Top Ten Mexico Classic Adventures

Lace up those boots: Verdant pine forests, superb hiking and biking trails, and great climbing are not only accessible, they're just a 30-minute drive from Mexico City. You can find all this in San Nicolas Park, in the heart of the Ajusco Mountains. The trail system is a novelty in Mexico, so don't miss taking advantage. And, as with most things in Mexico, the park's a bargain: The entrance fee is about $1, or a little more with guided service. There is no better Mexican example of a community-run natural park than this one, and it's already inspiring other nearby communities. Something to come back for: Soon the Ajusco Mountains will be honeycombed with well-marked hiking and biking trails.
