Just north of Cancun, this seaside resort community is a far cry from the spring-break crowd. Bordered on one side by the Mexican Caribbean and the other by a wetlands wildlife preserve, the vibe in Playa Mujeres is one of laid-back luxury in a natural, untouched landscape. Unlike many other such tranquil places, Playa Mujeres is not a pain to get to. It's an easy ride from Cancun airport.

Once a sleepy fishing village, Placencia has emerged as an increasingly popular eco-destination on the Caribbean. For those who enjoy outdoor adventure, the Stann Creek region offers a host of activities: hiking through mountainous rain forests, kayaking, deep sea fishing, diving and exploring Mayan ruins. The peninsula boasts 16 miles of tranquil beaches, with a lagoon to the west and the Caribbean to the east and lots of peace and quiet in the middle. Tour guides and dive centers offer a variety of excursions, with boat rides to the outer cayes an ongoing favorite. Also popular are guided land tours to Mayan Ruins or trekking the jungle trails of Cockscomb Basin Wildlife Sanctuary, where the first Jaguar Reserve in the world was established.

One of the most historic cities in America, Philadelphia is an ideal place to spend a weekend - preferably a long one. Be sure to see the Liberty Bell and Independence Hall, where the Constitution and Declaration of Independence were signed. Both are part of Independence National Historic Park. Philadelphia also boasts some outstanding art museums, including the Rodin Museum. The Franklin Institute Science Museum is one of many area attractions honoring the life and work of Benjamin Franklin, the city's most famous ambassador. After digesting all of that history, be sure you save room for a classic Philly cheese steak sandwich.

Visit Provincetown and have a blast enjoying some of Cape Cod’s best beaches (Race Point Beach and Herring Cove Beach are favorites of TripAdvisor travelers). Plenty of cool boutiques, restaurants and art galleries give this town a fun and funky vibe. It’s an exceptionally LGBT-friendly destination as well. One tip: if it’s high season, take the ferry or a quick flight from Boston (unless you enjoy spending hours sitting in traffic).

It's true: you can surf in Canada. And Tofino, on the west coast of Vancouver Island, is where you'll find exceptional surfing, Canadian-style. Busiest in summer, Tofino also fills up in winter when storm watchers descend upon this tiny town.

Costa Teguise in the Canary Islands doesn’t have a long history behind it—the resort area was developed as a tourist area in the 1980s. The sandy beaches are the town’s main attraction, but for a change of pace, visit the Fundacion Cesar Manrique, where you can see Manrique’s artwork and learn about this world-renowned local artist.

Brittany's dramatic 750-mile coastline traces a rugged hem against the chilly Atlantic. Attractions such as St-Malo's 1689 Fort National, the prehistoric ruins and striking beauty of Gavrinish Island and Brest's Oceanopolis aquarium cling to the rocky shoreline of France's most northwestern province. Nantes, Rennes and Brest are the largest cities. Rennes is just two hours from Paris by TGV. Breton and Gallo, the ancient languages of this Celtic province, are still spoken in pockets throughout the area.
