The Mount Adams Wilderness area covers some 46,587 hectares and there are no tracks, bridges, or huts provided. There is a marked route trampers can take from State Highway 6, north of Whataroa, to the bush line that takes five hours.
It involves a river crossing and a steady climb for three hours to a tussock-covered ridgeline.
According to the Department of Conservation, it is suitable for well-equipped and experienced backcountry trampers and climbers only; navigation and survival skills are required.
