The most common route Mexico’s third highest mountain – at 17,159 feet –  is La Arista del Sol (The Ridge of the Sun), which climbs up the “Sleeping Lady’s” feet, past her knees and across her stomach. Ascents of this extinct volcano are the most attractive climbs in the country. Very few technical skills are necessary for scaling it, but acclimatization is vital to success.
