A:Sleepy, barely-discovered Dominica is kind of like Costa Rica, just on its own island—verdant, hilly, and filled with tropical beauty. Domica attracts an outdoorsy set who prefer zip-lining and hiking through volcano-carved jungles over sunbathing. And the finest of the island’s small selection of eco-resorts is Jungle Bay. Its hardwood-framed cottages, etched into the steep hillside on stilts—some that require a 200-step climb from the main path—overlook the water and offer seclusion within the jungle. Rates start at $283 a night.
