The Mutum River, also known as Ribeirão Mutum, is a watercourse in the state of Mato Grosso, Brazil, flowing through the Pantanal region. It is accessible near the municipality of Barão de Melgaço, where a bridge spans the river. A key access point for paddlers is the Pousada do Rio Mutum, a lodge situated directly on the river's banks. From this location, paddlers can explore connected waterways, including the lakes of Sia Mariana and the Baía de Chacoraré. The river's character is defined by its Pantanal setting, offering a flatwater paddling experience through a vast, seasonally flooded wetland. This environment provides significant opportunities for wildlife observation, with the surrounding bays and lakes serving as rich habitats. The area's aesthetic is dominated by the open landscapes and aquatic systems typical of the Pantanal. The presence of a dedicated riverside lodge indicates the area is established for nature-based tourism and recreational activities like boating and paddling.
