Located in Patagonia, on the border between Argentina and Chile, Batea Mahuida (not to be confused with Auca Mahuida) owes its name to its shape barrel reversed: Batea, meaning barrel, circular to oblong timber, without handles, used to wash in Mapuche - Mahuida designating a mountain.

The crater of the volcano Batea Mahuida, with a diameter of 5,000 meters, is occupied by a crystalline lake, which freezes in winter.
Dating of samples from the Cerro Batea Mahuida north gives a range between 5.2 and 4.9 Ma, a pre-glacial volcanism.
The last eruption of Batea Mahuida produced a lava flow forming a peninsula in the Aluminé lake, on which stood Villa Pehuenia (see map above). Volcanic sand beaches form along the lakes.
The interest of the volcanic site became touristic : the crater and its lake are easily reachable by car. It became a place of excursions, as well as the summit, a wide panorama reveals near Moquehue and Aluminé lakes, and the border surrounding volcanoes: Villarica, Lanin, Callaqui, Lonquimay and Copahue. In winter, its gentle slopes promote learning to ski ... practiced throughout the region, La Angostura being a station set to the forefront by the ash fallout from the last eruption of Copahue.
