Divers and snorkelers will be dazzled by the wrecks of Xcaret and the Puerto Morelos reef.

Akumal means "Place of the Turtle" in the Mayan language, and if you snorkel here, you just might see one swimming alongside you. (Don’t touch it, though. That’s prohibited by law.) You’ll definitely see coral and beautiful fish in the clear, sparkling waters. This tourist-friendly little town is about an hour south of Cancun—but it seems light-years away.

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.

Ford, 38th U.S. President, where interactive exhibits take you to the White House and the 1976 Republican National Convention.

The city is dominated by an elaborate 10-building complex that includes the State Capitol; the New York State Museum, with life-like dioramas such as American Indian life and an Adirondack logging operation; and the oval-shaped Empire State Performing Arts Center, nicknamed "The Egg." History buffs will enjoy the colonial homes, historic churches and museums, and can tour 18th-century mansions, like the Schuyler, a superb example of pre-Revolutionary War architecture. Whether nature or history is your passion, you'll find an abundance of both in this upstate New York gem.

Welcome to the Nature Island. Remote, affordable and, as yet, unspoiled, Dominica deserves more than a day's visit from your cruise ship.

The Pioneer Museum offers a glimpse of what life was like for the early settlers of the region and includes a 1929 Baldwin locomotive in its collection.

The town that gave the country (and port wine) its very name, Porto is Portugal’s second-largest metropolis after Lisbon. Sometimes called Oporto, it's an age-old city that has one foot firmly in the industrial present.

The 14th-century São Francisco church is a main attraction, as are the local port wine cellars, mostly located across the river at Vila Nova de Gaia.
