In the State of Mexico’s “Pueblo Magico,” otherwise known as Tepotzotlán, you’ll find candy markets, fortune-telling canaries, and bubble-blowing grandmothers dancing to live music in the town square.

Just a few miles away, you’ll find Arcos de Sitio, which is also referred to as The Aqueduct of Xalpa. Built by the Jesuits in between the 18th and 19th centuries, it once carried water from the Oro River of Tepoxotlan.

The aqueduct is 200 feet high and has four levels of arches, making it the highest aqueduct in Latin America. While the structure no longer carries water, it does carry people. That is, you can walk along the aqueduct to get a better look at it and the canyon below.

Or you can zip line across the canyon. It’s the fastest and most interesting way to view this monumental structure. But it’s not for the faint of heart—the area the zip line covers is longer than two football fields. But it’s a once-in-a-lifetime opportunity to go aqueduct zip lining.
