Already a popular day trip, this jade-colored waterway rocketed to fame as the site of Calypso's house in Pirates of the Caribbean. Hire a guide and colorful rowboat—most seat up to eight passengers—for this one-mile excursion upstream. Watch for crayfish and young barracudas in the brackish river, which is lined by mangroves with mighty buttress roots. Don't miss the fruit drinks and Dynamite rum punch at the Bush Bar, the trip's turnaround point.
Site pass required: EC$13 ($US5) per day or EC$32 (US$12) per week. (767) 266-3817; email@example.com; dominica.dm/index.php/national-parks
