Tourism Ireland have recently opened up a new tourist trail around the west coast of Ireland, called the Wild Atlantic Way, stretching from the north of Donegal all the way down to Kinsale in County Cork. The trail is 2500 km of coastline, which you can drive/walk/run/cycle/jog, all at once or county by county. The route is very well signposted and there are great suggestions and itineraries and maps on the website, to help people plan their trip.
It is hard to believe that a country as small as Ireland would have a coastline on its western side of 2500 km, when the direct route from Kinsale to Donegal is about 420 km, but if you have ever been to Ireland, and driven on the narrow, twisting country roads, you will be able to imagine what this route is like.
Here are a few photos taken at Coolmore Beach, in my little section of the Wild Atlantic Way, in County Cork. There is so much information on the whole trail on the Tourism Ireland website, it is well worth a visit if you are thinking of exploring in Ireland.
