Hills for Everyone-Four Corners-Telegraph Canyon Loop Professional Review and Guide
"The Hills For Everyone Trail is a hiking only footpath at the east end of Chino Hills State Park. The path follows a seasonal tributary of Aliso Creek through a small draw near the head of Telegraph Canyon. The lush riparian corridor is filled with groves of oak, sycamore, and walnut trees, with an understory of ferns, berry vines, and watercress.
For hundreds of years, the drainage attracted the Gabrieleno Indians for hunting and food gathering. The 1.3-mile meandering footpath has interpretive panels that describe Gabrieleno Indian life, wildlife, and surrounding vegetation. At the west end of the loop is a picnic area and great views at Four Corners (a major trail junction). The trail descends back to the trailhead on the multi-use Telegraph Canyon Trail."
