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.

Perched on the hem of the Atlantic in Ireland's southwest, charming Dingle looks out over Dingle Bay to the Blasket Islands. Chock full of friendly pubs where live traditional music plays, the Irish-speaking area fills to the brim with tourists on weekends and through summer. Another regular visitor to Dingle's Gulf Stream-warmed waters is Fungi, the dolphin, the town's unofficial mascot. Popular tourist attractions include the beaches, Mount Brandon and Ballydavid and Ballyferriter villages.

Situated at the foot of the western Pyrenees near the French border, Spain's Basque country comprises three provinces: Guipúzcoa and the popular beachfront capital of San Sebastian; Viscaya, where capital Bilbao houses the jaw-dropping Gehry-designed Guggenheim Museum; and Alava, whose capital Vitoria teems with medieval architecture. Running with the bulls at Pamplona and drinking rioja from local wineries add to the region's exotic romanticism. Travel in early summer and autumn to avoid the crowds.
