“Access to the Nitro trails from 603 Trail and McCullough Hills Trail.”
— Reid Litchfield
This trail provides access to the Nitro trails from 603 Trail. Turn left onto McCullough Hills trail as the 603 Trail meets it and continue until you meet the old 4WD trail that runs below the power lines. Turn right and follow the singletrack. There are several crossings across the wash, which are well-marked. The trail is pretty flat overall. There are some mountain bike features that can be fun to note as you run past, but they won't interrupt your outing. Traveling to the south is slightly uphill, but you'll enjoy a quick trip home as you descend back to the trailhead.
