The Rio Negro–Rio San Sun mangroves form a labyrinth of tidal channels and dense mangrove forest on Tortuguero's northern edge. Boat tours navigate these narrow waterways, passing under arching roots where caimans, river otters, and green iguanas rest. The mangroves are a nursery for fish and crustaceans, and birdlife includes herons, kingfishers, and the striking green-and-rufous kingfisher. The quiet, shaded environment contrasts with the open canals of the national park, offering a more intimate wildlife experience. Tours typically depart from Tortuguero village.
