Paso Internacional Los Libertadores – Andes, Chile
A famous mountain pass in the Andes, the Paso Internacional Los Libertadores, is also called the snail’s pass because travelers must traverse it slowly or have tires with phenomenal road grip. Without any guard rails and numerous switchbacks, this route can get dangerous beyond belief and is therefore closed for most of the year due to the harsh weather in the area.
This road is the most beautiful of the 40 border crossings between Chile and Argentina. Like many other mentions on this list, tourists usually go up and down this serpentine highway only to soak in the mesmerizing views.
