Simpsons Gap
Rungutjirpa
Ancient gorge, permanent waterhole
On the lands of the Arrernte people.
schedule 2 min read / Updated Jun 2026
Simpsons Gap, known as Rungutjirpa to the Arrernte people, is one of the most striking natural landmarks in the West MacDonnell Ranges, cutting through ancient quartzite about 18 kilometres west of Alice Springs. Sheer red and orange cliffs plunge to a permanent waterhole fringed with ghost gums, where black-footed rock-wallabies shelter in the crevices and emerge at dawn and dusk. The gap marks the eastern end of Section 1 of the celebrated Larapinta Trail.
Rungutjirpa sits within Tjoritja, the West MacDonnell National Park, a protected reserve that stretches more than 160 kilometres west of Alice Springs. The MacDonnell Ranges themselves were pushed upward during the Alice Springs Orogeny some 300 to 350 million years ago, compressing sediment that had been laid down in shallow seas roughly 800 million years earlier. The result is some of the most ancient and visually arresting rock scenery in Australia, and Simpsons Gap is among its finest expressions.
For the Arrernte Aboriginal people, Rungutjirpa has been a place of deep spiritual importance for countless generations. It is understood to be the mythological home of a group of giant goanna ancestors, and several dreaming trails converge at this waterhole. Multiple songlines cross the site, encoding knowledge of the landscape, its water sources, and seasonal patterns. Visitors are asked to treat the site with respect as a living cultural landscape.
The permanent waterhole at the base of the gap is an ecological anchor in this arid country, supporting a range of rare and relict plant species including stands of mulga and ancient ghost gums whose white trunks glow against the red quartzite. The black-footed rock-wallaby, a vulnerable marsupial, shelters in narrow cliff crevices through the heat of the day. At dawn and dusk these small, agile animals emerge to forage along the rocky ledges, offering photographers and wildlife watchers an extraordinary spectacle.
Three short walking tracks suit different fitness levels: the Ghost Gum Walk is a gentle loop taking in the waterhole and its signature trees; the Cassia Hill walk provides a broader view over the ranges; and the Woodland Trail winds through mulga scrub. For more serious walkers, Simpsons Gap is the terminus of Section 1 of the Larapinta Trail, the 231-kilometre long-distance track that traverses the West MacDonnell Ranges all the way to Mount Sonder. A sealed, 17-kilometre cycling path also links Simpsons Gap to Flynns Grave on the edge of Alice Springs, making it popular with cyclists.
Entry to Tjoritja requires an NT Parks Visitor Pass, available online before arrival. A gas barbecue and picnic facilities are provided in the shade near the car park, and public toilets are available. Water is provided but must be boiled before drinking. The site opens at 5am and closes at 8pm daily, with Larapinta Trail walkers permitted to camp overnight by advance booking. Swimming in the waterhole is not permitted, preserving its ecology and cultural integrity.
