Welcome to Mizen Head Peninsula
Even here the Mizen (rhymes with 'prison') isn't done. Increasingly narrow roads head further west to spectacular Mizen Head itself, and to the hidden delights of Barleycove Beach and Crookhaven. Without a decent map you may well reach the same crossroads several times.
Heading back from Goleen, you can bear north to join the scenic coast road that follows the edge of Dunmanus Bay for most of the way to Durrus. The R591 heads north through Durrus for Bantry, while the L4704 turns west to Ahakista and the Sheep's Head Peninsula.
