The soundtrack of tranquil Boa Vista is the sweet tweets of exotic birds. Maybe they’re chattering with loggerhead turtles or with the humpback whales that are known to splash around Boa Vista’s shallow waters. Work up a sweat and hike to the wreck of the Santa Maria, or explore the Duque de Braganca Fort, built to protect the Ilheu de Sal Rei from pirates. The windswept red and tan sand dunes of Deserto de Viana are awe-inspiring.

From quaint town shops and quiet beaches, to honky tonk arcades and carousels, the York area is guaranteed to entertain the whole family. Old York, run by the local historical society, contains nine different restored buildings, including "The Old Gaol," the oldest jail in America. The beautiful coastline provides cliff walks with views of an authentic Maine lighthouse. Head to nearby York Beach and visit York's Wild Kingdom, an amusement park and zoo that is home to Rewa, a White Bengal tiger.

The Outer Banks of North Carolina is a 100-mile stretch of barrier islands dotted with pristine beaches, quaint towns and historic sites. If you love swimming, kayaking, or surfing, be sure to visit the Cape Hatteras National Seashore. To really experience local culture, explore each coastal village and sample as much food as you can along the way. (Pro tip: Try the catch of the day.) If you’re looking for a history lesson, check out Roanoke Island or the Wright Brothers National Memorial. And of course, no day is complete without watching the sunset from Jockey’s Ridge.

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 Zanzibar Archipelago, located in the Indian Ocean 15 miles off the coast of Tanzania, is a breathtaking spot to escape from the world. You’ll enjoy clear, turquoise-blue water; shallow sandbars perfect for wading; and many small, nearly deserted islands virtually unvisited by tourists. Explore the World Heritage Site of Stone Town, Zanzibar City’s old quarter. Or just go beach to beach between tiny fishing villages—each one's better than the next.
