Starting from the car park at the corner of Gill Terrace and the South Eastern Freeway (near the Old Tollgate), Glen Osmond, this circuit walk lets you see the Glen Osmond mine chimney, mostly via the Old Toll Gate Access Track and Mt Osmond Fire Track. The Toll Gate Circuit is a picturesque walking track at the city's southeastern corner, offering stunning views of the city itself and the ocean. The journey takes visitors beyond the Glen Osmond mine chimney and through Danthonia Reserve, where they can see the stone chimney, which was the flue for a smelter located north of the adit. Along the way, hikers can enjoy the lush greenery and may even spot a koala. The track is well-signed and has numbered checkpoints. It is also a part of the Burnside Walks network. However, visitors should be careful of cars while walking along Gill Terrace, as a big part of the road doesn't have a footpath next to it. Let us begin by acknowledging the Traditional Custodians of the land on which we travel today, and pay our respects to their Elders past and present.
