From the trailhead parking at South Higuera/Ontario/101, head to the north and stay right to access the North Loop. The trail crosses a drainage, then climbs up and over a foothill and cattle guard before descending gradually to a Sycamore and a bridge a couple drainages over.
From here, the trail climbs a bit steeply past some Yucca, then up a shaded oak canyon. At the back of the canyon, stay left as the trail follows an easy contour through the shade of some oaks. Right is the Filipponi Trail
. Though you've been traveling through some shade, the trail can be exposed at times. After crossing a cattle guard, you can stay right for the South Loop
or take the left to head back to the trailhead.
