Whether you come for skiing or summer fun, beautiful Sun Valley offers recreational activities galore in the spectacular Rocky Mountains of central Idaho. Most of the action takes place around the Sun Valley Resort and its two mountains: Bald Mountain, ideal for expert skiers or snowboarders looking for steep, challenging runs, and Dollar Mountain, with gentle slopes that are perfect for beginners. Off the slopes, more winter fun awaits: try dog-sledding through miles of white powder or spend an afternoon ice fishing in the Big Wood River. Warm up at the Ketchum/Sun Valley Heritage and Ski Museum which features an exhibit on the history of skiing and information about Ernest Hemingway's time in Sun Valley. Summer in Sun Valley offers just as many adventures. The Sawtooth Wilderness Area boasts over 200,000 acres of natural splendour, with opportunities for swimming, fishing, mountain biking, white-water rafting and more.

Plan to cross many bridges when in Cork. Ireland's third-largest city began life as an island and now spans both banks of the River Lee, with watery channels running beneath some of its main thoroughfares. The best way to experience this hilly southern seaport is on foot, following the signposted walking tour past St. Finn Barre's Cathedral and the riverside quadrangle of University College up the hill to red and white Shandon Church. Along the way, you'll meet plenty of the city's talkative residents.

Isolated from the rest of Maui by a 52-mile winding drive through coastal rainforest, Hana is an unspoiled beauty dangling from the island's northeastern tip.

Soak up the tropical splendor on beaches with red or black sand. Winter and spring bring humpback whales, visible from Hana Beach County Park.

Founded by the Berbers in the 2nd millennium BCE, the city of Tunis has been controlled by Phoenicians, Romans, Arab Muslims, the Ottomans, the Spanish, the French and the Germans, finally achieving independence as the capital of Tunisia in 1956. This history has made Tunis a mélange of ancient and modern cultures. The medina is a network of narrow alleyways, mosques, mausoleums, palaces and a souq where shoppers haggle over the price of everything from filigreed gold to inexpensive souvenirs.
