The travelling botanist, Strobell, entered Argentina on an expedition and stayed in a region he named the 'Valley of the Yellow Firewoods' in 1860. More than 100 years later, as a result of numerous studies, the Valley of the Yellow Firewoods was choosen as a place best suited to be a ski center in 1979. In January of 1983 construction of the ski center had begun. By July of that year, the center opened with a hotel with 300 beds. Today, Las Lenas boasts one of the longest slopes in the world (a combination of three intermediate trails) and is one of the largest destination resorts in Argentina.
Las Leñas has several accommodation facilities such as an exclusive five-star hotel, apart-hotels, apartments and dormy-houses, restaurants, an international casino, and a disco.
Snow bus service, ski and snowboard academy offers private and group lessons, workshops for experts, childcare programs, 3 high-mountain restaurants, casino, and an evironmental museum.
