Conquering the Milagrosa and Molino Basin: Tucson’s Premier Desert Ride

The Milagrosa and Molino Basin trails in Tucson offer a quintessential desert mountain biking experience with a mix of steep descents, technical terrain, and sweeping vistas. Starting near Mt. Lemmon, this ride is known for its intense challenges and rewarding scenery. The route descends into the Molino Basin before offering two options: climb back out or connect to the Arizona Trail for a more extended adventure that ends at Reddington Pass. This ride is a favorite among advanced riders seeking rugged terrain and breathtaking desert landscapes.

With a total distance of approximately 20 miles when following the Arizona Trail to Reddington Pass, this is not a ride for the faint-hearted. Riders should come prepared for remote sections, rocky challenges, and the logistical demands of a shuttle setup. But for those who tackle it, the Milagrosa and Molino Basin trails deliver a mix of adrenaline and awe, capped off by the serenity of Tucson’s open desert.
