From Rock City hike up to the summit. This trial offers scenic views and breathtaking climbs. Although steep in sections, it is a great hike. This park is one of the ecological treasures of the San Francisco Bay Area. Many visitors to Mount Diablo head straight for the summit to enjoy the famous view. Summer days are sometimes hazy, and the best viewing is often on the day after a winter storm. Then, you can look to the west, beyond the Golden Gate Bridge, to the Farallon Islands; southeast to the James Lick Observatory on Mount Hamilton at 4,213 feet elevation; south to Mount Loma Prieta in the Santa Cruz Mountains at 3,791 feet elevation, north to Mount Saint Helena in the Coast Range at 4,344 feet elevation, and still farther north to Mount Lassen in the Cascades at 10,466 feet. North and east of Mount Diablo the San Joaquin and Sacramento Rivers converge to form the twisting waterways of the Delta. To the east beyond Califomia's great central valley, the crest of the Sierra Nevada seems to float in space.

Try not to get yourself to tired at Rock city, before this hike, as it gets pretty steep in parts. "a trail through time" is nice but a little narrow do to poison oak. the mountain is covered with wild flowers and other blooms this year.

If you park near rock city which that is where your GPS will take you, there isn't very much of a hike. The trail was more touristy, so expect alot of people. It was nice when you're alone and the trail veers off here and there. The main trail is the "trail through time" and is pretty much the main trail. There are some if you go opposite of Rock city. It's nice for a first time visit, but I probably won't be going again. And it's also in a state Park, so expect to pay $10 at the gate and a lot of bike riders on the road. Very much a main stream trail
