The coastal jewel of Javea is bookended by rocky headlands and is a prime example of old world meets modern energy. The "old town" district is filled with remains of walls built to keep out pirates, as well as a 14th-century church. Visit the beautiful white-sand Arenal beach, brimming with shops, restaurants and, in the summer, hopping beachside bars and nightclubs.

A popular gateway to the Balearic Islands, Denia is a worthy destination in its own right. The port city exudes culture at every turn: an ancient Moorish castle overlooks idyllic beaches, archaeological museums, and authentic eateries, while Mt. Montgó looms in the backdrop.

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

You may have to fly into Ibiza's airport to get to Formentera, but a holiday here is the antithesis of a wild week in Ibiza. You'll reach Formentera by ferry, and you'll find a quiet, peaceful little island with natural beauty to spare. Rent a scooter or bike to take you from beach to beach.

Stroll Las Ramblas and enjoy Barcelona's unique blend of Catalan culture, distinctive architecture, lively nightlife and trendy, stylish hotels. You'll find Europe's best-preserved Gothic Quarter here, as well as amazing architectural works by Gaudi. La Sagrada Familia, considered Gaudi's masterpiece, is still under construction (your entrance fee helps to fund the project). Feel like a picnic? Look no further than the rambunctious La Boqueria market, where you can stock up on local delicacies.

It’s nicknamed the Eternal City for a reason. In Rome, you can drink from a street fountain fed by an ancient aqueduct. Or see the same profile on a statue in the Capitoline Museum and the guy making your cappuccino. (Which, of course, you know never to order after 11 am.) Rome is also a city of contrasts—what other place on earth could be home to both the Vatican and La Dolce Vita?

Belgrade's long and storied history is suggested by its architecture, which varies from Byzantine and Ottoman to neoclassic and romantic buildings in the older neighborhoods, and from Art Nouveau to brutalism and neo-Byzantine design in New Belgrade. The city's many theaters, museums, monuments and opera houses boast a deep and fissured cultural life while the beaches and rivers attract sunbathers, sports enthusiasts and partygoers on the popular floating river barges that serve as nightclubs.

Sosua is everything you want a beach town to be. Clear waters teem with coral, perfect for snorkeling and diving. Above sea level you’ll find multicolored sands lined with beach shacks. This small enclave of the Dominican Republic was once a haven for Jewish refugees. Historic sites and synagogues offer great perspective on Sosua’s postwar identity. On a lighter note, a community of ex-pats helps fuel a boisterous, international nightlife scene.
