Most visitors to Fiumicino arrive by plane and immediately continue on to Rome, but—in addition to being home to Italy’s busiest airport—the coastal town doubles as a beach resort during the summer months. There’s also Ostia Antica archaeological site, which is just a short drive away.

Corsica is a weird and wonderful island, replete with gorgeous beaches and breathtaking mountains. Bonifacio, a harbor city on the southern tip, is rich with history.

Biking, hiking, rafting and diving are popular activities.

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.

The pillars of Islam state that all Muslims with the means must undertake Hajj, a pilgrimage to Mecca, once in their lifetime. Those who visit the holy city are rewarded not just by proximity to landmarks and religious sites crucial to the religion, such as the Masjid Al Haram (Holy Mosque), the Mountain of Light, the Black Stone and the Well of Zamzam, but with the forgiveness of all their sins.

Walk the Freedom Trail the first time you visit Boston and you'll quickly get a sense of this coastal city's revolutionary spirit and history.

You can't claim to have experienced real Boston culture, though, until you've watched a Red Sox game from the bleachers.
