Penitentes - Mendoza
Snowboarding in Las Lenas is probably as good as it gets in Latin America. Penitentes, is a much smaller resort, but then again, a lot closer to Mendoza.
Most places in Latin America for snowboarding are above the treelines; Las Lenas and Penitentes are no exception. There are not many people snowboarding (and skiing) in Latin America, which means there's never a long wait in front of the lifts, which, on the other hand, might not be as modern as in North America or Europe. Las Lenas does, however, have very modern lifts
