The Nariz del Diablo is a 765m sheer cliff of solid rock traversed by a round-trip tourist train. In 1902 track engineers devised a clever way up this monster by carving a zigzag route into the side of the mountain (many lives were lost in the process). The train tugs a bit north, switches track, tugs a bit south and again switches track, slowly making its way up and down the Devil’s Nose.

Tickets often sell out in advance; book ahead.
