Three Brothers Road is a short gravel and dirt route that climbs up into the hills toward the Lake Onslow area in Otago. The track gains elevation steadily, opening up to the wide, tussock-clad high country that characterises this part of the region. It's a straightforward run on a formed surface, making it an easy way to reach the remote, open landscapes around Lake Onslow without demanding technical driving. Expect sweeping views back across the surrounding hills as you ascend. Conditions can vary with the weather given the exposed, elevated setting, so come prepared for the high-country environment. A useful connection for those heading into the Onslow backcountry.
