From the Yuba Trailhead, head South, towards the hills (away from the Bay). You’ll quickly pass beneath El Camino Real. The path runs parallel to Highway 85 for much of its start, then ends at Sleeper and Franklin Avenues in Mountain View (there is a bridge across the creek here that leads to a drinking fountain). Check out 2012 construction to extend the trail farther South, with a branch crossing Highway 85 to the Americana neighborhood of Mountain View, then return back the way you came.
