Estrella Loop Professional Review and Guide
"The West Valley is a mystery to many mountain bikers. The excellent riding in the East Valley, and the critical mass of riders at Arizona State University and Tempe in general, keep many riders from venturing much further west than Central Avenue. Yet cyclists fight for parking spaces every weekend at South Mountain Park, wait in line at the Cactus Cup race loops, or vie with crowds of equestrians and hikers at North Mountain. Look west from any part of the Valley, and, smog levels permitting, you’ll notice several massive mountain ranges out there.
One of these ranges, to the southwest of South Mountain, hides some of the most excellent, and overlooked riding in town. The Sierra Estrellas are dark, jagged, angry-looking mountains, all granite and dotted with dense Sonoran plant life. The softer, older mountains elsewhere in the Valley, especially South Mountain and the Hawes Pass area, are more inviting than the Estrellas. And at first glance, the Estrella’s schist and dark granite appear unmanageably rugged for bikes. Keep looking. The Estrella Loop trail is ideal singletrack for mountain biking, albeit a bit short.
