“One of the very few professionally built and maintained trails in Mexico.
— Jaime Hop
No motorized vehicles allowed on these trails, which is great.
A must-do ride in Valle de Bravo. There are very few professionally built and maintained trails in Mexico. This is one of them, which means it is always in great condition, and it is all rideable without ever having to stop.
This is a fast trail, that just flows. A lot of switchbacks, and only one short section with not too severe exposure. The surface is mostly hardpack, with very little erosion.
Family Friendly: An intermediate trail. Goes up and down constantly, which allows you to catch your breath. Several exit ponts in case you want to end the ride sooner.
There is a main road, from bottom to top, used by cars and trucks to takes people paragliding. Some of the singletrack is just above that main road, so it is easy to miss it.
Beware of other cyclists and hikers. You can ride this trail both ways, so there is always people coming the other way.
Leave your car at the parking lot, which is about 600 meters past the entrance to Monte Alto, driving from Mexico City to Valle de Bravo. Then ride your bike to the entrance of the park. There is a big sign there that says "Monte Alto".
Start on the fire road, and then yield left. This is a system of trails. The epicenter is a small hut where the forest rangers are. You need to pay a small fee there to access the area, since this is a state park. Locals are exempt, though.
No need to head there immediately. You'll end up there later anyway. You can ride it both ways, and choose your loops in no particular order. They all start and end at the rangers hut.
The surface is basically perfect. Very few rocks, obstacles, roots, and no drops. The forest is beautiful, and you can see Valle de Bravo Lake from different points.
