"This national park will put you in the middle of two of Mexico’s highest peaks: Popocatépetl and Iztaccíhuatl. Popocatépetl has been active since the mid-’90s, and the park’s main parking lot is the closest you can get to this mountain. Don’t worry, the view from here is still impressive. Iztaccíhuatl is not active, and it’s a popular climb among mountaineers, but you can also hike along one of several routes that roam around the volcano. El Paso is an hour drive from Mexico City and can only be reached by car. There are camping areas around Iztaccíhuatl, but you’ll have to come prepared with all-season tents and some good sleeping bags if you plan to stay overnight." - MATADOR_NETWORK
