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?

Everyone who visits Paris for the first time probably has the same punchlist of major attractions to hit: The Louvre, Notre Dame, The Eiffel Tower, etc. Just make sure you leave some time to wander the city’s grand boulevards and eat in as many cafes, bistros and brasseries as possible. And don’t forget the shopping—whether your tastes run to Louis Vuitton or Les Puces (the flea market), you can find it here.

Set on Spain's Costa del Azahar, the fortified city of Peniscola features sprawling Mediterranean beaches and an old town surrounded by medieval castle walls. Cobbled streets wind past museums, restaurants, and white-washed houses, while a nearby nature reserve boasts miles of pristine countryside.

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.

This pleasant, walkable town right at the elbow of Cape Cod is a classic New England vacation spot. Bringing kids? Check out calm beaches like Cockle Cove Beach and Harding’s Beach. If you’re looking for stunning scenery, however, try Chatham Lighthouse Beach. Its tides can be strong (heed the posted warnings), but it’s one of the most beautiful beaches on the Cape.

With its collection of historic homes, museums and battlefields, Frederick, Maryland, is a must-see destination for any history enthusiast. The sites of two bloody Civil War battles are preserved at Monocacy National Park and South Mountain State Park. Within the city, visit the National Museum of Civil War Medicine and learn how soldiers wounded in those battles were treated, or visit the house of Barbara Fritchie and picture her hanging the Stars & Stripes in defiance of the Confederate Army.
