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.

Lot of parking options, go down near the stables (not the school) for your best options. The start of the hike is pretty average - not much to look at other than Castle rock. Crossed a few very small streams but easy to navigate without getting wet. The back half of the hike is pretty amazing - green wide open space and some interesting rock formations. Few more Mountain bikers & cows on this section but still peaceful

Amazing hike - especially in the morning before it gets busy. Can very different in the winter vs summer.
Lots of options on trails Trail in good condition and plenty of parking

FYI the Little Yosemite portion of the trail was marked with a sign that said no dogs.

If you want to feel that you are in the middle of the Swiss Alps without getting an air ticket, do this hike. It's one of my favorite hikes around. I would say its a Moderate+ but rewarding none the less.

It was beautiful! I went in the morning and loved it. The trail is really muddy, so make sure to bring extra shoes for when you finish.

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.

Great trail for October ...

falcons soaring over head. The beauty of Mt Diablo and the rolling hills set as the back drop of several trail choices. Many fun and low difficulty rating trails.

Good trail, strenuous at times. Excellent views to go with a nice workout.

Followed exact course and GPS said 1,300 ft elev. Also 6 miles. It was beautiful!! Mostly runnable hills except for a few sections. Deer, rabbits, vultures. Some sections torn up by rain and then livestock. Made it more technical than it used to be. If running, highly recommend trail shoes.

Lovely hike through Caste Rock today. It's been breezy and temperatures in the high 60s, low 70s. I saw a family of quail, with lots of little ones still, and a family of turkeys with about 6 youngsters. Water running in the creek still and wildflowers still out but reaching the end.

This was a phenomenal trail! Breathtaking (both from the steepness and view) when you step onto the top of the ridge and have 360 degree views. The only part I didn't like was the paved road that brings you off the ridge if taking the loop in a counter clockwise direction. I will definitely be taking this trail again.

Best for Trail Running! This trail is all dirt with minimal rocky patches. Rolling hills was able to sprint the downhills with no fear of rolling an ankle or hitting a hard rock. The ground felt cushioned beneath my feet. Scenery is rolling hills with chaparral oak trees scattered throughout. No shade so wear sunblock. Pretty fun trail. Came out to 4.97 miles on my Nike+ GPS tracker.

Shell Ridge is close to home for me, so I've been here a lot, ever since I was a kid with my mom. I usually park at Indian Valley school and go from there. Lots of alternative routes you can take in here from fire trails to single-tracks.

Nice hike, moderate, lots of wide fire trails or you can take off on a single-track. Lots of alternate routes you can take here.

Hard, not moderate. The last part has an extremely sharp downgrade.
