Warm, welcoming and generally uncrowded, Dominica is a great destination for children, unlike some of its glitzier, hard-partying Caribbean counterparts. "Go play outside" is the order of the day here. Head to the west coast beaches for safer, sheltered swimming (Purple Turtle and Douglas Bay tend to be family favorites). Stretch short legs on hikes like the Syndicate Nature Trail and Cabrits National Park paths, then swim below a jungle waterfall at the Emerald Pool. And don't miss the chance to see sperm whales and 13 other marine mammal species!
