Dingle Peninsula, Killarney
Of the five peninsulas in Western Cork and Kerry counties, Dingle peninsula is the one I enjoyed the most. In good weather it's a cycler's paradise, with plenty of archeological sites and wonderful coastal landscapes.
See the travelogue for some of my favourite pictures!
The Dingle Peninsula. Most tourists do see this area but do it too quickly. Take your time, walk around a little, say Hi to a local sheep and watch the sunset!
