Sitting at the northernmost corner of Virginia in the Shenandoah Valley, Winchester offers visitors the chance to explore historical sites, museums, vineyards, farmers' markets, and tree-lined Old Town streets once wandered by the likes of George Washington and Stonewall Jackson. The fruitful fields of the surrounding Frederick County have earned the area the title "apple capital of the world," with the city hosting the Shenandoah Apple Blossom Festival annually for almost a century.

The farther you go from Grand Cayman's busy docks, the more peace and quiet you'll find. At Stingray City (actually a sandbar), stingrays swim alongside you in the tranquil waters. Closer to town, travelers report finding some of the best massage and spa services anywhere in the Caribbean.

Mayan ruins tower over the sea in Tulum. The formerly walled city was one of the last to be built by the Mayans, and its archaeological sites are incredibly well preserved. Take a break from the beach to visit El Castillo, the Temple of the Frescoes, and the Temple of the Descending God. Explore an underground river under a canopy of stalactites in the sacred caverns of LabnaHa Eco Park, or dive into Cenote Dos Ojos to snorkel inside of caves in the middle of a forest.

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.
