Emerald Pool

"Stroll 15 minutes through a lush rainforest to this gorgeous 40-foot waterfall grotto, located deep within the World Heritage site of Morne Trois Pitons National Park. Railings and a broad, well-maintained trail make the trip accessible even to non-hikers, though the tree-fringed pool—which is open to swimmers—gets unpleasantly packed when cruise ships pull into port. Serious photographers should haul along tripods and cable or remote shutter releases to capture the low-light, but oh-so-lovely scenery, which has become one of Dominica’s top attractions."
