Tnorala (Gosse Bluff)

Rising from the red desert west of Alice Springs, Tnorala (Gosse Bluff) is a colossal circular crater formed by a comet impact some 142 million years ago. To the Western Arrernte people, this dramatic ring of sandstone is a sacred site where a celestial baby fell to earth, creating the Milky Way. Today, it’s a remote and mesmerising natural wonder that feels like landing on another planet.

Highlights & What to See

• Walk the crater rim: The 4.5 km Tnorala Walk (Grade 3) takes you up onto the raised rim for jaw-dropping views across the 5 km-wide crater floor and the surrounding West MacDonnell Ranges. It’s the best way to appreciate the sheer scale of the impact.
• Look for the central bulge: Unlike many craters, Tnorala’s centre is raised – a ‘central uplift’ created by the rebound of rock after impact. From the rim you can pick out this distinctive dome.
• Photograph the geological layers: The steep walls reveal tilted layers of sandstone and quartzite, twisted almost vertical by the force of the collision. Early morning or late afternoon light makes the colours pop.
• Learn the Dreamtime story: Pick up a brochure from the visitor shelter at the start of the walk – it explains the Western Arrernte interpretation of the crater’s formation and its deep cultural significance.
• Spot desert wildlife: Keep an eye out for red kangaroos, dingoes and perentie lizards that inhabit this arid landscape, especially around dawn and dusk.

Suggested Time to Spend

Allocate at least half a day for Tnorala. The drive from Alice Springs takes about 2.5 hours (160 km) on the sealed Namatjira Drive, then 10 km on a rough gravel road (4WD recommended after rain). The walk itself takes 1.5–2 hours, plus time to soak in the views and picnic. Most visitors combine it with a full-day exploration of the West MacDonnell Ranges, leaving Alice Springs early and returning by late afternoon.

Nearby Areas Worth Combining

• West MacDonnell National Park: A string of gorges and waterholes including Simpsons Gap, Standley Chasm and Ormiston Gorge – all on the way to Tnorala.
• Ormiston Gorge & Pound: A spectacular waterhole and walking trail about 50 km before the turn-off to Tnorala; perfect for a swim or a 7.5 km loop walk.
• Glen Helen Gorge: A permanent waterhole at the base of the ranges, with a historic homestead and basic accommodation 20 km before the crater turn-off.
• Finke River: One of the world’s oldest river systems, visible from several points along Namatjira Drive; it meanders through ancient landscapes.
• Hermannsburg Historic Precinct: A former Lutheran mission settlement with well-preserved buildings and an art centre showcasing Western Arrernte artists – about 50 km south of the turn-off.
