The San Pedro waterfall is one of the most popular nature spaces in Zacatlán. The beautiful waterfall has a drop of approximately 20 meters, and can be seen from above or down to the pool on a sidewalk.
On one side of the waterfall are the ruins of what was the municipality's first Catholic temple in the 16th century. In addition, near this place, are the first pre-Hispanic settlements of what was the Lordship of Zacatlán.
On weekends there is a rappelling and zip line service.
