Located 23 km from Alice Springs in the West MacDonnell National Park, the site incorporates a number of scenic gaps, including Simpsons Gap, one of the most prominent gaps in the West MacDonnell Ranges. It is renowned as a place with excellent opportunities to see Black-footed Rock-wallabies along short walks into the Gap at dawn or dusk.
Other smaller gaps including Bond Gap, Spring Gap, Rocky Gap and Wallaby Gap are accessible via the Larapinta Trail or Woodland Trail.
Large representative samples of many of vegetation communities of the MacDonnell Ranges are incorporated into Simpsons Gap area including large areas of Mulga. It is a major stronghold for over 40 rare and relict Northern Territory plants.
The area is an important spiritual site to the Arrernte Aboriginal people where several dreaming trails and stories cross.
