I drove to the west end of Stronuich Reservoir in Glen Lyon, which can be reached from B846 west of Aberfeldy or across the Lawers Hill Road from the A827 east of Killin, and parked at the west side of a cattle grid. I then walked across it and climbed north-east on rough vegetation following the line of a stock fence.

A gate was crossed and from there I headed for the Allt Cashlie crossing it just below a newly constructed dam.

It was then a steep climb, latterly up a grassy gully avoiding most of the rocks, to reach the grassy summit of An Grianan, a Hump and Corbett Top.

There was a cold wind blowing so on reaching the summit cairn I made the easy descent to the col with Stuchd an Lochain then headed for this Munro. The underfoot conditions were fairly good with the final climb on an eroded and fairly steep path.

On visiting the summit cairn I located a sheltered area for a snack then returned down the south-east ridge. I continued along this ridge where there were some old metal fence posts and ascended the Munro Top, Sron Chona Choirein.
I then descended south and climbed the Sub Simm, Meall Dubh, visiting a couple of points as I couldn’t tell which was the highest.

Thereafter I continued south on a fairly steep descent on grassy vegetation to reach the gate used earlier in the day and returned to the start.
