Teotenango Archeological Zone is about 25 km (16 mi.) s.e. of Toluca via Mex. 55, the highway to Ixtapan de la Sal, following signs to just n. of the village of Tenango. One of the few archeological zones in Mexico not owned and managed by INAH, the National Institute of Anthropology and History, Teotenango was excavated and developed in 1975. This walled, hilltop site is spread across a flat bluff and comprises the largest group of pyramids in central Mexico after those at Teotihuacán. Multiple low-rise pyramids cover several acres and have a backdrop of snowcapped mountains.
A museum at the site entrance has professionally mounted displays of artifacts found at the site. Clean, orderly and very well maintained, these ruins make an excellent day trip from Mexico City. Bus transportation also is available from Toluca.
Note: A long and steep cobblestone path leads from the parking area up to the pyramids; wear comfortable walking shoes. At an altitude of about 7,000 feet, the 15-minute hike will be arduous for those not in reasonably good shape.
