Parque provincial El Tromen

The provincial park spans 30,000 hectares across the departments of Chos Malal and Pehuenches, featuring the Tromen Lagoon and volcanic formations at elevations reaching 3,978 meters.

Established by provincial decree number 1954 on October 15, 1971, the park received international recognition as Argentina's fifteenth Ramsar site in February 2006.

Ten archaeological sites containing aboriginal artifacts have been discovered within the park boundaries, with five locations concentrated near Los Barros Lagoon.

The park entrance lies 7 kilometers northeast of Buta Ranquil town and 27.5 kilometers southwest of Chos Malal, offering access to bird watching locations.

The park shelters the endemic lizard species Liolaemus punmahuida and serves as a nesting ground for 26 waterfowl species, including Andean gulls.
