This is one of the most beautiful drives I have ever taken. The majestic Andes Mountains set behind rolling vineyards and beautiful fields. The road that climbs to the border is world famous (I think its been on one of those most dangerous roads shows). There are 29 steep curves; with a sign counting each one (just in case you forget how long you have to go). The mountains are so steep it’s like a wall of shear ice and there is a waterfall running down the side. This pass is in the shadow of the tallest mountain in the Americas. Mnt. Aconagua is over 22,000 feet tall and heavy snow sits on its jagged peaks. I never saw the movie, “Seven years in Tibet”, but this is where they filmed it in case that is something you really wanted to know.
