Ranked as one of the planet's top 20 treks, the Larapinta Trail is a 223 kilometre path that follows the rocky spine of the West MacDonnell Ranges from Alice Springs Telegraph Station to Mount Sonder. Challenge yourself to hike the whole trail or tackle one of its 12 sections, all of which vary in difficulty and length. Each section can be reached by four-wheel drive, so you can join or leave the trail at any of the Tailheads. The Trail encompasses some of the key attractions of the ranges including Simpsons Gap, and the permanent waterholes at Ellery Creek Big Hole, Ormiston Gorge and Glen Helen. It weaves past some of the world's most ancient metamorphic and igneous rock and nearly 600 species of rare flora. The Trail also links in with other walking tracks within the West MacDonnell National Park, allowing side trips to explore more of the Park. Along the way you camp under the stars. Most camp sites have picnic tables and tent sites. All Trailheads have a water supply and some have free gas barbecues. Fully guided tours are available, otherwise set off on your own ensuring you're well equipped and have notified the relevant authorities.
