Itaimbezinho CanyonApprox. Time: 8 hours
Activity Level: Moderate to Strenuous

The biggest canyon in Brazil is near the border of the southern states of Santa Catarina and Rio Grande do Sul, inside the Parque Nacional dos Aparados da Serra. It is nearly six miles long and a mile deep, the Itaimbezinho is spectacularly beautiful but can be deadly!

The Rio do Boi flows through the canyon and countless waterfalls plunge down into the river. Hiking is best done in the dry season (July–October), but be careful of the weather due to the quick flash floods. During the wet season the hiking is still possible, but you may want to stick to the Cotovelo Trail, which follows along the canyon's edge. It, too, is beautiful and spectacular, with the only real danger being a trip too close to the edge.
