Diablo Foothills Regional Park Trails Professional Review and Guide

"If you enjoy a challenging route, take this roller-coaster ride through the foothills just west of Mt. Diablo State Park. Using the Castle Rock, Shell Ridge Loop, Briones-to-Mt. Diablo Regional, Twin Ponds, Hanging Valley, and Stage Road trails, you’ll make two connected loops through the park, with a short jaunt into neighboring Shell Ridge Open Space, enjoying oak savannas, wildflower-dotted hillsides, and a variety of birds. You climb on a single-track trail, past a gate that prevents access by bikes and horses during wet weather. Meeting the Castle Rock Trail, a dirt road, you turn sharply right, then stay left at a fork. The road climbs on a gentle and then moderate grade. Wildflowers on display include California poppies, paintbrush, Ithuriel’s spears, asters, bellardia, Mariposa lilies, and clarkias. At the next junction you also stay left, passing through a blue oak savanna. Gaining a ridgetop, you wind uphill through chaparral—chamise, black sage, toyon, California sagebrush— with a view, left, of impressive sandstone cliffs."

The climb to the top of Shell Ridge was our first intro. We climbed 400 feet in less than 1/2 mile--steep. One needs good tread on the boots. Loved the double loop. Even in June we saw some lingering spring flowers. Hundreds of buckeyes were in full bloom. We saw deer, were followed for a bit by a curious coyote, and lots of ground squirrels and chipmonks. We will be back.
