About the Walking Trail
The Shoreline Loop is one of the two hardest and longest of the four trails in the newly opened Happy Valley Reservoir. The reservoir and trails were opened to the public on 11 December 2021.
The Shoreline Loop is a 11km 3 hour trail, rated as Grade 4, which means “Very steep hills. Some bushwalking experience required.” The trails are suitable for children to ride bikes on, but do refer to the bike grade ratings on signs.
The Boundary Loop and Shoreline Loop are very similar, the difference being in the south eastern corner and southern side of the reservoir, the Shoreline Loop follows closer to the shore, whilst the Boundary Loop sticks closer to the boundary fence. North of the dam wall and carpark on Chandlers Hill Road, the trails exit the reservoir reserve and follow a nice treed corridor parallel to the road. Continuing north, where the trail meets South Road it re-enters the reservoir reservoir, and for a short section past the solar farm is bound in a short narrow corridor. Passing the intersection of South Road and Black Road, there is a connection across the pedestrian lights between Happy Valley Reservoir and Glenthorne National Park-Ityamaiitpinna Yarta. As the trail follows some of Black Road, it follows the boundary fence with pine plantation on the reservoir side. The trail in these northern section of the reservoir reserve are avoiding the filtration plant and solar farm.
The trail commences from the main reservoir trailhead and carpark, off Chandlers Hill Road, from the roundabout with Kenihans Road. This carpark is accessible to wheelchair users, but these two trails are not wheelchair friendly due to hills and some rougher track sections. There are toilets, picnic shelters and bbqs at this trailhead. The trail can also be accessed from the carpark near the dam wall, off Chandlers Hill Road, as well as the carpark on Manning Road for Minkarra Park. There are also a couple of other access gates scattered around the reservoir boundary.
The trail is marked with green trail markers.
You can view all trails on our Happy Valley Reservoir page.

Dog walking not permitted
Dogs are not permitted at Happy Valley Reservoir or at any of South Australia’s other reservoir reserves, regardless of whether they are on a leash, as they can carry harmful bacteria and viruses that can easily contaminate the water and are a risk to the safety of the drinking water. Dogs also pose a threat to local native birds and wildlife. Assistance animals are excepted.
