Try to avoid Tor Head road out of Ballycastle towards the Giants Causeway unless you really like steep climbs and descents. It alongside Mamore Gap in north Donegal are the local 'iconic' climbs. There are also two on Kerry which will be hard to avoid on WAW - Conor's Pass and Healy Pass. Great views at the top of them all than make the climb worthwhile on a good day.Ooh, have I inadvertently mapped myself over the Causeway? Desperate to see it but yes, not the ideal riding surface. :-/
