Excellent trails.
From North Richmond and Pinole, take I-80 west to the McBryde exit. At the bottom of the ramp, turn left onto Mcbryde Ave. Follow McBryde to the second stop sign. The ornamental stone pillars to your left mark the entrance to Alvarado Park. Proceed straight through the stop sign onto Park Ave. for approximately 1/4 mile to reach the Wildcat Canyon staging area.
