Argentina like Chile is a visit in August if you want to ski and see Snow. Buenos Aires is a very large city from there we went to Las Lenas which is the biggest ski area in Argentina. The Andes are breathtaking. They did look different that the mountains in Chile in the fact that the rock was tan and brown and the Chile resort had more black rocks. Since the Andes are over a thousand miles long down the spine of the two countries it makes sense that there would be variations. I wish we could have stayed longer as they got a huge snowstorm the night before we left to go home.
