Malargüe is located 186 km south of San Rafael. It's a small town and serves as a good base for exploring some of the least known, but spectacular landscapes in Argentina.

Highlights:

:: Malargüe Planetarium: has interesting guided visits and interactive daily sky shows (some in English). Pierre Auger Cosmic Ray Observatory, studies ultra-high energy cosmic rays (free daily visits except weekends). Both are located in Malargüe town.

:: Caverna de Las Brujas: Literally translates into "The Witches' Cave". It is a marvellous cave that plunges deep into the earth at a depth of almost 2000 m. 

:: The Payunia: It is recognized as being one of the most densely covered volcanic regions in the world. Trails of lava debris can be seen at various points throughout the park, and enormous boulders of igneous rocks are scattered over the dark plains.

:: Laguna Llancanelo: It is vast shallow lagoon, great spot for bird watchers since pink flamingos, swans and some other 73 different bird species are commonly seen here.

:: Cascadas de Manqui-Malal:  An ideal spot for hiking and abseiling. Keep your eyes alert for commonly seen fossils and for the condors soaring above the high walls.

:: Castillos de Pincheira:  It is a naturally formed structure sculpted throughout the many years by glacier erosion.  It's shaped like a giant castle, hence the name.

:: Las Leñas: Located 70 km from Malargüe, this internationally renowned ski resort is ideal for winter sport enthusiasts of all levels. Summer activities are also offered.
