The Rio Cocó flows through the heart of Fortaleza, Ceará, passing through the Parque Estadual do Cocó — one of the largest urban parks in South America. The park extends from the border zone between Fortaleza and Maracanaú to the river's mouth at Sabiaguaba, encompassing roughly 1,155 to 1,575 hectares of mangroves, dunes, and native Atlantic Forest. The river corridor within the park offers a notable contrast to the surrounding urban environment, with dense riparian vegetation lining much of the route.

Organized ecological boat tours on the Rio Cocó operate within the park and represent the primary paddling-style experience available to visitors. These tours typically run on weekends and holidays from morning until midday, and may require a separate fee or advance booking. Paddlers interested in these tours should confirm current schedules and booking requirements through the park's official channels before visiting, as arrangements are subject to change.

The main access point for the park is along Avenida Padre Antônio Tomás in the Cocó neighborhood of Fortaleza. The park can also be reached by public transit, including several bus lines and the VLT light rail (Papicu station). Park hours run from 5:30 to 22:00, though walking trails close earlier at 17:45.

Wildlife along the river is diverse. Paddlers can expect to encounter species including Cocoi Heron, Rufescent Tiger-Heron, Wattled Jacana, Purple Gallinule, various kingfishers, and multiple woodpecker species. The mangrove sections support molluscs, crustaceans, fish, and reptiles, including some species of conservation concern. Birdwatching is productive year-round.
