Hike overview
The Themeda Circuit offers a moderately challenging 3.6-kilometer exploration within Mount Osmond Reserve, South Australia. This grade 3 hike, suitable for most walkers, takes approximately 1.5 hours to complete and traverses a combination of terrains.
Beginning at the intersection of Sherwood Terrace, Caithness Avenue, and Hayward Drive, the circuit initially follows a single-track walking trail off Hayward Drive. This section winds its way up a steep hill using a series of switchbacks before entering Mount Osmond Reserve proper. The trail then progresses along Gleeson Ridge until meeting the Old Bullock Track. Finally, the descent utilises a fire track, leading you back to the starting point in Themeda Reserve.
It's important to note that some sections of this trail are shared with cyclists. Be aware of your surroundings and practice courtesy while navigating these shared pathways.
The Themeda Circuit forms part of the Burnside Walks network, a collection of well-marked trails across the reserve. Regular signage and numbered checkpoints ensure easy route following, further supported by a detailed walking map available for reference.

About the region
Situated just 8 kilometers southeast of Adelaide, Mount Osmond Reserve offers a welcome escape into nature. Managed by the City of Burnside, this open space reserve boasts a network of walking trails that cater to hikers and cyclists of varying abilities.
Several access points are conveniently located around the reserve. These include Gate 1 on Waterfall Gully Road, Gate 2 on Dashwood Road, Gate 3 on Hayward Drive, and Gate 4 on Old Bullock Track (accessible from Mount Barker Road). Notably, Gate 4 also provides a connection to Cleland National Park, Eagle on the Hill, and Measday's Lookout. Additional access points, like the one on Greenhill Road, are available depending on your chosen walking or cycling route.
The land comprising Mount Osmond Reserve holds deep significance for the Kaurna people, the traditional custodians of this area. Their ongoing connection to this land is acknowledged and respected.
Prior to European settlement, the Mount Osmond area served agricultural purposes. While the steep slopes weren't ideal for crops, they provided suitable grazing land for livestock. Additionally, some quarrying activities were undertaken in the vicinity.
Interestingly, the Mount Osmond Reserve was originally acquired by the Highways Department in the 1940s for a planned arterial road. However, since the late 1980s, it has been managed by the National Parks and Wildlife Service South Australia (NPWSA) on behalf of the Department for Planning. Recognizing its importance as a scenic link between Beaumont, Mount Lofty, Cleland National Park, and the Mount Osmond Golf Course, the area was ultimately preserved as open space for all to enjoy.
