Ntaria Campground at Hermannsburg has power, showers and a laundry. In the East MacDonnells, about 85 km from Alice Springs, Trephina Gorge Panorama Campground is in Trephina Gorge Nature Park, and south of Alice, Rainbow Valley has two designated camping areas.
Close to Alice Springs, Simpsons Gap is about 20 minutes' drive west, and a sealed 17 km bike path near there suits family rides. In Alice, the Alice Springs Desert Park and the Old Ghan Museum are an easy drive from the west and south camps. At Hermannsburg, the Historic Precinct is heritage listed; the mission dates from 1877, and the town is closely tied to the painter Albert Namatjira. At Stuarts Well, Camels Australia is right next to the roadhouse.
Simpsons Gap, known as Rungutjirpa to the Arrernte people, is described as the home of giant goanna ancestors, and black-footed rock wallabies are sometimes seen by its waterhole at dawn or dusk. Ellery Creek Big Hole is a permanent waterhole in the West MacDonnells, and in Trephina Gorge, look for ghost gums and painted finches. Rainbow Valley's 350-million-year-old sandstone cliffs glow brightest at sunset, and out in the desert, Chambers Pillar rises 50 metres above the plain.
Yes. West MacDonnell campgrounds, including Ellery Creek Big Hole and Redbank Gorge, must be booked and paid for through NT Parks before you go, since you can't pay on site. Bring your own drinking water, and note that pets and generators aren't allowed in the park camps.
