General Description

The Rio Volcan is so named because it is serves as the primary drainage of the southern and eastern slopes of the still active San Jose Volcano. A trip up the Volcan River Valley is a little like touring a moonscape. Due to the high altitude there is little vegetation growing along the river or slopes. What does grow is scrubby or trees in isolated patches. At the top of the valley are two thermal spas, Banos Morales and Banos Colina as well as Monumento Natural El Morado nestled in a side canyon to the north.

As a result of the defoliated wide-open terrain the Volcan River is fairly accessible from the valley road. The Rio Volcan has two primary kayak runs above and below the small settlement of El Volcan. The upper section is a class V+, high volume steep creek described as “tight, and pushy with blind drops” and mandatory portages. The section below El Volcan is a class IV/V run that is more reasonable, provided the water levels are right.

Hazards

The Upper Section of the Volcan River has a number of mandatory portages and pushy class V+ drops. Pass on this run unless you are an expert kayaker. Furthermore the Rio Volcan is a rarely run river that has a frequently changing riverbed due to seasonal flooding and landslides. Exercise caution on all sections.

River Flows / Gauge Information / Season

The overall flows on the Rio Volcan mirror those of the Maipo River which is commercially rafted throughout the year. The raft companies consider the highwater season to be from September through April. The period of “high flood” is generally December and January in which all rivers in this region can reach epic proportions. Flows between 500 - 2000 cfs (15 - 57 cm/s) can be considered normal for the Rio Volcan. Higher water makes the runs more difficult. At lower flows, noticable changes can can occur in volume due to the daily warming of the glaciers and snowpack. Expect lower volumes in the morning and increasing steadily throughout the day if the sun is out.

Directions

From Santiago de Chile head southeast, up the Rio Maipo Valley to the village of San Jose del Maipo. The drive will take you about an hour. The Rio Maipo - Rio Yeso confluence is another 25 kilometers in the direction of San Gabriel. Continue on, about 3 kilometers, until you come to the Rio Volcan - Rio Maipo confluence. Another 16 kilometers on this road will take you to the Termas Banos Morales.

Places to Stay / Campgrounds

There are numerous places to stay in the Rio Maipo River Valley, but the most famous is the Cascada de las Animas Eco-Resort. They have tenting or luxury cabin options depending on your personal preference. Cascada de las Animas is located in the town of San Alfonso, north of the Rio Maipo River, on the right side of the main valley road going from Santiago.
