The Rio Piratini, also referred to as the Rio Piratinim, is a river flowing through the southern Brazilian state of Rio Grande do Sul. It has a total length of approximately 120 kilometers (75 miles). For paddlers planning a trip, resources such as PaddleWays and onWater Fish provide access to planning tools, maps, and information on access points for putting in and taking out. These platforms can help identify boat ramps and other facilities necessary for a day on the water. The river is noted for fishing activity, which suggests paddlers may share the waterway with anglers. Paddlers are advised to consult detailed local resources for access points, water conditions, and any private or public land boundaries before embarking.
