Don your most comfortable shoes for Killarney, where town trails offer history lessons and country walks traverse Ireland's first national park: 26,000 acres of woodlands, sandstone mountains and low-lying lakes. In the town centre, Killarney House and Gardens provide a break for urban explorers. Renowned Muckross House, with its 15th-century abbey ruins and massive yew tree, is just outside the town. If your feet wear out, take in Killarney National Park's legendary scenery from a boat trip from Ross Castle.
