The tour The 179km circular loop road(N70, N71 and R562) starts from Killarney in County Kerry, south western Ireland, heading around the Iveragh Peninsula through Kenmare, Sneem, Waterville,Cahersiveen and Killorglin. As the narrow roads make it difficult for tour coaches to pass, buses run in an anti-clockwise direction, travelling via Killorglin. This trip is usually done in a day.
