The Sonora Trail is smooth, but hilly, and has a 10-12 mile loop course that is <br />
well marked at intersections. This ride is suitable for many levels, but <br />
beginners should have good cardio and/or be prepared to pace themselves <br />
and take breaks if necessary.
From I17: Jomax Road, Exit 219, and turn east onto Jomax. At the first <br /><br />traffic light turn left onto Norterra Parkway. Drive 1.3 miles to a "T" <br /><br />intersection with a stop sign. Turn right onto N North Valley Parkway. Go <br /><br />about .2 miles and turn left onto Copperhead Trail, then left again in .1 <br /><br />miles onto Melvern Trail. Go another .2 miles and turn right onto Desert <br /><br />Vista Trail. Follow this through the gate to the park and to the trailhead. <br /><br />The parking lot is at the end. This trailhead area is between the Fireside <br /><br />development and the hills.
