Zona Arqueológica Tepozteco
Perched on a mountaintop, this small temple is dedicated to—depending on who you believe—either the Aztec deity Tepoztécatl, the god of the alcoholic drink pulque, or the Ahuizotl, the eighth Aztec emperor. The pyramid was part of a city that has not been uncovered, but was of such importance that pilgrims flocked here from as far away as Guatemala. Today it attracts hikers and sightseers willing to undertake the somewhat arduous climb up a well-maintained but rather steep trail of about a mile each way. At the top you can walk around the base and the top of the pyramid—the view over the valley is absolutely dazzling. Note that the last access to the trailhead is 3 pm. You'll find several snack bars and casual eateries lining the street to the trailhead.
