(S) From Beinglas head North. keeping the River Falloch on your left. The route bends to the right following the river and the main A82 road.
(1) Go through a small wood to reach the Falls of Falloch in Glen Falloch. The path stays with the river, crossing to the other side near Derrydaroch.
(2) Our route continues to follow the river and the road, crossing the railway and the road near Carmyle Cottage. Climb slowly left to join the Old Military Road past Keilator, Caisteal Ghriogair, through Bogle Glen and bear left through the forest near Crainlarich keeping North-West-North.
(3) Once out of the forest, cross over the railway and turn left along the A82 road. Take the path off to the left, over the River Fillan (past the remains of St. Fillan's Church), past Kirkton Farm and a cemetary to reach Auchtertyre.
(4) Cross the stream Allt Auchtertyre and head back to the river, crossing the main A82 road. Stay North of the river to Dalrigh, where the route swings North again following Crom Allt and the railway.
(5) Go through Tyndrum, staying with the stream, crossing the road and following the railway.
(6) Cross the railway to pick up the Old Military Road again as the shadow of Beinn Odhar looms large to the right at 901m above sea level.
(7) Cross the railway again to follow Allt Coire Chailein as far as the bridge at Allt Kinglass.
(8) Cross the bridge and bear left in a North-West direction following the railway (to the right) and the river (to the left). Beinn Dorain looms ominously in front and to the right after the bridge, at 1,076m above sea level it's probably best for us to follow the route, skirting the crags rather than having to climb the mountain.
(9) Cross the railway again to follow the wall a little higher up the slope. Come back down again to cross the railway at the station and walk into the Bridge of Orchy.(E)
