El Ticlio
Winding around Mount Toromocho at an elevation of 4,781 m, El Ticlio is one of the highest mountain passes in the Andes. The train from Lima to Huancayo also goes through here, making it the highest standard gauge railroad in the world. Beautiful scenery, but very hard to breathe. [NOTE: The photo was taken in the mid-1980's. I understand that now there's not as much snow on the peaks].
