Dominica

Rumor has it, once you've mastered driving on Dominica, you can drive anywhere in the world.

It's easy to see why. It is, literally, a jungle. Its roads, most of which are no wider than a Chicago alley, crawl over mountains and cling to cliffs tumbling down to the Caribbean Sea. All of their turns are shaped like hairpins, and all of their curves are as blind as the nightfall here, where there are no streetlights or stoplights—only stars. And, just to make things interesting for the 66 percent of the licensed driving world who are accustomed to keeping right, Dominica's former British Commonwealth status means that here, one hugs the curves to the left.

But driving on Dominica would be missing the point. This island is meant to be explored on foot, ideally while wearing a pair of Teva sandals. It's crawling with natural hiking trails adorned by 1,200 species of plants and flowers, some of which recoil when touched, like sea anemones. There are spectacular waterfalls and hot springs, including the huge Boiling Lake in the center, and the island is surrounded by waters clear enough for snorkeling, deep enough for diving and just choppy enough to make kayaking interesting. And because it's not easy to get here (travel time runs about 17 hours with two connections), it remains—and here's the tour operator's selling point—"one of the most unspoilt islands in the Caribbean."

Pronounced "Dom-in-EEK-a," not to be confused with the Dominican Republic (though it often is), this English-speaking volcanic island is home to about 71,000 people, including 3,000 native Caribs, who reside in a dedicated Carib Territory on the island's northeast side—similar to the Native American reservations in the States.
