This mountain pass is the main transport route across the border from Santiago, Chile into Mendoza, Argentina and gets a lot of traffic. But it’s not exactly an easy, pleasant drive, as you can see from the video below.
The Paso Internacional Los Libertadores, also called Paso Del Cristo Redentor, is called Los Caracoles or “Snails Pass” by locals. The steep road has no side rails and is covered with snow almost the entire year.
From the Argentine side, the route to the pass is a slow, gentle incline that enters a tunnel at 10,500 feet of elevation. On the Chilean side, the road descends down a long series of switchbacks.
In September 2013, the pass had to be closed for ten hours after about 15 – 20 inches of snowfall, and nearly 15,000 people were stranded on the Argentine side.
