The Rio Manoel Alves flows through the municipality of Rio da Conceição in the state of Tocantins, Brazil. A notable activity on this river is the Buoy Cross Adventure, also known as Boia Cross, which is a family-friendly adventure activity offering direct contact with the water and nature. The river's character is oriented towards adventure tourism, suggesting a natural setting suitable for water-based recreation. The overall experience appears to be informal and focused on active engagement with the river environment rather than on structured, long-distance paddling trips. The existence of a commercial adventure operation implies some level of local infrastructure for visitors.
