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!

it was a nice family hike. challenging in a few areas. we never found the water fall :(
but it was a beautiful view

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.

Always great views and amazing talks

Don't be like us - check the weather beforehand so you don't end up hiking here when it's 100° outside

It’s a very nice trail, but extremely tough if you don’t hike more that 5 miles. On my GPS it actually ended up being 14 miles because we did climb to the summit. If you are and experienced hiker go for it, for people like that I’m not in terrible shape but also don’t run marathons it was really tough!

This was a death march

Not the most scenic hike I have done. I hiked during an extreme drought, I was disappointed to find out that the waterfall were completely dried out. The last part of the trail is extremely steep, a hiking stick can really come in handy.

Nice hike with many butterflies, birds. Went left at Deer Flat down Meridian Ridge to Bald ridge to North Peak to Summit. Looped down Juniper trail and back to Mitchell Canyon. very enjoyable day.

Great hike. Highest place I’ve gotten to in my backyard

A long hike with lots of uphill but nothing technical about the hike. We did the counter-clockwise version which was probably a mistake because the downhill is pretty tricky. Probably best to come down along the fire road. Nice views from the top. Best to go in the Spring or Fall, as Summer can be too hot.

So thankful for all of the shade! Definitely saved me on a hot morning. The uphill climbing was a littleeee rough but the views at summit made it all worth it!

Trail was a great length for the evening. Elevation change was just right for a workout and the views and sunset were perfect. Would definitely do this one again.

I seem to have a thing for missing the best hiking time in the spring and starting in the summer when everything is hot, dry, and dying. Did this hike on a hot day (high 80s for most of it). The trail is very exposed so bring plenty of water and sunscreen and maybe a towel for your sweat. There are many spots to appreciate the view but it is very strenuous - we lost a guy on the way up...I hope we see him again someday.

At the base of the peak, we went the wrong way and reached North Peak instead of the main summit (which is about 300ft higher) so we went back down and back up the right way. It didn’t have much consequence besides taking an extra hour and making us feel kind of stupid. I don’t recommend unless you’re really into radio towers.

At the summit there’s a cool museum about the history and wildlife of the mountain. The word “Diablo” was used by Spanish soldiers to describe where a few Native Americans mysteriously escaped, but the mountain itself almost literally rose from the depths of hell (i.e below the earth’s crust).

We also met a cricket with one leg. I asked it how it lost its leg but it just spat at us. I can kind of guess how it lost its leg…or conversely, how it managed to keep the other one.

A leisurely stroll with decent views.

Not for beginners. very steep and thin trail for most of the route. lots of poison oak and thorny grass. please wear full sleeved clothing if going for this hike. parts of the hike are partial shade.

Went on a very hot day (temperature reached about 90 by midday), but started around 7:30 in the morning to avoid most of the heat. Hiked counter-clockwise and glad we did -- the trail was much more technical on the way up, which I prefer. As noted in other reviews, we measured the trail to be about 14 miles instead of 11.9, so that is definitely something to take into consideration. Views from the top of the mountain were really nice as well.

really lovely and wonderful changes of elevations and sceneries

Nice hike. Took about 2 hours at a leisurely pace. Great mix of scenery and views.

A very nice hike, very nice views on the path. It was a bit hot so don’t forget to bring enough water! Especially with kids.

By far my favorite trail this year. I took the Hetherington Loop both ways to get off the fire road a bit. No real waterfalls left, but the creek was still moving a little bit. I stood beside it and it reminded me of the Calm app. Even with the shade, it heats up quickly, so take lots of water and start early. I finished at 11 AM and was sweating pretty good.

I did the loop clockwise as others suggested. Wonderful views as you start ascent. Love getting off the fire road and onto single track. I saw a doe with her two youngsters, turkeys, and lots of lizards. There were some loud talkers and bicyclists early on, but once you get off the main trails, it quiets down a lot.

It’s a challenge on a hot day.

Great trek for my abilities.

Pretty tough hike up a thin trail. You can bring your car past the fire gate all the way up to the trail head if you want.

Summer is not my best friend for hiking inland because it gets too hot and lots of rattle snakes appear. So to avoid it all I went las Tuesday and started at 6am this 11.9 hike in Mt Diablo. Twin peaks, Eagle peak and Mt Diablo Summit. Elevation goes between 300 to 3848ft going up and down the peaks. There is so much wild life out there! I got to see all kinds of insects, birds, deer, rabbits, bobcat, lizards and small snake. Thank goodness, no rattle snakes this time! The views are amazing! If you go early it is much cooler and sometimes there is a lining of fog covering the surrounding cities of Clayton and San Ramon. Pretty much golden and dry during this month except if a creek running parallel to Mitchell Canyon Trail. In spring time Mt Diablo turns completely green and beautiful!
