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.

Great hike to do with the doggie. Easy to find!

Kovar trail is mostly uphill and then you drop down into Indian Valley and head back uphill to Ridge Trail. It's a great hike/run if you're training hills but not much shade so plan for that. All the uphill is worth it because running on top the hill on Ridge trail is really cool.

I parked at the trailhead and followed Stage Road, then onto the Little Yosemite Valley Trail. There was a steep climb. I turned right onto the Briones to Mt. Diablo Regional Trail. Followed the Mokelumne Coast to the Crest Trail, then hiked another steep climb onto the Shell Ridge Trail and went down to the Diablo Scenic Trail. The Diablo Scenic trail led me back to the parking lot. Total 6.3 miles with average 3.0 mph. I got a good workout.

Nice run. Semi-shaded through the Stage road part. Bringing water is essential.

Good hike, not much shade so bring a lot of water in the Summer. Good climb in the beginning and the end, great to run in the middle.

It's a good trail, it's not et all hard or moderate .. It's definitely easy one ... Only thing to remember is that castle rock area use to be close during January to July 31. We was .5 miles close to rock but then came back this time due to close area. But I am gonna redo it on first Saturday of August . The park opens on north gate at 7:30 am.

Evening hike on the peaceful trails of Indian Valley and Shell Ridge, enjoyed the sunset on the way back to the trailhead and saw some deers along the way.

Great hike enjoyed the views. Decent elevation climb. All in all a fun hike. Will be back!

Nice paved road, great view, dog friendly, what else can I ask for?

Beautiful nice long trail but not moderate

I haven't been to Castle Rock in a long time. Great hike - almost 5 miles.

Lots of cows so be careful if you have a dog. Very pretty the pond was nice and cool.

It's a nice fire road trail, however, this time a year roads are trample by the cattle and rough to ride.
Place offers good climbing and downhill fun!!!
