Gem of the East Bay: Rock City trail at Mt Diablo State Park

510 Families reader Christa posted photos of her family exploring Rock City at Mt Diablo State Park and it reminded me that I’ve always wanted to go there.

Mt. Diablo State Park is near Walnut Creek (North Gate Road into the park) and Danville (South Gate Road). Within the park there are numerous hiking trails and recreation areas; Rock City is just one of them.

Access Rock City via South Gate Road which you’ll reach by driving on Mt Diablo Scenic Road from Danville. Christa wrote that it’s well-marked with plenty of parking.

“Great rock-scampering and sandstone wind caves for explorers of all ages,” she said.

If you find yourself dragging kids to The Container Store or some other Walnut Creek destination, keep this little adventure in your back pocket.
