Overview
In the southern Flinders Ranges, where the flat agricultural plains of the mid-north rise abruptly into ancient, weathered ridgelines, Mount Remarkable National Park offers some of the most rewarding bushwalking in the state. The Sugar Gum Lookout Hike is an 8-kilometre return walk that begins with a gentle stroll along the valley of Mambray Creek before climbing steeply to a lookout perched among stands of sugar gums on the upper ridge. The contrast between the easy valley walk and the demanding climb makes this trail feel like two walks in one — and the views from the top make every step of the ascent worthwhile.
The trail takes its name from the sugar gums that dominate the upper ridgeline. These elegant eucalyptus trees, with their smooth, salmon-pink bark that peels away in patches to reveal cream and grey tones beneath, are among the most beautiful trees in the Australian bush. Standing among them at the lookout, with the ranges spreading out in every direction, is one of those moments that defines why people walk in the Flinders.
The Walk
Along the Valley
The first half of the walk follows Mambray Creek through a corridor of magnificent river red gums. The going is flat and easy, the path shaded, and the birdlife abundant. Adelaide Rosellas flash through the canopy, kookaburras call from the upper branches, and yellow-tailed black cockatoos pass overhead in noisy groups. Western grey kangaroos are commonly seen grazing along the creek flats, and echidnas trundle through the leaf litter in the quieter sections.
The Climb to the Lookout
The trail leaves the valley floor and begins a short but strenuous ascent up the ridge face. The gradient is steep and sustained, climbing through changing vegetation as you gain elevation. Blue gums and drooping sheoaks give way to the sugar gum woodland of the upper slopes, and the views begin to open up behind you. The lookout sits at the top of the climb, with a natural rock platform that provides a perfect resting spot. The panorama from here extends across the park to the north, with the Flinders Ranges unfolding in layers of blue and purple, and to the west, where the flat plains stretch towards Spencer Gulf.
Connecting Trails
The Sugar Gum Lookout Hike is part of a larger trail network within the Mambray Creek area. The Wirra Water Loop provides a gentle warm-up walk along the creek. The Daveys Gully Hike offers a more demanding alternative route through a scenic side valley. And the Alligator Gorge trails, accessible from the eastern side of the park, provide a completely different walking experience through a dramatic narrow gorge.
Planning Your Visit
Mount Remarkable National Park is located approximately 45 kilometres north of Port Pirie, accessed from National Highway One via the Mambray Creek turnoff. The Mambray Creek Campground has powered and unpowered sites, toilets, barbecue facilities, and a small information shelter. A park entry fee applies. The best time to visit is between April and October. Summer temperatures can exceed 40°C, so if walking in warmer months, start at first light and carry extra water. Allow at least 2 litres per person for this walk.
The Sugar Gum Lookout Hike earns its reward. The gentle valley walk lulls you into a rhythm, and then the climb demands your full attention — but standing among the salmon-barked sugar gums at the top, with the Flinders Ranges spread out before you, the effort dissolves into one of those pure, quiet moments that only bushwalking can deliver.
