Quick Facts

General Description

The Rio Ancoa is tributary of the Achibueno River, in the Linares Province, of the Maule Region of Chile. The runnable section of the Ancoa River is about eleven kilometers long and is an action packed whitewater experience. The Rio Ancoa receives its water through a tunnel from Rio Melado that seems to deliver a steady 800-1000 cfs (~36cms) of water all summer long, intended for irrigation of the agricultural fields in the Ancoa River Valley. The most memorable thing about any kayak trip to the Rio Ancoa is usually the condition of the road to get to the put-in, described by some as, 'the most terrible road in all Chile'.

Hazards

Undercut rocks and sieves will probably require you to portage at least twice on this run. This is not a river to take lightly and is worthy of its class IV/V reputation, especially in the upper sections. Should a swim occur it is easy to lose a paddle or a kayak. You can make it easier by putting in and taking out more selectively.

River Flows / Gauge Information / Season

The typical kayak season for the Rio Ancoa is November - February. The river is fed from a diversion tunnel from the Rio Melado and typically runs all summer long between 800-1000cfs (~36cms). Catch higher flows, if you dare, earlier in the season.

Put-Ins and Take-Outs

  • Put-in: The most popular put-in is at the Tunel El Melado Outlet in Hornillo.
  • Take-out: Take-out either at the diversion dam or continue on down to the second bridge.

Directions

From the city of Linares head out toward the village of Llepo but take the left fork of the road that follows the Rio Ancoa instead of heading into Llepo itself. Follow the Ancoa River through Capamento Ancoa until you get to the put-in at Hornillos. Here you will find the outlet of the tunnel that runs through the Andes to the Rio Melado. The total trip to Hornillos is about 50 kilometers from Linares, but they will be some of the most difficult driving you will ever encounter in Chile.

Places to Stay / Campgrounds

It is possible to camp riverside almost anywhere along the Rio Ancoa but you may want to head back to town for a more comfortable and service oriented campground.
