U.S. citizens still need to jump through a few hoops to visit Cuba, but as visitors from around the world know, this island offers some amazing opportunities for cultural exchange. Havana is a mix of old-world architecture and of-the-moment culture. Head out of the capital city to the small town of Trinidad to see more Spanish colonial architecture. It’s a UNESCO World Heritage Site and a fantastic home base for a visit to the Valley of the Sugar Mills, a pocket of land that formerly served as the centre of Cuba’s sugar industry.

Travelers come to this small island north of mainland Cuba to bask in the sun, swim in sparkling blue water, and be pampered at an all-inclusive resort. To explore Cuban culture, you’ll need to go farther afield (this is a planned resort development; employees are bused in), but if you’re simply looking for a stress-free tropical break, Cayo Santa Maria might be perfect for you.

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.

This beautiful fishing village is a Nicaraguan gem, a magnet for surfers and sunbathers. At night, the beach still pulses with activity, thanks to a few popular beachfront bars and nightclubs. Surf clubs abound—catch a wave with an expert instructor if you’re a hang-ten rookie, trying to hang with the surfer big boys.

There's more than one way to enjoy the spa experience in St. Lucia. One is to book a treatment at any of the luxury spas or resorts on the island. The other is to visit Sulphur Springs, inside the bowl of an extinct volcano, where you're welcome to try a volcanic mud bath or the 31°C/88°F Roman bath.

Here’s your day in Calistoga: Yoga. Massage. Spa lunch. Hike. Wine-tasting. Facial. Mud bath. Gourmet dinner (with more wine). Dip in a mineral pool. Does it get more relaxing than a spa town built around natural springs in the middle of wine country? We don't think so.

With the dramatic backdrop of 12,200-foot Mount Teide towering behind the resort, Adeje makes an unforgettable holiday destination. Adeje is less than two miles from the boisterous nightlife of Playa de las Americas, allowing visitors to choose whether to take it easy or to party. Bake in the sun on black volcanic sands before cooling down at a water park, such as popular Siam Park, or out windsurfing. Barranco del Infierno, Hell's Gorge, is a lush oasis, perfect for hiking.

Visitors who come to Ibiza’s energetic capital for its nightlife are treated to more than just thumping ultraclubs and celebrity sightings. By day, the harbour town is a sun-drenched sampler of Spanish-island style, with waterfront cafes, urban beaches, trendy boutiques, and even a UNESCO-listed fortress.
