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 one of the best in the bay. Many visitors to Mt. Diablo head straight for the summit to enjoy the famous view from the observation deck area. 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 with entrances in Walnut Creek, Black Hawk, and Danville. 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. There are plenty of picnic areas as well as camping at Juniper Campground. Road bikers enjoy rides up North Gate or South Gate Road and the descents are just as fun. Mountain biking is also possible on many of the single track trails. Gates open 8am and close at sunset. Visitors should plan on being back at the parking area to be in their vehicles by sunset and headed out to avoid being locked in.

Wow! Great trail! I added on Foothills Trail to bring the hike in at 8.3 miles. Love all the rock formations, streams, woods and rolling hills! After more rain, should see a waterfall too! I didn’t feel that it was a hard trail, definitely moderate but not hard.

Just a little strenuous and good views. Usually not too crowded.

great workout did trail in 8 hours with about a 20 minute break at mount diablo peak

Good training for the big boys like shasta or whitney. lots of elevation gain. took me 4.5 hours to do it all and i was beat.

Amazing in the winter with rain and fog. I expected it to be a bit tougher but maybe with the heat of spring or summer it earns that hard rating. I’d highly recommend doing it on an overcast day like today though.

Great hike, was able to complete in 3 hours. Pretty challenging climb, and rewarded with gorgeous views of the area. Finding the start of the trail was a bit tough since there isn’t any service at the campground where I parked, but once on the trail the markings were easy to follow. I absolutely encourage anyone looking for a tough 8 mile hike to try this out!

Spring is best for the wildflowers here.

Another great Diablo loop from Mitchell trail.

Great loop hike. Spring time perfect.

It is hard. You’ll wear out your boots. So steep, especially that last stretch at the top. But gotta try it at least once.

A challenging hike that explores the diversity of Mt Diablo. Bring plenty of water (4L) or a filtration kit; you can only refill at the South Gate camp ground.
Lots of exposure so start very early to avoid heat and complete before dark. Hiking poles recommended as legs will be tired at the end. Please post your experience with this hike when you’re done. Safe hiking!

Absolutely beautiful hike! I will definitely be back in early spring to see the creek in action as well as the waterfalls and wildflowers.

This trail has it all - wonderful views, awesome gnarly trees, manzanitas, rocky creek bed, and beautiful Mount Diablo. I would classify this as an arduous ascent up the mountain for the first half although, to be fair I haven't hiked in a while so maybe it felt more intense for me then for those who hike regularly.

Great hiking particularly in early spring and fall.

fabulous!
I did this loop from Juniper Campground, so I had about 4 extra miles added on in order to get to and from the camping site. Went down deer flat road to the trail, took the loop clockwise from there, going down Mitchell Canyon Road and back up Mitchell Rock trail and Twin Peaks Trail.
Twas grand in the fall! all the leaves were changle.
Mitchel Canyon Road is a fire road, it's smooth and wide. I really enjoyed the 2nd half of the trail, going up mitchell rock trail and eagle peak trail, because it's a little more rugged and adventurous: narrow path, more rocks to step and climb over. but nothing too strenuous. don't get me wrong though, it was tough. but do-able. I was very grateful that I brought hiking poles. it was also pretty hot- even in mid-October. it was like, 80 degrees.
of course the views were sensational form each peak. From Eagle Peak, I saw beautiful dark mountains. they looked completely black, but they were really just covered in deep green chaparral.
Twas a quiet trail, I saw a handful of people, but it was a week day.
I reached Deer Flat road as the sun was starting to descend in the sky, and the lighting was gorgeous on the hills. It turned all the yellow into gold.
I highly recommend this hike, especially if you are staying at Juniper Campground. and I highly recommend Juniper Campground too.

I underestimated this trail. it was challenging. You will be rewarded with a nice view once you reach North peak. start early, carry enough water. I think the hike is more like 10.5 miles.

I was excited for this one after getting to the Mt Olympia summit the week before. The views are great but the vast majority of the trail is a big, dirt access road so it’s often hard to feel like you’re in the wilderness. Also the peak is overcrowded with the people that drive there, however the little museum inside is pretty neat. Decent elevation gain but wasn’t as strenuous as I was expecting. Lastly it’s easy to feel like you’re cheating as the trailhead starts at 1000ft.

This hike will easily separate the mountain goats from the average hiker. Expect to finish in 4-5 hours if you are average. I smoked this bad boy in sub 3 hours including all my small breaks. Not the prettiest hike in the world but it’s a great workout if you get after it! Make sure you have decent grip on your shoes... I went clockwise and really glad I did. It will start off steep and have lots of loose rocks. Some parts were pretty tricky to get down (for me at least) because it was so steep and my shoes didn’t have the best traction. Once you make it up to the top it’s a pretty smooth and easy way back if you go clockwise. Holla at ya boy if you get sub 3 hours on this one!

Despite many warnings and being advised not too, I hiked this trail for my first time hiking ever. I do not recommend it as it is extremely difficult and in some spots maybe alittle dangerous but I made it, it was well worth loosing the ability to move the next few days and I completed it in about 8 hours!

So happy to see all pushing for this loop! Such a beautiful time on the trail.

nice trail...I want to go back again...

Didn't plan on this trail but we ended up here. So glad we did! Hard incline at first, but worth it when we got to the lighthouse at the top. So beautiful. Air was fresh, weather was cool. They scenery absolutely gorgeous.

It is longer than 12. Great hike overall. For the big ballers. Soreness is a virtue

Since I live nearby, I hike this trail often. Of course, during the summer months, hiking the trail early is a must. Bring lots of water and a hat . I enjoyed the hike during the winter and spring season when the waterfall is there and the mountain is beautifully green. I would always recommend this hike.

simple pastoral trail typical of the East Bay hills. nothing particularly impressive. the day was beautiful and clear skies made for a picturesque hike.

Nice and challenging hike, with great views. The heat was brutal even though I left early and hiked up in the shade.

Beautiful hike for the ready and capable. Not a hike for everyone as seen by the hard eating. A nice thing to know is there are water faucets at the top to refill backpacks or bottles.

Very nice and quiet hike with hardly any traffic. Took about 3 hours at a reasonable pace with a few stops. Great views! Some areas have moderate+ gradient, especially around the Falls Trail loop. Better to go clockwise around this loop. The creek and waterfalls were all dry. Be prepared with hat, sunscreen, and plenty of water since it was a hot 90 degrees by mid-afternoon.

It was a good challenging with a rewarding view at the summit. Some of the roads are rocky, narrow and easy to lose your footstep. Definitely recommend start out clockwise loop because at the end it will all be flat and easy fire roads for your tired legs. We took our time and enjoyed the scenery of rolling hills and mountains. My phone said 14.6 miles total because we climbed up to the summit. There was ice creams (cone and sandwich) at the visitor center for your cold sweet fix. Overall, this is a very nice trail! Prepare to spend quite a bit of time conquering it. No less than 4 hours unless you’re extremely competitive ;)!

Great workout! I was grateful for the recommendation to go clockwise to start with the single track uphill- would have been very difficult down that way. Beautiful views! Didn’t see another person until the visitor center

Great hike with amazing views of the bay, Diablo and beyond. Uphill and downhill struggle pretty much the whole way! It took us 7.5 hours to do (moving time). This is much longer hiking time for us as the downhill is steep fairly frequently with poor grip. If you can stand the burn and blisters it’s definitely worth it!
