A long ride on the eastern edge of Tucson. Started at Aqua Caliente park, rode up Reddington Pass road and then a series of dirt roads on the way to Chiva Falls. Then turned off to another couple of dirt roads and finally hit the single track of Arizona Trail. Then we travelled north and northwest on a relatively new and untravelled section of Arizona Trail. In the upper part of Milagrosa Canyon, AZ trail goes on a dirt road a bit. Then there is a faint turnoff left onto hairy Milagrosa Trail, that follows a rocky ridge between Milagrosa and Aqua Caliente Canyons before descending to Milagrosa. Several severe sections on this part (mostly walked), and many less severe but still freaky sections. We were spit out on a subdivision dirt road and returned back to Aqua Caliente Park on a short road ride.
