This Corbett boasts some of the steepest hill slope in all of Scotland. An Dun (827m) is best appreciated from the south as you approach on the remote Gaick Pass which takes you some 9km from the A9. A mountain bike can be a valuable aid for hillwalkers intent on this hill. Consult a guidebook for further details on access and hazards. For experienced walkers, the summit offers a superb viewpoint of the Gaick Pass which cuts through the surrounding moorland.
