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 rewards! I started this trail at a Howe Homestead park. Right from the start you have a nice up to get your heart racing. Once you get past the houses and to the top of the first ridge you can stay on top of the ridge to the left, or continue down The trail, which I did. Eventually, staying to the left I took the Shell Ridge Trail. The beautiful views all around me was well worth the non stop ups! I stopped and turned around after I got to the top of the third ridge. I was on a time limit that day and wasn't sure I had enough time to finish the loop. I will hike this trail again, maybe from a different starting point. I was told by a local that a few of the ladies in the Howe Park were responsible for the open space. Also, these connecting trails will take you from city land to county land to state land if you have the time to walk it! Enjoy!
This is a great hike but you need to do it when it is completely dry. The trail crosses what is usually a creek but is completely flooded and requires getting wet to pass if it's been raining. We had to turn back and go through Buckeye Ravine. About 75% of the trail was mud even after 4 days of no rain. The views are great. There are really only two areas of steep incline but besides those, it's an easy hike.

Avoid in rainy days.

Good trail. Decent hike. Scenic. Avoid if it rained recently or if you are going to do it anyway, make sure you wear good trekking shoes. It was muddy when we visited as it rained on three previous day.
