The Adelaide100 walking trail has been a long time in the making. This 100km long-distance loop around Adelaide’s stunning coast, waterways, and hills has been in the works for well over a decade, and now five of the seven sections are open and ready to be explored!
From the mind of Walking SA board member Jim McLean, this epic trail is the perfect way to see the state on foot while exploring the stunning natural beauty.
“Jim McLean got this all together as an idea about fourteen years ago,” shared Walking SA Executive Director Rod Quintrell.
“He thought it would be a great idea to go around a lap of the city. He’s based it on the old Adelaide 100 map and has been working on it ever since.”
Following the founding of Adelaide, in the mid-1800s a unique system for categorising land parcels was established. This was based on land sizes of approximately 100 square miles called a ‘hundred’. One of these was the ‘Hundred of Adelaide’ upon which the city of Adelaide was established. McLean’s Adelaide 100 works to largely replicate the perimeter of the ‘Hundred of Adelaide’.

“Across thirteen councils, we have opened almost 70 per cent of it. It’ll be 132 kilometres when it is done. It’s a great trail, Jim and the board of volunteers at Walking SA have been working on it for many years, and we have just about finished it.”
Split into seven sections, currently open is Section 1A Kingston Park to Majors Road, Section 4B Monument Road Norton Summit to Newton, Section 5 Newton to Adelaide City, Section 6 Adelaide City to West Beach, and Section 7 West Beach to Kingston Park. These range in lengths and difficulties, ranging from 1A at 6.8km taking just 2-3 hours, all the way up to 4B at 21km taking 1 day to complete.
Still under construction and yet to open are Sections 1B Majors Road to Belair National Park, Section 2 Belair National Park to Stirling, Section 3 Stirling to Basket Range, and finally Section 4A Basket Range to Monument Road Norton Summit.

“It’s been very tricky to coordinate. Council consultation needs to happen all the time along the way and we’ve been fortunate that all the councils have seen the community benefit from having this loop trail in their council regions. It has already generated a stack of interest, to be fair more than I thought it would, and we think everyone is really excited.”
With only a few sections left to finalise, the Adelaide100 trail is set to become a must-explore experience for locals and visitors alike, offering breathtaking views and an immersive journey through the city’s natural beauty.
