The Rock City Trail is a direct route to the summit of Mount Diablo offering unbeatable views of the Bay Area: Oakland, the bridges, and San Francisco on a clear day. Just outside of Danville, this hike is easily accessible from anywhere in the Bay Area.

Although steep in sections, this trail is a wonderful workout and hikers are more than rewarded for their efforts. The Rock City Trail is a direct route to the summit of Mount Diablo, and the park is an ecological treasure dear to the hearts of Bay Area residents. The best views are on clear days immediately after rain or a storm - if you are lucky, you'll even be able to see the distant Sierra Nevada.

Summit Mount Diablo via Rock City Trail Reviews

This hike is up hill/down hill the entire way. It rarely flattens out, but provides excellent views of the valleys below, or an unreal view of the clouds/fog from above. Leave early and allow plenty of time for this trip, but it’s certainly worth it.
