Now in its third edition, Mexico's Volcanoes covers the third, fifth, and seventh highest mountains in North America -- El Pico de Orizaba, Popocatepetl, and Iztaccihuatl -- and two lesser-known peaks, La Malinche and Nevado de Toluca. This updated guide provides directions to all of the newly constructed roads to approaches and climbing routes, and information on routes that have been closed because of volcanic activity.
