Tiny Grenada is nicknamed "the spice island," and a trip here is anything but bland for adventure travelers. A six-hour hike from Grand Etang to Concord slices through the rainforest beneath a canopy of birds, monkeys, and exotic vegetation. At the end, travelers are rewarded with a swim at Concord Waterfalls. Can't get enough hiking? Then return to Grand Etang and take a five-hour trek to Fedons Camp, tucked 2,500 feet above sea level in a misty rainforest. Atop Mount Qua Qua, adventurers follow the route from which Grenada's first revolutionaries began their overthrow.
