The Vitrified Fort

The tour goes over Sgorr Chalum,  5 km due West of the summit of Ben Nevis, the highest mountain in Britain, and provides wonderful views of the Ben and of Glen Nevis below. The route takes us past Dun Deardail, a Vitrified Fort where fire caused the rocks of the building to fuse together.
