From urban beaches to epic nightlife, Alicante offers a Mediterranean mix of action and relaxation. Add in a palm-lined esplanade snaking along the harbor and a Moorish castle looming above, and it’s one of the most dynamic spots on Spain’s sun-drenched Costa Blanca.

Bask on four miles of golden beaches, hit the Mediterranean Sea on water skis or stroll along Benidorm's promenade and revel in its seaside charms; it's a true Spanish beauty of the Costa Blanca. Originally a fishing town, the city's historic center wows with its blue-domed 18th-century church and picturesque alleyways. Panoramic views reward those who climb into the surrounding Canfali hills, and nearby rocky coves reveal underwater riches for scuba enthusiasts. End a day in the sun with a feast of local seafood.

Coastal Calpe seems straight from a postcard, with a dramatic rocky headland and palm-dotted beaches lapped by Mediterranean waters. Once an ancient fishing village, the Costa Blanca town mixes Roman ruins and scenic nature parks with plenty of modern urban comforts.

Travelers generally come to Bilbao to see the Guggenheim—some for the art inside, but many for the amazing building itself.

Brigitte Bardot frolicked on the beaches of St. Tropez in the '50s; now it's the playground of rap stars and international socialites.

Diddy, take heart: you'll find a few family-friendly, public beaches where the sun, sand and waves are just as fabulous.

In Vienna, the coffee house isn’t just a hangout: it’s an institution.

Once a shipbuilding city, Newcastle's flashier claim to fame is nightlife. Throw in a heap of premium restaurants serving foods from all over the world and it's no wonder young partiers choose to blow their hard-earned (or not-so-hard-earned) cash in Newcastle. While these amenities are certainly a draw for the hipsters and culture-seekers, it's the locals that make Newcastle a truly special place to visit. "Geordies," as they are often called, embody the pride, industriousness and resilient spirit of their city.

This 32-mile-long "Queen of American Lakes" is chock-full of lodging, attractions, eateries and just about any form of recreation you can name. A significant player in American history, Lake George is the site of two great forts, Fort William Henry and Fort Ticonderoga, both open to the public. Before plunging into the myriad activities in this family-friendly town, start off with a relaxing lake cruise to learn about the area. Then, take your pick of recreation: parasailing, fishing, diving, jet skiing, hiking, golfing, minigolf, horseback riding and more. If you've got kids in tow, you can't get away without visiting the Great Escape and Splashwater Kingdom, New York's largest amusement park. Hikers gravitate to the international trail system or Prospect Mountain, which offers panoramic views from the top; for an easier way up, hop on the tram. Among the cleanest and clearest of major U.S. lakes, Lake George is as splendid today as when Thomas Jefferson described it as "...without comparison, the most beautiful water I ever saw."
