A cache of superbly preserved structures from Dingle's ancient past including beehive huts, ring forts, inscribed stones and early Christian sites are a highlight of Slea Head, set against staggeringly beautiful coastal scenery. The landscape is especially dramatic in shifting mist, although it's obliterated when thick sea fog rolls in.
Dunmore Head is the westernmost point of the Irish mainland; just to its south is the picturesque cove Coumeenoole Beach. There are other good beaches at Ventry, Clogher and Wine Strand near Ballyferriter.
The signposted Slea Head Drive is a 50km loop that passes through the villages of Ventry, Dunquin, Ballyferriter and Ballydavid to the west of Dingle town, and takes in all the main sights. Including time for sightseeing, it's at least a half-days' drive or one or two day's by bike.
