Quite possibly the most visited nature attraction on the island, this emerald-green pool fed by a 50-foot waterfall is an easy trip to make. To reach this spot in the vast Morne Trois Pitons National Park, you follow a trail that starts at the side of the road near the reception center (it's an easy 20-minute walk). Along the way, there are lookout points with views of the windward (Atlantic) coast and the forested interior. If you don't want a crowd, check whether there are cruise ships in port before going out, as this spot is popular with cruise-ship tour groups.
