The route starts in Tlalpan, in the south of Mexico City, and mostly follows the Mexico City-Cuernavaca cycling path (Ciclovía Mexico-Morelos).

The entrance is at the Parque Lineal Ciclopista (right behind Carnitas El Puente). Note that the entrance might be locked shut until 8am. The route is most populated at the start, with a mix of walkers, joggers and cyclists on a concrete bike path. It hugs the sides of the mountainous San Andrés Totoltepec and San Miguel Ajusco until you get to the side of Parque Nacional El Tepozteco, eventually leading you down to Tepoztlán.
