A number of scenic gaps pierce the West MacDonnell Ranges. One of these is Simpsons Gap, site of one of the most prominent waterholes in the region. The area is an important spiritual site to the Arrarnta Aboriginal people, where several dreaming trails and stories cross. At dawn or dusk Simpsons gap it is renowned as a place to see black-footed rock wallabies along the site's short walking track. Good examples of many of the vegetation communities of the MacDonnell Ranges are found in the Simpsons Gap area, including large stands of mulga, and the area around the gap is a major stronghold for over 40 rare and relict plants.
