I have been meaning to write an article about getting to the Futa for a few years now. The Puerto Montte to Chaiten ferry is simple especially if you have arranged your kayak rental at the Futa. It's not bad either if you are driving a vehicle. Our group, New River Academy high school group of 20 kayakers, take the boat ride annually.
Puerto Montte to Futa Ferry Schedule and Rates
If you take the overnight ferry then you can sleep on the deck, wake to dolphins swimming next to you, pass glaciers, and be well rested for your morning Chaiten arrival. Plus no pesky Argentina border hassles. All those people saying, "you need to have your paper work for the border right," mean it. Read between the lines... lots of folks have been turned back at the border.
Super Cool Carreterra Austral Hornopiren Option
If you want to hit two fantastic rivers en route to the Futa then Hornopiren is worth your effort. Here's how:
A. At Puerto Montte I think you take Ruta 7 around toward Enseñada (Rio Petrohue) follow the famous Carreterra Austral toward Hornopiren.
B. Take a 30 minute ferry for $25/vehicle and then drive another hour and a half to Hornopiren.
C. Rios Negro and Blanco are the gems.
D. Take the Hornopiren to Chaiten ferry.
Stay at Doña Tato's right next to waterfalls on the Negro.
Such a fantastic stop. This is just a remarkable place on the planet.
I am starting a kayaker's hostel in Pucón and would be happy to assist anyone with logistics. Pucón Kayak Hostel has over 50 kayaks available. We might even be willing to bartar a deal for kayaks to go toward the Futa as we are interested in selling boats there.
Feel comfortable to write with your questions we have a wealth of resources and contacts throughout the Chile whitewater community.
