Simpsons Gap

Simpsons Gap is one of the West MacDonnell Ranges' most dramatic and accessible gaps, a sheer-walled chasm carved through ancient quartzite by a now-dry creek. Just 18 kilometres west of Alice Springs, this is where the iconic red-rock country of the Red Centre first reveals itself to travellers heading out on the Larapinta Drive. The gap is a vital refuge for wildlife, especially black-footed rock-wallabies, and its permanent waterhole and ghost-gum-lined creek bed offer a classic Outback scene that's at its best in the soft light of morning or late afternoon.

Highlights & What to See

• Simpsons Gap Walk – An easy 1.4 km return walk from the car park into the gap itself, following a sandy creek bed flanked by river red gums and spinifex. The towering walls close in as you approach the waterhole, creating a natural amphitheatre of red, purple and orange bands.
• Rock-wallaby spotting – The permanent waterhole attracts black-footed rock-wallabies, which are most active at dawn and dusk. Scan the cliffs and boulders patiently; their camouflage is remarkable.
• Ghost gums and river red gums – The stark white trunks of ghost gums against the deep red cliffs are an iconic Central Australian photo opportunity, especially in the golden hour.
• Cassia Hill Lookout – A short, steep 800 m return trail that climbs onto the range for panoramic views over the gap and the surrounding spinifex plains. Best done in the cool of the morning.
• Bicycle path from Alice Springs – A sealed 18 km cycleway runs from the Alice Springs Telegraph Station to Simpsons Gap, following the old railway alignment. It's a popular ride for fit cyclists, with interpretive signs along the way.

Suggested Time to Spend

Most visitors spend 45 minutes to 1.5 hours exploring the main walk and lookout. If you're keen on photography, wildlife watching or the longer cycle ride, allow 2–3 hours. Simpsons Gap works perfectly as a short morning or late-afternoon excursion from Alice Springs, or as a first stop on a West MacDonnell Ranges self-drive itinerary. The gap is also a key water stop for Larapinta Trail hikers, though day-trippers won't need more than a half-day here.
