The alternative route starts in Glen Strathfarrar to the north at the hydroelectric power station in Gleann Innis (grid reference ), reached by a 17-mile drive from Struy along a private road; the locked gate at the entrance to this road is opened at specified times to give access to vehicles. From the power station a stalkers' path leads to the Bealach Toll an Lochain between An Riabhachan and Sgurr na Lapaich, from where there is a further climb west of over 300 metres to reach the summit. A return to the power station can be made over Sgurr na Lapaich and Càrn nan Gobhar.
