Route Waypoint Map

The total ascent is 1,702 metres. Allow 7 hours to complete this 20.32 km route.

The hillphones service can inform you of stalking activities in the area.

Usually the shortest way to climb the mountain, making best use of tracks and paths to gain altitude. Route navigation requires map reading skills and an ability to navigate with a compass.

The information given here will enable you to annotate your map and plan your route. We do not give anecdotal descriptions on where to find the paths, worn by the feet of previous mountaineers.

Where the access routes are few or the ridge is narrow, paths are generally obvious. On open ground, following paths without using your compass may get you lost in poor visibility.

I climbed the Corbetts of Arran each on their own, and so didn't follow the route given, yet they're some of the best hills I have climbed on. As well as great views, they give you the option of taking the hard or easy route around - they aren't to be missed.
