Rio Volcán (Lower)
The lower Volcán is a much easier version of the upper run. Although this turbid river maintains its steep, continuous gradient, the rapids lack the intensity of those upstream. The best drops, located near the take-out, never get more difficult than class IV.
Refer to the directions of the upper Maipo to get in the area. Continue upstream 3 km from the Puente El Yeso through the town of Romeral. Turn north, and put in at village of El Volcán 1380 meters. Take out 4.5 km downstream at Puente El Volcán 1255 meters..
This 4.5 KM stretch of river has average drop of 28 m/km or 147 feet per mile and can be run year round with optimal flows 500-900 CFS making it class 4.
