The Jocotitlán volcano or Xocotépetl is an isolated volcano and is the tallest peak in the immediate area. It is inactive with an altitude of 3,928 meters above sea level at its peak, rising 1,300 meters above valley floor. The volcano developed during the Pleistocene of andesitic-to-dacitic lava flows. The most prominent feature of the volcano is a horseshoe-shaped escarpment open to the northeast that formed as a result of gravitational failure of the summit during the early Holocene. The resulting debris-avalanche deposit covers an eighty km2 area to the northeast, although much of soils all around contain volcanic residues. The last known eruption occurred about 700 years ago, but there is still a possibility of it reactivating and should be monitored. The volcano is part of an ecological reserve as part of the Isidro Fabela State Park. On the road that leads up the volcano, there is a statue of the Virgin Mary. This road leads to a lookout point at the top, which allows for a view of about forty km in all directions. Visible from the valley floor are the radio and television transmission towers that are at the top.
