Two hours east of Mexico City, Iztaccíhuatl at 5,230 meters (17,160 ft) is Mexico's third highest mountain. According to Aztec legend, Iztaccíhuatl was an Aztec princess falsely told that her lover Popocatépetl had died in battle. When the warrior returned to find she had died of grief, he knelt by her body. The gods turned them into mountains - she the dormant snow-covered "sleeping woman" and he the active volcano of Popocatépetl, standing 5,426 m (17,802 ft) to the south. If you hike up three hours on an intermediate trail on Iztaccíhuatl, you'll be rewarded with spectacular views of the Valley of Mexico.
