Looming over the picturesque vineyards of Mendoza in northwest Argentina, Cerro Aconcagua tops out at 22,841 feet. That makes it the tallest mountain in the world outside of Asia, bigger than Mount McKinley or Kilimanjaro. Only the Himalaya are higher. Best of all, Aconcagua is an easy day trip outside the wine-region hub of Mendoza.
