the lower reservoir has a nice flat road next to it, a welcome relief after the lumpy roads that lead to it from either direction.

Gap Road. This was the first track to enable horse-drawn carriages to cross the mountain range. It's thought to be a Roman road, although no archaeological evidence has been found as yet. Turn right onto the gap road and follow this route all the way back to the car park, and to your starting point.
