Rich in relics from early European settlement, Horsnell Gully and Giles Conservation Parks attract bushwalkers and heritage enthusiasts alike. Venture through steep gullies and wooded hillsides on sections of the great Heysen and Yurrebilla trails, admiring historic sites and stunning views of the surrounding region. 


Take a bushwalk through the steep gullies in the picturesque Adelaide Hills to discover the history of Horsnell Gully and Giles Conservation Parks. Both the Heysen and Yurrebilla trails wind their way through these parks, offering stunning views of the surrounding region.

Named after the state Governor's coachmen, John Horsnell, relics and reminders of the Horsnell family property still remain. Along the signposted walking trails, you will find the remains of a large homestead, including the coaching sheds, stable and cowsheds. The original garden of the Horsnell property is located at the start of the walking trail, marked by elm trees, plum trees and orange trees.

There is an extensive network of trails within both parks, with two main hiking loops in Horsnell Gully Conservation Park.

Pests and diseases

Phytophthora (fy-TOFF-thora), otherwise known as root-rot fungus, is killing our native plants and threatens the survival of animals depending on plants for food and shelter.

This introduced fungus can be found in plant roots, soil and water. Help stop the spread by using hygiene stations, staying on tracks and trails and by complying with all Phytophthora management signs.

Traditional owners

Aboriginal South Australians are the first peoples of our State and have occupied, enjoyed and managed these lands and waters since the creation. For SA's First Peoples, creation ancestors laid down the laws of the Country and bestowed a range of customary rights and obligations to the many Aboriginal Nations across our state. 

Aboriginal peoples' oral histories and creation stories traverse the length and breadth of Australia’s lands and waters, including South Australian Parks. These stories interconnect land and waters with complex meaning and values and hold great cultural significance. We recognise and respect Aboriginal people's ownership of their stories and that they hold rights and obligations to care for Country. It is through these rights and cultural obligations and a shared goal to protect the environment for generations to come that DEWNR is committed to meaningful collaboration and involvement with Aboriginal peoples in the management of our shared parks.

See and do


Bushwalking is a fantastic way to connect with nature, keep fit and spend time with family and friends. 

South Australia's national parks feature a range of trails that let you experience a diversity of landscapes. Our trails cater for all levels of fitness and adventure and our classification system makes it easy to select an experience suitable for you.

Both the Heysen and Yurrebilla trails wind their way through these parks, offering stunning views of the surrounding region.

Moderate hikes

  • Old Coach Road Hike (1 hour one way, 2km)

    Begin from the gate at the end of Coach Road in Skye or at gate 3, Horsnell Gully Conservation Park. Walk along what was once the principal road into Adelaide from the east during the 1870s and 1880s. There was a coach gate located on the highest point of ‘Coach Hill’, which is known today as the suburb of Skye. The driver blew a trumpet to tell the settlers that he had been through the gate and they had to climb up to close it. Near the spot where the power lines cross Coach Road, there was a hut for a ‘team’s keeper’ who kept fresh horses for the coaches.

Hard hikes

  • Main Valley and Rockdale Hill Hike (2 hours return, 4km)

    Start at the car park, Horsnell Gully Conservation Park. Follow the Main Valley trail and walk beneath majestic river red gums and South Australian blue gums to the waterfall. Keep an eye out for koalas in the tree tops and a variety of woodland birds in the trees and foraging in the undergrowth. Traverse the waterfall - beware of slippery rocks - and continue in a south-easterly direction to the Mount Lofty to Norton Summit trail. Follow this trail north to Rockdale Hill. From here, traverse along Rockdale Hill Track, which gradually descends into the scenic valley, before turning west and traversing a ridgeline, providing excellent views of parts of the city of Adelaide. The trail then descends back into the main valley to the car park.
