Réserve de biosphère San Guillermo, Biosphere reserve in San Juan Province, Argentina.
Reserva de la Biosfera San Guillermo is a large protected area in San Juan Province that encompasses both high mountain regions and arid landscapes. It spans territory with vastly different elevation zones and contains a variety of habitats.
The area was long home to indigenous peoples who used natural resources and held sacred ceremonies in this landscape. These earlier inhabitants left behind archaeological traces that remain visible in the territory today.
Local communities near the reserve maintain traditional ways of life that are closely tied to the landscape. Visitors can observe these practices in settlements around the reserve's edge.
The reserve has designated entry points with information centers where visitors can orient themselves before exploring. Camping areas exist in specific zones, and hikers should be aware of strict environmental guidelines.
The territory is home to rare animals like vicunas and Andean condors that thrive in this elevation. The contrast between two different vegetation types creates an unusual natural transition within the same protected area.
