Slower but much more interesting road from Tarbert via Kennacraig then down to Carradale then to Campbelltown. Single track with passing places and some tricky bends to negotiate - sharp, twisty and steep. Looking over Kilbrannan Sound to Arran is georgeous and high road position gives great view. Summer ferry to Lochranza on Arran leaves from Claonaig short distance after start of this route. Great campsite at Carradale but try to keep this a secret.
