The Rio Mundaú in Ceará, Brazil is a coastal river whose lower reaches flow through a mangrove swamp before reaching the Atlantic Ocean at Praia de Mundaú. A significant feature for paddlers is the Barragem do Açude Mundaú, a dammed reservoir, which offers a distinct flatwater paddling environment separate from the river's tidal estuary. Information on specific put-in and take-out points for the river itself is limited, though one known access point is at Praia de Mundaú, where catamaran tours begin for excursions into the mangrove ecosystem. The river's mangrove swamp is noted as a biome of great ecological significance, suggesting a paddling experience characterized by winding channels through dense, protected coastal wetlands. While no direct safety hazards or water quality issues are detailed, paddlers should be aware that mangrove environments can present navigation challenges and tidal influences. The area is served by commercial tour operators offering guided catamaran rides, indicating that recreational use of the waterway is established. There is no information available on seasonal water temperature patterns, specific regulations for private paddling, recommended routes, facilities, or the river's historical significance.
