As with most people, this was our first experience with altitude above 15,000ft. What I would do if I was to do it again would be this: Spend the night at either Paso de Cortes, or La Joya. We stayed in Amecameca, & then early in the morning got a ride to the trailhead (La Joya), then hiked to the Esperanza Lopez Mateos hut. The next day only 2 out of 5 of us were able to reach the summit. This was nothing more than a high altitude hike, but respect the altitude, especially if it's your first time. Once you reach the knees, the angle lessens, but there are many false summits. It was a good experience.

My first "big" mountain was Ixta. Fairly straight forward climbing. A few areas required scrambling. No crampons or ice axe needed. To my surprise and delight I had absolutely no problems with altitude.
