What Travellers Say
Reviews Summary
Visitors rave about the unique and fascinating rock formations at Rock City, especially Elephant Rock and the wind caves, calling it a must-see within Mount Diablo State Park. The opportunity for fun climbing and exploration is a major draw. However, some note that parking can be confusing and that the natural beauty is marred by graffiti on some rocks.
"Rock City was great to see! The rock formations are unique and beautiful. It's easy to walk through and some of the rocks you can climb. I recommend visiting, especially if you're also visiting Mt. Diablo and going through the south gate entrance."
Nabulungi Akinshegun
"This is where Elephant Rock is alongside other rock formations. No restrooms nearby so plan accordingly. This area of Mount Diablo is rugged and steep so be careful especially in damp conditions. The rocks themselves are fascinating, they look like an outdoor art exhibit. People over the years have left their marks on them, literally, and some of the holes in the formation are large enough for children to climb into (please don't let your kids do this)"

"Hike with fun climbing experience. The rocks look very “lively” especially the elephant rock! You can also see wildlife here."
