Mountain Bike? Try 30km Along Ruta de Plata in Mineral de Pozos. I am going to struggle for photos because I have never mountain biked in my life. And yet, there are many daring enough to handle it. The Ruta de Plata is the longest mountain bike trail in Mexico. When I looked briefly at 3 or 4 sites that specialize in mountain bike adventures, Mexico was never mentioned, and no link for Mexico either in the multi country dropdown.
Enthusiasts, take note, and come give a ride a try. The views are amazing. I walk it in parts. Pozos is just fascinating. The terrain, the skies, the vegetation, the wind, the ruins. The bike shop rents all the gear too for the weekenders who come from all over Mexico to ride. I hear there are degrees of difficulties for different paths.
I am going to post some more photos when I take a few more. Here is the small shop below. Keep in mind, Mineral de Pozos, is still a small and unspoiled town…but a few years ago, the Ruta for biking did not yet exist. We are expanding in the right way. Keep the environment as natural as it can be. This may be a starting point to inquire of a mountain biker from San Miguel who has biked Mineral de Pozos.
