If you are walking this route in one day it can be quite challenging! Begin from the ferry terminal in Lochranza and follow the old postman's footpath through the birchwoods high above the road before descending to Catacol Bay. Now commence a long stretch on generally quiet coastal road to Pirnmill village. After Pirnmill it's a rugged trek along the coastline away from the road, which is rejoined at Imachar. Then another long stretch of road walking leads down to the coast, passing the spectacular King's Cave and dominating cliffs of Drumadoon Point to cross the sandy beach of Blackwaterfoot.
