Mount Graham Professional Review and Guide
"At 10,700 feet, Mount Graham is the tallest of the “sky islands” of Coronado National Forest. Due to the conspicuous lack of wilderness designation on the mountain, it is also perhaps the most overlooked riding area in all of Arizona. There are two distinct loops in the Pinalenos, recently built by the Forest Service specifically for mountain bikers. The loop to the north, the Cunningham Loop, follows old logging roads around a steep slope, providing incredible views into the desert 5,000 feet below.
The trail fades back and forth between singletrack and doubletrack; after a few more years it will all be singletrack. The thorny bushes that grow on the other track and in the median between the ruts are huge incentives to stay on the singletrack—bring tube sealant! There’s also one substantial climb, ending with a wild set of switchbacks back down. Trail Surface: The trail is a mix of old logging roads that are being converted to singletrack, and some fresh new singletrack that’s been decently cut by the Forest Service specifically for mountain bikers."
