The Rio Cauipe in Ceará, Brazil, flows into the Atlantic Ocean near the coastal communities of Cumbuco and Caucaia. The river's mouth forms the Barra do Cauipe, a lagoon area that is a significant hub for wind-based water sports, particularly kitesurfing and wing foiling. This indicates that the area can experience consistent winds, which paddlers should consider when planning a trip. The lagoon at the river's mouth is described as having hot water and being a scenic location. A notable access point for the area is Praia do Cambuco, which features a trailhead. The water quality in the lagoon has been noted by visitors to sometimes contain floating debris, suggesting paddlers should be observant of general cleanliness. The overall character of the paddling experience appears to be coastal and lagoon-based, with the river meeting the sea in a busy, recreational area popular with tourists and sports enthusiasts. The region offers services for water sports, including equipment rental and lessons, though these are geared more towards kitesurfing than passive paddling. The best time for calm-water paddling would likely coincide with non-windy days, as one visitor reported having more fun on the lagoon during such conditions than when kitesurfing. The area is part of a buggy tour route, indicating it is a recognized stop for tourists exploring the coastal dunes and beaches of Ceará.
