Is there any Argetina skiing close to Buenos Aires?

not meaning to be a dick.. but why didn't you just look at a map?
anyway i've never been to argentina, but basically buenos aires is on the east coast of argentina and the ski resorts are all in the Andes, which run down the west coast (more or less).. so the short answer.. is no.. you would have to fly internally to get to the mountains.. and las lenas might be the closest? i mean compared to say New York, you are close but..

Bariloche is on the other side of the country; not trying to rain on your parade. The closest ski resort is Vallecitos, but it is still about 1,030 km (about 640 miles) away from Buenos Aires. If you go to Vallecitos, you are 33 km (about 20 miles) from Las Lenas. Valle Nevado is 63 km (about 39 miles) from Vallecitos and El Colorado is another 5 km (3 miles) from Valle Nevado.

everything is pretty far from buenos aires. closest on the north side are penitentes, vallecitos and las lenas. aroun 1000kms (640 miles aprox) and if you go to the south like 1000 miles you;ll find bariloche, bayo and san martin de los andes...
if you keep going south u;ll find la hoya 150 miles from bariloche, and then it's usuhuaia at the very south of the country (FAR FAR Away)
plane arent that expensive though and u also have buses to all the resorts from BS AS...
hope it works
