Las Leñas is a ski resort in Argentina, located in the western part of Mendoza Province.

[6] Las Leñas is located 1,200 km (750 mi) from Buenos Aires, and can be reached by car, bus or airplane.

Aeroplanes make use of the Comodoro D. Ricardo Salomón Airport close to Malargüe, some 95 km from Las Leñas, and the Suboficial Aytes Germano Airport near San Rafael (regular domestic flights) where buses make the connection with Las Leñas.

The road to Las Leñas is paved and seldom blocked by snow, although bad weather or poor surface conditions can sometimes lead to its being temporarily closed by the Gendarmería (border guards).

In 1987 members of the Pan American Sports Organization (PASO) determined that the first Winter Pan American Games should take place in Las Leñas, Argentina in 1989 and be held every four years thereafter, but the lack of snow forced the inaugural Games to be postponed until 1990.

The first Winter Pan American Games were held from September 16 to 22, with 97 athletes from eight nations participating: Argentina, Bolivia, Brazil, Canada, Chile, Colombia, Mexico and United States.
