The Rio Piraquê-Mirim is located within the municipality of Aracruz, in the state of Espírito Santo, Brazil. It flows through the Reserva de Desenvolvimento Sustentável Municipal Piraquê-Açu e Piraquê-Mirim, a protected area of 2,080 hectares established in 1986. The reserve's primary purpose is the protection of mangrove ecosystems and their associated environments, flora, and fauna. Visitation to this reserve is permitted free of charge, which includes access for paddling activities. The river's character is defined by its estuary environment, where freshwater from the inland flow meets the coastal mangrove system. This creates a paddling experience focused on natural observation within a preserved and ecologically significant landscape. The area is noted for its extensive mangroves, which are protected in their natural state, offering paddlers a chance to navigate through these unique coastal forests. The reserve encompasses the entire associated environments of the mangrove, suggesting a network of channels and waterways typical of such ecosystems. As a protected sustainable development reserve, the primary regulations for paddlers will involve respecting the natural habitat, with an emphasis on preservation.
