After 14 years in development, the Adelaide100 trail is emerging as one of Australia's most ambitious urban hiking routes. Spanning over 100km, this loop offers a unique way to experience Adelaide, connecting the city centre, suburbs, coastline, and the scenic Adelaide Hills.
Much of the trail is already open, giving adventurers the chance to explore some of the region’s top highlights — including Mount Lofty, Adelaide Zoo, and renowned Adelaide Hills wineries.
The idea was spearheaded by Jim McLean from Walking SA, a not-for-profit dedicated to encouraging outdoor activity. Inspired by the historic “Hundred of Adelaide” — a 19th-century land division roughly 100 square miles in size — McLean envisioned a route that loosely follows this original boundary. By linking existing walking tracks, the Adelaide100 forms a continuous path around the city.
One of the trail’s biggest strengths is its accessibility. Hikers can start from virtually anywhere and tackle the journey in sections. The full circuit takes about five to six days to complete, but it’s officially divided into seven manageable segments. So far, five sections are open:
Monument Road, Norton Summit to Newton (21km)
The most rugged section, passing through Morialta Conservation Park with stunning waterfalls and lookouts.
Newton to Adelaide City (16.7km)
A tranquil walk along the River Torrens/Karrawirra Parri into the heart of the CBD.
Adelaide City to West Beach (14.2km)
A coastal journey leading from the city to the beach.
West Beach to Kingston Park (11km)
A seaside walk before the trail veers inland.
Kingston Park to Majors Road (6.8km)
A gentle path through green reserves and parklands.
With various accommodation options, from boutique city hotels to vineyard stays in the hills, the Adelaide100 offers something for every kind of walker — from casual strollers to dedicated hikers. It’s a fresh, immersive way to discover the diverse landscapes and culture of Adelaide.
