Climbing the Twistin Hill
From Crianlarich, drive south on the A82 into Glen Falloch and start from the A82 layby in Glen Falloch. Take the path from the end of the layby to the railway underpass, cross the River Falloch and follow the track south, then turn right up the grassy flank of Sron Gharbh. A clear path follows the winding Twistin Hill ridge, crossing a deep cleft on a couple of steep steps, to the summit. The route is Class 2. The field and lower slopes are very boggy, and the rocky steps are slippery when wet. Usually combined with Beinn a' Chroin across the Bealach Buidhe.
