Mayan ruins tower over the sea in Tulum. The formerly walled city was one of the last to be built by the Mayans, and its archaeological sites are incredibly well preserved. Take a break from the beach to visit El Castillo, the Temple of the Frescoes, and the Temple of the Descending God. Explore an underground river under a canopy of stalactites in the sacred caverns of LabnaHa Eco Park, or dive into Cenote Dos Ojos to snorkel inside of caves in the middle of a forest.

Santo Domingo, the capital of the Dominican Republic and a UNESCO world heritage site, is the oldest continuously inhabited European settlement in the Americas and one of the most populous cities in the Caribbean. The city is a mix of old world charm and modern Latin flair. Its medieval palaces and fortresses mix with nightlife and shopping to rival any modern city in the world. You'll find pristine beaches and hidden gems like a salsa/merengue club set inside a huge underground cave.

The Grand Canyon is on almost every traveler's bucket list. Indeed, Theodore Roosevelt called it "the one great sight which every American should see." The Bright Angel and South Kaibab Trails offer stunning views, but if hiking's not your cup of tea, rent a bicycle or take a scenic drive through the park.

A mixture of urban chic and outdoor adventures, Spokane has something for everyone. Taste food by James-Beard-nominated chefs at Sante or The Wandering Table. Listen to live music at The Bartlett or the symphony at the iconic Martin Woldson Theater at The Fox. Glide over the breathtaking Spokane Falls, situated right downtown, in the SkyRide, rated as one of the world’s best gondolas. Kids can feed the Garbage-Eating Goat or slide down the giant Radio Flyer Red Wagon in Riverfront Park.

Tribal Terenife still shows influence from the aboriginal Gaunches people. Visitors clamber to conquer Mount Teide (Spain’s tallest peak) and to stretch out on the sands of Los Gigantes. Squawk hello to the playful parrots of Loro Park, or brave the petrifying drive to beautiful Masca Valley. For a true taste of Terenife, sample fresh farmhouse cheese and local bananas. A piece of delicate calado canario lace makes a special souvenir.
