The Rio Potengi flows through the state of Rio Grande do Norte, emptying into the Atlantic Ocean at Natal, the state capital. The river is approximately 110 miles in length, with its lower estuary section being the primary area of interest for paddlers. The name translates roughly to "Rio Grande" in the local Tupi language, and the river has long been central to the history and identity of Natal.

The estuarine stretch near Natal is where most paddling activity takes place. This section passes landmarks including the Estuário Iate Clube, the Dique da Base Naval, and the area near the Ponte de Igapó. The iconic Newton Navarro bridge spans the river and forms a recognizable backdrop. The port of Ribeira, where cargo vessels call, is also located along this lower reach, so paddlers should be aware of commercial vessel traffic in the estuary.

Guided kayak tours operate on the river and are rated as easy, making the lower Potengi accessible to beginners and recreational paddlers. Sunset paddles are a popular format, typically running in the late afternoon from around 15:30 to 18:00, taking advantage of Natal's roughly 300 days of sunshine per year. The city's tropical climate means warm conditions year-round, consistent with the region's northeast Brazilian location.

Flow monitoring stations are present at several points along the river, including at Barcelona, Telha, Igreja Nova, and near the estuary, indicating that water levels are tracked along much of its length. The river's lower section is tidal and estuarine in character. Paddlers should account for the presence of commercial port activity and naval facilities in the estuary when planning routes.
