Did this hike New Year's Day. 45° with windchill, a little too crowded for my tastes, but worth the struggle! 2.5 hours on the ascent; an hour and a half coming down. I suggest starting as early as possible. The crowds my partner and I encountered were probably due to our late morning start. Plenty of bathrooms along the route, but be aware that the summit restrooms may be out of order or locked. Lower summit has picnic tables and restrooms. Next time I will definitely stop there for a break and snacks.

Great hike. If there are better views please tell me where!

Great hike, amazing views. Less traveled than many routes on Diablo. We had wind gusts up to 60 mph, which is unusual, but made it more adventurous. Would strongly recommend for someone who wants a decent workout in a relatively short hike.

A most excellent hike. 15 miles and about 3900 feet of gain. I hiked clockwise like other reviewers have suggested and glad I did. Not as rocky as I thought it would be though. Not much of a view due to clouds and fog but I was not disappointed. Only saw two other hikers. 6.5 hours with a half hour hanging out in the Visitor’s Center having lunch. Can’t wait to hike more trails in this stellar park.

Best Mt. Diablo hike! Today I experienced the strongest winds ever in my life and rain too! Very adventurous experience hiking the ridge lines and cresting the summits in the stormy conditions. Great time!

Got here early last Sunday and it was a quiet hike up with lots of bird song. i loved the views near the top but this is more of a fire road and not a lot of diversity of terrain. Felt accomplished to the to the top in 2 hours and down in am hour and a half. I’d do it again but prefer the Mitchell Canyon ascent for variety.

Just got back into hiking before Thanksgiving and this was a great hike. Challenging; but, wasn't too overwhelming. Took a little detour to the observation center to see the view. That made it worth it. Clear day and beautiful views. Was about 34 degrees when we started. Wore layers. Should have brought gloves and something to cover my ears; but, wasn't horrible. Will definitely do this one again!!

Almost constant elevation gain at a 20-30 degree incline. Beautiful scenery and five posts along the way showing you what periods the rocks are from which is pretty cool and a good reason to stop. Saw hawks, deer, and plenty of little birds along the way. One bathroom up midway and a few on the summit.
Worth it. On a clear day you can supposedly see more land around you than any other point in the continental 48 states.
$10 state park fee to drive up to Rock City.

nice ride. Went new years day and it was brisk and windy..the wind certainly didnt help as it was blowing towards us. the grade can be kinda difficult as the horses make a mess of the trail as it dries. but we powered through..an amazing view of Mt. Diablo summit and the valley. there was a downed bridge in the beginning but its easy to navigate through. probably wont do this trail again though.

This was a challenging one for sure. We started out from the Mitchell Canyon Visitor Center around 10:30am and we went clockwise through Eagle Point Trail. This was the recommended route from many other reviewers, and we are so glad we took their advice. The incline to the summit was at times pretty rough with steep inclines. Especially when you're close to the summit, there were long stretches of just uphill. There is a really nice visitor center at the top for you to learn about the park's ecosystem, and pretty stunning panoramic views of the bay area. It's pretty windy and cold at the top, so dress accordingly. The route back down through the Campground Trail was, thankfully, not too rocky and not slippery, which can be really rough on your knees. It was actually a nice descend as the sun was beginning to set. By the time we got back to the visitor center it was about 5:30pm. My only minor gripe with this trail was that near the summit, you'll see that there are a bunch of cars and tourists that just made the drive up to the summit, and it just kinda takes away from the seclusion you get throughout the entire trip. Otherwise, its definitely a challenging but rewarding hike that you'll be proud to have completed. Just be prepared for it being chilly up top, bring food for the long hike, and bring head lamps just it takes longer than you expect and it gets dark.

Got to the South Gate at 8:00am (there is a self check in just past the gate if the guard is not on time, but the guard showed up promptly at 8am) parked at Rock City, and had the entire mountain to myself. Did not see one hiker on the way up. The signs are worth stopping and reading, great geology lesson. When you get to the summit go to the far end (away from the tower) and there is a little trail that gives you a great view of the city on a clear day. Walk the trail around the summit, great views. Took me a little less then 3 hrs, but it's not a race, enjoy the views and climb a few rocks along the way!

Loved this hike. I thought it was more of a hard hike than moderate. The incline was pretty steep.

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

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!

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.

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.

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.

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.

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 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!

The hike was awesome!!!
I hike with my dad,and we had fun with great views.
And if you want to go drive to mountain,you need to pay 10 dollar, but hike was that much worth.

Very hot day, hike with my 11year old son. The trail was easy walk with great view. Path was very stable, just fun!

This was a great hike... just strenuous enough but not a total killer for one of medium ability... thanks to previous reviewers... it did take 4 hours when you factor in occasional breaks and lunch and a stop to explore visitor center. Thanks also to this app for helping me navigate... made a few wrong turns but was able to quickly correct thanks to gps. The sometimes mediocre signage is why I am only giving 4 stars. Could be greatly improved upon. Bring plenty of water and plan for a work out. I imagine the view can be spectacular but alas it was too smokey when I did the hike to see all that was there.

Perfect trail for mountain biking.
