Home to Windsor Castle, the second residence of Queen Elizabeth II, Windsor is a popular day-trip destination from London. Those who tarry in the riverside town fill their time wandering the cobbled streets, popping in and out of the luxe boutiques, restaurants, and tea shops that tumble down toward the Thames River.

Just west of London, Reading offers redbrick Victorian buildings, medieval ruins, a thriving university, and pretty waterside walks along the Thames River. Its student community and annual rock-music blowout—the Reading Festival—add an offbeat edge.

Londoners have been traveing to Brighton for beach getaways ever since the railway arrived here in 1841. The pebbled beach, Brighton Pier's amusement arcade and the Royal Pavilion are the main sights, but you'll also find hundreds of pubs and clubs catering to an energetic crowd.

In the "city of dreaming spires," academia takes center stage. Gaze out at Oxford's world-famous university from the top of Carfax Tower before heading into the city's pedestrian-friendly streets. Follow your nose to the Covered Market for the makings of a picnic to enjoy at Headington Hill Park. Mix the historic and modern with visits to the 12th-century village church of Iffley and trendy Cowley's ethnic shops and music venues.

Southwest of London is Southampton (Soton to the locals), a metropolitan area centered around the port. However, tucked away on the side streets are ancient gems such as the Tudor House, Mottisfont Abbey, and "God's House," a museum located in a tower in the medieval wall. The ultra-modern Sea City Museum celebrates Southampton's seafaring past and the RMS Titanic. Looking for nightlife? Travelers can dance the hours away with bars, clubs, and live music, all accessible by public transportation.

Lingering over pain au chocolat in a sidewalk café, relaxing after a day of strolling along the Seine and marveling at icons like the Eiffel Tower and the Arc de Triomphe… the perfect Paris experience combines leisure and liveliness with enough time to savor both an exquisite meal and exhibits at the Louvre. Awaken your spirit at Notre Dame, bargain hunt at the Marché aux Puces de Montreuil or for goodies at the Marché Biologique Raspail, then cap it all off with a risqué show at the Moulin Rouge.

You've probably heard that Guinness tastes better in Dublin (fresh from the factory), but what you may not know is that Dublin is a perfect destination for the whole family. No, we're not suggesting you let the kiddies drink a pint. Instead, take them to the Dublin Zoo, to feed the ducks in Stephen's Green or on a picnic in Phoenix Park. Scholars enjoy walking in the literary footsteps of such writers as Yeats and Joyce, while discerning shoppers have their pick of designer boutiques.

Barcelona feels a bit surreal – appropriate, since Salvador Dali spent time here and Spanish Catalan architect Antoni Gaudí designed several of the city’s buildings. Stepping into Gaudí’s Church of the Sacred Family is a bit like falling through the looking glass - a journey that you can continue with a visit to Park Güell. Sip sangria at a sidewalk café in Las Ramblas while watching flamboyant street performers, then create your own moveable feast by floating from tapas bar to tapas bar.

So many of Madrid’s buildings look like castles, you’ll think you’ve stumbled into a fairytale. Even City Hall is astounding, with its white pinnacles and neo-Gothic features. A self-guided architecture tour can begin by the great bear statue in the central Puerta del Sol. Wander by the fanciful Royal Palace before absorbing the natural beauty of Retiro Park, then visit one of the city’s many museums. You could happily cap off each day by nibbling on forkfuls of paella while sipping Spanish rioja.

The museums of Lisbon celebrate the rich history and culture of this Portuguese capital city. The Maritime Museum is perfect for kids (and grown-ups!) who adore all things nautical, while the Casa-Museu Dr. Anastácio Gonçalves is a hidden gem of colorful artwork. To fully appreciate the city’s dramatic stone architecture you can take a guided walking tour, or customize your own tour, making sure to visit the Padrao dos Descobrimentos, the Mosteiro dos Jeronimos, and the UNESCO World Heritage site the Torre de Belem.

Over the centuries, many cultures have added their mark to this prized piece of land. Today, you can experience those influences firsthand by exploring Istanbul’s mahalles (neighborhoods). From the holy sites of Sultanahmet and the 19th-century European elegance of Beyoğlu to the high fashion of Nişantaşı, the vibrant café society of Kadıköy and the football-loving streets of Beşiktaş, it’s easy to see why travelers say that Istanbul isn’t just one city, but many cities within one.

On the Turkish Riviera, traditional fishing villages such as Üçagiz nestle alongside the modern resort destinations of Marmaris and Antalya. Unspoiled yellow sand beaches and pine forests line this history-rich coast whose illustrious former residents include St. Paul. Buses make easy connections between the coves, castles and cities beside the turquoise waters of what the Turks call the “White Sea.” Don’t miss the awe-inspiring eternal fires of Chimaera at Olympos – most impressive at night.

Conquering New York in one visit is impossible. Instead, hit the must-sees – the Empire State Building, the Statue of Liberty, Central Park, the Metropolitan Museum of Art – and then explore off the beaten path with visits to The Cloisters or one of the city’s libraries. Indulge in the bohemian shops of the West Village or the fine dining of the Upper West Side. The bustling marketplace inside of Grand Central Station gives you a literal taste of the best the city has to offer.

At the shore in Miami Beach, visitors can swim, surf and jet ski in the warm and crystal-clear Atlantic waters. You can also nap on the white sands, work on a tan or simply watch the beautiful people, especially at South Beach, a favorite of models and celebrities.

New Orleans is full of life—but with a laid-back energy that sets it apart from other cities. You’ll wanna soak it all in: impromptu jazz performances up and down Frenchmen Street, the ding of the St. Charles Streetcar, moss-draped trees in the famous Garden District…even its gothic, above-ground cemeteries. (The city’s said to be one of the most haunted in America.) For some, NOLA will always be all about Bourbon Street, but for travelers looking to take it slow, the city’s distinct blend of cultures—including Creole and Cajun—means there’s tons to see, explore, and yes, eat.
