At the eastern fringe of the San Francisco Bay Region, Mount Diablo, elevation 3,849 feet, stands alone on the edge of California’s great Central Valley. At this point, the Coast Range consists only of low hills, none high enough to block the view from the upper slopes of the mountain. As a result, the view is spectacular. 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, 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 meet to form the twisting waterways of the Delta. To the east beyond California’s great Central Valley, the crest of the Sierra Nevada seems to float in space. With binoculars, you may even be able to pick out Half Dome in Yosemite National Park. Mount Diablo State Park is one of the ecological treasures of the San Francisco Bay Area. Every season in the park has its special qualities. Discover for yourself the mountain's beautiful wildflowers, its extensive trail system, fascinating wildlife and distinctive rock formations. View the stars from its lofty heights, bike ride to its 3,849 foot summit or explore the more remote trails by horseback. The park offers hiking, biking, horseback riding and camping. Dogs must be on a leash under your control at all times. Dogs are not allowed on trails. Dogs must be in a tent, camper or enclosed vehicle during the night. Gates open 8am and close at sunset. Visitors should plan to be in their vehicles by sunset and headed out to avoid being locked in.

We started from Juniper camp ground. It's hard and no shade at all. There are a lot of gravel which makes it tough will climbing down.

Good trail! Man that incline was no joke nor were the narrow trail at some point! Those views though are definitely worth it! The water falls/ streams were great and provided cool water to cool off with! Will definitely do this again!

Good short hike, with nice stretches of uphill to keep you working hard. Great view from the top. Spring is a great time of year with the flowers. If you go up and back from the east side you can stay in the shade in the afternoon.

Very pretty in the spring with the wildflowers. It can get windy up top, so you might want a lightweight jacket if you hang out up there to rest.

That hill though! This is my favorite road/trail for a quick, intense climb. Easy to add a trip to Falls Trail or to loop around to Mitchell Canyon. Wide fire roads mainly (meaning there are no snakes hiding in the grass or on the rocks!!),

So beautiful. Moderate to hard. Great views. Flowers water peace!

I turned this into a 4 summit hike/run which looks just like a chicken. If you're strictly hiking this then it's definitely an all day hike and probably as hard as it gets but well worth it. You are able to summit all 4 main peaks in one day and get a leg burning workout since this involves about 5k in elevation gain. Great terrain (you only backtrack a little after the main summit) but watch out for the poison oak and bring plenty of water especially for the last Eagle Peak push since it's exposed and the sun will be fully up by that time. I would suggest bring at least enough water to reach the main summit where you can refill. Don't give up after the first peak, that's going to take a lot out of you since it's the furthest climb up but after that it's smaller ascends/descends.
