The Death Road: the name says it all. There used to be about 200 deaths in traffic here every year. Or actually; in the ravine. The road is narrow, winds through the Andes landscape and has a deep abyss on one side.
Currently, it is closed for motorized traffic, but you can ride your mountain bike. The road is unpaved, slippery when wet, and yes, there are still deadly accidents. So make sure you take your time going down el Camino de la Muerte, enjoy the amazing views and the unique experience.
