Regional overview
This entry covers the Rio Grande do Sul side of the southern Brazilian canyon plateau, chiefly Cambara do Sul, Parque Nacional da Serra Geral, and Sao Jose dos Ausentes/Monte Negro. It avoids duplicating the Itaimbezinho walks already assigned to the Aparados da Serra entry except where region-level context is needed.
Rio Grande do Sul canyon country is the basalt escarpment zone where the high, cool campos of Cambara do Sul and Sao Jose dos Ausentes drop into forested gorges draining toward Santa Catarina. Hiking alternates between high-rim viewpoints, waterfall/ravine routes, and short state-high-point walks.
The key public landscapes are Cânion Fortaleza, Cascata do Tigre Preto, Pedra do Segredo, Malacara/Churriado and Pico do Monte Negro. Much of the area sits within or beside Parque Nacional da Serra Geral and the UNESCO-recognised Caminhos dos Cânions do Sul Geopark. Fog, wind, storms and cliff-edge exposure are the major hazards.
Access rules can change under park concession and private-property arrangements. Several routes require local guidance or at least current local confirmation. Official GPX downloads were not found.
Selection rationale
The five hikes represent the essential Rio Grande do Sul canyon palette: Fortaleza’s grand rim, Tigre Preto/Pedra do Segredo, a longer Fortaleza loop variant, Malacara/Churriado, and the state high point at Monte Negro.
