Mount Barney looks like it was put there to be argued about. The rugged double summit rises to around 1,350 metres, the second-highest peak in south-east Queensland, and its bare rhyolite crags stand out above the softer farmland of the Scenic Rim like a fortress somebody forgot to finish. Geologists will tell you it is the eroded core of an ancient volcanic system; locals will tell you it has humbled plenty of overconfident walkers. Either way, it is part of the Gondwana Rainforests of Australia World Heritage area, which stretches along the border ranges between Queensland and New South Wales.
For a rider, the park is something to circle and admire rather than enter. Access is from the Rathdowney side and the Upper Logan roads, through cattle country where the lanes are narrow, the bitumen is sometimes patched and the creek crossings can flood after heavy rain. Cattle grids, wandering stock, kangaroos at dusk and the odd timber truck are your traffic. The Mount Lindesay Highway, the main road toward the border, has some good flowing sections, but the real pleasure is on the minor roads that fan out toward the ranges.
There are no services in the park itself. Rathdowney is a small village with the basics, and Beaudesert, a bit further north, is the place for a full tank, groceries and a proper choice of coffee. Boonah and Kooralbyn are closer as the crow flies but need a longer loop by road, so plan your fuel stops with care before heading out.
The landscape shifts as you climb from the valleys: open eucalypt woodland, grass trees on the dry slopes and pockets of rainforest in the gullies where creeks keep things damp. Bell miners ping in the trees near water, wallabies graze the paddock edges, and in spring the wattles turn whole hillsides yellow. The Logan River starts in these ranges as a clear little stream before it grows into something much larger downstream.
Autumn and winter are the kindest seasons here, with dry, clear days and cool mornings. Summer brings heat, humidity and spectacular afternoon storms that can turn a dirt shoulder into soup in minutes. Pull over somewhere along Upper Logan Road with the mountain filling your mirror and give it a moment; it is one of those shapes you remember long after the ride.
