The Mark Bonnin Walking Trails offer a range of walking routes suitable for all abilities within Hiltaba Nature Reserve. Situated approximately 15 kilometres from the reserve's homestead, the trailhead can be easily reached via a short detour from Iron Knob/Yardea Road. This diverse trail system features three distinct paths, each highlighting a unique aspect of the reserve's rich landscapes.
The Green Trail, a 2.7-kilometre return journey, is perfect for a shorter exploration. It winds past picturesque waterfalls and provides an easy walk through native vegetation, including Grevillea and Acacia. For a more substantial trek, the Blue Loop Trail extends for 8 kilometres. This challenging circuit traverses a rocky gorge, allowing hikers to appreciate the rugged beauty of the terrain. The loop culminates at the starting point, offering a full immersion into the natural surroundings.
For experienced hikers seeking a more demanding adventure, the Red Loop Trail extends from the Blue Trail, adding an extra kilometre and ascending from the gorge to the Lookout. This route incorporates steeper and more rugged terrain, including the climb to Mark Bonnin Peak. The Lookout rewards hikers with breathtaking panoramic views across the entire nature reserve.
Throughout these trails, hikers will encounter a variety of ecosystems. Expansive grasslands with swaying casuarinas contrast with unique mallee scrub habitats teeming with hardy native plants. Rocky outcrops and gorges reveal the ancient geological history of the reserve.
While the Red Loop offers exclusive access to the Lookout vantage point with its spectacular views, all visitors can reach the Lookout by car or via a separate walking track. This ensures everyone can enjoy the scenic beauty and panoramic vistas, regardless of their chosen walking trail.

Encompassing 78,000 hectares on the Eyre Peninsula, Hiltaba Nature Reserve borders the Gawler Ranges and offers vital sanctuary for a diverse range of species. The reserve's significance is recognised through the presence of over 40 state-listed and nine nationally listed threatened species, including the Yellow-footed Rock-wallaby, Short-tailed Grasswren, and the Desert Greenhood Orchid.
Originally a pastoral lease known as Hiltaba Station, the land was acquired by the Nature Foundation in 2012. The area has a rich cultural history, having been inhabited by the Barngarla, Kokatha, and Wirangu peoples, collectively known as the Gawler Ranges Aboriginal People, for at least 30,000 years.
Distinctive granite hills rise above sprawling plains of varied grasslands and woodlands, creating Hiltaba's unique geological landscape. This diversity of habitats attracts a rich tapestry of birdlife, from the endemic Gawler Ranges Short-tailed Grasswren to the imposing, one-and-a-half-metre tall Australian Bustard. Birdwatchers and nature enthusiasts alike will be captivated by Hiltaba's remarkable fauna.
Visitors can explore the reserve's beauty via a network of nature drives or walking trails, offering the chance to witness the magnificent granite hills and diverse plant communities. Whether you choose a day trip or opt to stay at the campsite or other available accommodation, Hiltaba Nature Reserve provides an unforgettable experience.
