Iveragh peninsula

More commonly known as the Ring Of Kerry. Undoubtedly the busiest section of the SWI500 with an inordinate number of tour buses setting out from Killarney. However travel in a clockwise direction,  you'll not get stuck behind them and you'll enjoy a mix of challenging & fast roads and fantastic views. A 179Km long and full day out.

Two gpx files are available here ; one for the ring of Kerry itself and one for a challenging route over 3 mountain passes.
