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.

The “little nest” of Kenmare is part of the famed Ring of Kerry, making it a prime stop for a spot of lunch and a pint. But before you go on your merry way, check out the area’s Bronze Age stone circle, one of the largest in southwest Ireland. The peaceful glens and streams of Gleninchaquin make a wonderful backdrop for a picnic, which you can work off on a walk along the Kenmare section of the Beara Way.

Nice has a cosmpolitan Riviera vibe, and you'll enjoy exploring its fashionable boutiques and restaurants and sunning yourself on its popular beaches. (Just don't expect soft sand—these beaches have pebbles.) Walk up to Castle Hill for a beautiful view of the city, the Bay of Angels and of course, the bright blue water that gave the Cote d'Azur its name.
