Mt Osmond Trails

Mt Osmond, only around 8 km south-east of the Adelaide CBD, offers steep and rocky mountain biking across the slopes of Mount Osmond Reserve, with connections into Cleland National Park, Chambers Gully and Eagle on the Hill. Rather than a purpose-built bike park, the area combines shared-use tracks, fire trails and designated MTB lines across Adelaide’s Hills Face. Expect sustained climbing, loose and rocky terrain, fast natural descents and some technical sections, all backed by impressive views across Adelaide and the plains towards the coast. One of the key routes through the area is the historic Old Bullock Track, which links Mount Osmond with Eagle on the Hill near Measday’s Lookout and provides access towards the wider Cleland trail network. The Mount Osmond Reserve tracks are officially classified as Grade 3 shared-use walking and cycling trails, with some sections becoming particularly steep and rocky. Riders can use the network to build larger loops incorporating nearby Chambers Gully, Wine Shanty Track and Cleland National Park, making Mt Osmond a useful gateway into a much bigger Adelaide Hills MTB adventure. For riders looking for more gravity-focused terrain, the wider Mt Osmond riding area also contains established MTB descents such as Bullock Track DH, a blue-rated downhill-only trail, and WC Downhill, which features jumps, drops, rock gardens and steep technical sections. These trails are a significant step up from the reserve’s easier shared-use riding and are better suited to confident mountain bikers with good technical skills. RTS Tip: Mt Osmond is a mixture of shared-use tracks, designated cycling routes and trails where cycling may not be permitted, so download a current map and follow local signage rather than assuming every visible singletrack is bike legal. Be prepared for steep climbing and loose rock, give walkers plenty of space on shared trails, and if you’re chasing a bigger ride, link Old Bullock Track into Chambers Gully and Cleland for a brilliant Adelaide Hills loop.
