Rainbow Valley Conservation Reserve is a protected area located south of Alice Springs, Northern Territory in Australia.
[6] Rainbow Valley's main sandstone formation is known as Wurre by the local Aboriginals, the Twertentyeye group of Upper Southern Arrernte people,[3]: 16 and is a significant part of their homeland which they call Imarnte.
The unsealed dirt access road heads east then southeast for 22 km (14 mi) to a parking lot situated on the west side of a claypan that extends northwest from the base of the main sandstone formation.
"[6] The joint management plan's official document, however, refers to the access road as "suitable for conventional vehicles driven with care" but still recommends 4WD for the final 1.4 km (0.87 mi) around the claypan.
The dark red caprock contains the most iron and is more resistant to erosion than the lighter coloured sandstone layers, which delays the eventual collapse and disintegration of the formations.
[5] More than 400 plant species are found in Rainbow Valley including spinifex grasslands, acacia shrubs and coolibah trees in the western part of the reserve.
The grey falcon, redthroat and red-tailed black cockatoo are listed as lower risk near threatened under the Territory Parks and Wildlife Conservation Act (TPWCA).
[3]: 13, 40 To the south of the main sandstone formation, a massif called Ewerre by the Twertentyeye is registered as a sacred site, as well as all the surrounding area within 50 m (160 ft) of that rock.
The black rocks lying on the northern side of the main formation are also considered significant natural objects that are not to be moved from their current locations.
