The park is managed as an 'ejido,' a communal land-holding system originating from Mexican agrarian reform.
The forest serves as a vital catchment area, recharging the aquifers that supply water to southern Mexico City.
It is one of the few places in the metropolitan area that maintains a high-altitude coniferous forest climate.
The park's trail system was specifically designed to meet international standards for competitive mountain biking events.
The terrain includes volcanic soil features typical of the Trans-Mexican Volcanic Belt.
Parque Ejidal San Nicolás Totolapan is an extensive forest conservation area located on the slopes of the Ajusco volcano in Mexico City. It serves as a primary site for mountain biking, offering a network of technical tracks ranging from beginner-friendly paths to professional-grade downhill courses. The park also hosts specialized ATV circuits that navigate through the dense pine and oyamel fir woodland. It is an ejido-managed park, meaning the land is collectively owned and maintained by the local community. The ecosystem features high-altitude vegetation and provides vital environmental services to the city, including water infiltration. Visitors encounter a mountainous terrain with significant changes in elevation. The area is equipped with designated zones for picnics and recreational outdoor activities. Its geography allows for views of the surrounding volcanic axis of the Valley of Mexico.
The high-elevation vantage points near the mountain biking circuit summits offer panoramic views of the forest canopy and the southern Mexico City basin.
Rent mountain biking gear locally if you do not want to transport your own equipment up the mountain.
Wear layers, as the high-altitude climate causes rapid temperature drops once the sun sets or cloud cover moves in.
Stick to marked trails to avoid damaging protected vegetation or wandering into restricted forestry zones.
Do not attempt difficult mountain biking tracks without prior experience, as the altitude and technical terrain are demanding even for active individuals.
Open daily, but access to specific technical trails may be restricted during heavy rainy season storms for safety and soil preservation.
Practice 'Leave No Trace' principles; do not litter or disturb local wildlife. Wear closed-toe athletic footwear appropriate for uneven, rocky terrain.
