The Rio do Bispo is a watercourse located in the municipality of Urubici, within the state of Santa Catarina, Brazil. It flows through a region that is part of the Atlantic Forest biome and lies within the vicinity of the Parque Nacional de São Joaquim. The river's character is shaped by its passage through diverse landscapes, including open fields and areas of native araucaria forest, as well as sections with eucalyptus plantations. A primary access point for reaching the river is via the SC-370 highway. From there, a turn onto the Rio do Bispo road leads approximately 2 kilometers to the Sítio Terras do Sul property. Another common approach is to travel 18 kilometers on the SC-370 from the ICMBio administrative headquarters in Urubici, heading towards the Serra do Corvo Branco, and then turning right onto an access road. The area is known for its scenic natural features, including waterfalls such as the Cachoeira Arroio Boca da Serra, which are accessible via trails that follow the river. The region's aesthetic is defined by the mountainous terrain of the Serra Geral and the distinctive, ancient araucaria trees. As the river is situated within a national park, paddlers must be aware of and comply with all regulations set by ICMBio, the federal environmental agency responsible for managing the park.
