Half Day tour: This circuit departs from San Lorenzo, a village located on the foothills of the Andes, which are known as Precordillera or Cordillera. Here, you will find one of the most extraordinary ecosystems of northwestern Argentina, called yungas (a jungle that grows in the mountains). This circuit includes many trails crossed by streams and rivers.

Full Day Tour: This option begins in the village of Campo Quijano, known as 'The Andes Portal,' in the area of Quebrada del Toro (Bull's Gorge). The circuit runs through the first part of the gorge, an area with deep canyons and lush vegetation. You will cross a 130-foot-high (40-meter) bridge in order to get to a beautiful waterfall called Chorro Azul, a fantastic resting spot to relax and regain energy before continuing on to the second part of the circuit — a 4-mile (6-km) downhill trail.
