A narrow winding road, 15 miles long, leads south from Campbeltown to the Mull of Kintyre, passing good sandy beaches near Southend. This remote headland was immortalised in the famous song by Paul McCartney and Wings; the former Beatle owns a farmhouse in the area. From the road's end, a 30-minute steep downhill walk leads to a clifftop lighthouse, with Northern Ireland, only 12 miles away, visible across the channel. Don't leave the road when the frequent mists roll in; it's easy to become disoriented.
