Ibiza: Old Spanish for "party 'til you drop." Perhaps not literally, but this is definitely one of Europe's favourite nightlife playgrounds. Ibiza boasts more than 100 miles of coastline with some 50 beaches, plus plenty of restaurants, bars, and water sports—and clubs, of course. Fit in a little culture and visit Ibiza's UNESCO-designated old town.

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.

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.

Travel into Spain's Moorish and Christian history with every step you take in compact, walkable Granada. The famous Alhambra fortress is a required visit, as are the Alcaiceria (marketplace), the Cathedral and too many architectural sites to name. Wander through Granada's fascinating Moorish old quarter, the labyrinthine Albaicin; then plan to head out again by night, because the nightlife here is particularly lively.

Overlooking the azure waters of the Adriatic Sea, petite Polignano a Mare is home to some of Puglia’s loveliest beaches. Ringed by dramatic cliffs, the Lama Monachile Beach—also known as Cala Porte—is one of the most coveted, and most photographed, in the region.

From Shoreditch’s swaggering style to Camden’s punky vibe and chic Portobello Road, London is many worlds in one. The city’s energy means that no two days are the same. Explore royal or historic sites, tick off landmarks from your bucket list, eat and drink in exclusive Michelin-starred restaurants, enjoy a pint in a traditional pub, or get lost down winding cobbled streets and see what you stumble across – when it comes to London, the possibilities are endless.

The second largest city in Russia, St. Petersburg is the country’s cultural heart. View splendid architectural gems like the Winter Palace and the Kazan Cathedral, and give yourself plenty of time to browse the world-renowned art collection of the Hermitage. Sprawling across the Neva River delta, St. Petersburg offers enough art, nightlife, fine dining and cultural destinations for many repeat visits.

Camden, Maine is proud to call itself the "Jewel of the Coast." A beautiful seaport town with a harbor full of sail boats, Camden has been used as the setting for so many movies, from Carousel to Peyton Place, that it is what many people think of when they think of New England. With a series of annual festivals running all year round, including the US Toboggan Championships, the Summer HarborArts Juried Arts & Craft Show and Windjammer Weekend, there is always something to do in Camden.

The first time you go to New York, go ahead and be a sight-seer—everyone should visit the Statue of Liberty, the Met, Times Square, etc. But on a return trip, pick a neighbourhood and go deep. You’ll find hole-in-the-wall bars, great delis, quirky shops… exploring the non-touristy side of New York is an incredibly rewarding experience for a traveller.
