1 / 7Full Day Tour to Florentino Ameghino Dam from Puerto Madryn
About this activity
This 10-hour excursion from Puerto Madryn travels inland through Patagonian plains to the striking Florentino Ameghino Dam, where 200-metre cliff walls frame an emerald-green reservoir. A rare opportunity to experience the raw, windswept landscapes of Chubut Province and see how this hydroelectric infrastructure integrates into one of Argentina's most dramatic natural settings.
The tour takes along the Route 25, which links the coast with the Chubut mountains. All these miles will take you through the plain landscapes to undulating plateaus until arriving at the Florentino Ameghino. Enjoy the spectacle of nature and be amazed by the emerald green lake which is enclosed by walls, 200 meters high. This serves as a dam and it is much appreciated since it produces electricity for the area. Most of all, you'll be enjoying the magnificent beauty of the nature and landscapes in this area which only exist in a few places in the world.
