Driving and Biking
Biking: Bikes are allowed on all roads open to vehicle traffic. Biking is not allowed on any hiking trail.
The Ajo Mountain Drive (21 miles) is a popular biking road. Please bike defensively, many drivers are looking out the windows at the beautiful scenery and may not be expecting a bicyclist. There are no hiking trails open to bicycling. Please also carry a way to secure your bicycle, if you plan on leaving it for any period of time, anywhere in the monument. The road is open for biking only during daylight hours.
