On leaving Ulva Ferry, we drove to Fidden at the end of the Ross of Mull. Unlike the dark volcanic basalt found round Loch na Keal, the rock here was a red granite.

This beautiful red rock has been quarried for building such structures as the Skerryvore lighthouse, Iona Cathedral and further afield, Blackfriars Bridge, Holburn Viaduct and the Albert Memorial in London.
