The park was named after four hydroelectric dynamos built to power a textile factory in the town of La Cañada.
The Magdalena River is the only river in Mexico City that has not been redirected into underground sewage tunnels.
The park is located at altitudes ranging from 2,700 to 3,500 meters above sea level.
It is a key habitat for the endemic axolotl of the mountain streams (Ambystoma altamirani), which is distinct from the famous Xochimilco axolotl.
The area is officially part of the 'Bosque de Agua' (Water Forest), an essential ecosystem for recharging the aquifer that supplies Mexico City's water.
The forest composition is dominated by Oyamel (Abies religiosa) and pine trees.
Los Dinamos is a protected natural area in Mexico City centered around the Magdalena River, the last river in the city that remains free-flowing and unpiped. The park spans 2,429 hectares of forest, featuring a rugged canyon with a series of waterfalls and pools. The name 'Dinamos' refers to the four original hydroelectric power plants built in the early 20th century to supply electricity to the city's textile mills. Today, these plants are mostly defunct, but the remnants of the industrial infrastructure remain integrated into the landscape. The park is divided into four distinct zones, with the upper sections offering steeper hiking terrain and lower sections providing more accessible walking paths. It is a critical ecological site for high-altitude coniferous forest conservation within the metropolitan area. The area features extensive networks of trails suitable for hiking, mountain biking, and horseback riding. It functions as a vital 'green lung' for the city, contributing to water recharge and local climate regulation.
The waterfalls at the 'Segundo Dinamo' (Second Dynamo) area offer the most consistent water flow for photography.
Bring a layered waterproof jacket as the microclimate at higher elevations is significantly cooler and prone to rapid mist or rain.
Opt for high-traction hiking boots, as the stone paths and canyon trails are frequently damp and slippery.
Start your hike early in the day to navigate the trails before afternoon cloud cover reduces visibility.
Attempting to drive deep into the park on weekends, as parking is extremely limited and leads to severe traffic congestion; hiking alone on unpopulated trails.
The park is generally accessible daily, but some remote trails may be closed during heavy rainfall months due to mudslide risks.
Strict 'leave no trace' policy; carry all waste out. Dogs must be kept on a leash at all times.
