Shell Ridge is the City of Walnut Creek's largest open space unit, with trails for biking, hiking and riding through oak woodlands and grassland savannah on the lower flanks of Mount Diablo. Shell Ridge gets its name from the marine fossils left behind when the ocean waters that once covered the area receded.

Interesting rock formations

The very last part of the Ridge Top Trail part of this loop was fenced off, so had to double back and take the bypass trail. Apart from that great hike and phenomenal 360 views from the ridge top.
