Rio Formoso flows near the town of Bonito in Mato Grosso do Sul, and is widely recognized for its exceptional water clarity and vibrant green color. The river's transparency allows paddlers and swimmers to observe aquatic life directly from the surface, making it one of the more visually distinctive waterways in the region.

The Parque Ecológico Rio Formoso, located approximately 7 kilometers from central Bonito along a fully paved highway (Rodovia Bonito Guia Lopes, Km 7), serves as the primary access point for paddling activities on the river. The park is open Monday through Sunday, 8:00 AM to 5:00 PM, and is closed on Thursdays. Kayaking and stand-up paddleboarding are both offered within the park, primarily on the Lagoa Formosa section. The park also features a rapids descent option for those seeking moving water. Life vests are included with activities, and wetsuits are often provided for flotation tours, which reflects the river's notably cool water temperature.

Wildlife in and around the river includes a variety of fish species visible through the clear water, and anacondas inhabit the area. The surrounding vegetation is well-preserved, consistent with the broader ecological character of the Bonito region.

The park infrastructure includes a restaurant, restrooms, changing rooms, and rest areas. Parking is available on-site, and the proximity to Bonito makes the park accessible by bicycle as well as by car or shared transport. All transportation options operating in Bonito are accredited with the park.

Advance booking is strongly recommended, particularly for popular activity slots. Ticket prices vary by activity package, with admission starting around $40 USD. Some packages include equipment; food and drinks, as well as hotel transfers, are generally not included. Given the managed nature of the site, paddling here takes place within a structured, guided framework rather than as an independent open-water excursion. Visitors should bring sun protection and adequate water, especially if arriving by bicycle.
