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.

I actually don't know about this hike. I attempted to do it and decided to use the feature in the app of getting directions to the trailhead. Because I have never been to My Diablo I trusted I would end up at the trailhead. The app took me to the east side of the My Diablo to some almost unseen openings in the fence to access fire roads, etc. Just want to inform anyone that they may not end up at the trailhead. I would like to try and do the actual hike someday.

Always great views and amazing talks

Perfect trail for mountain biking.

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

Great trail for a moderate workout. Lots of shade.

Wonderful hike, went with 3 kids (9-11) who managed to make it with time. Would give it 5 starts but there was poison oak EVERYWHERE so keep an eye out. Aside from the poison oak there were wonderful views, will be going again (without kids

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!

Parking was impossible at the start of this trail so we parked at Rock City and hiked the top loop and all around that location. Perfect for kids - lots of shade and great climbing and views. Glad we didn’t start at the bottom after all!

This was a death march

Pretty chill hike, pack water if it’s summer bc it can get hella hot

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.

Great hike. Have good shoes and lots of water on you.

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.

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.

Mostly fire roads. Very quiet with a few bikers, but not very many. I saw some horse evidence, but the trails weren't covered with poop, so they must not do this area very much - thankfully! I didn't do the route as written. I turned right a bit too quickly onto Sulphur Springs Trail from Old Finley Rd not far from the old house. The trail identifier was missing so I thought it was Walnut. I followed this trail to Black Hills Trail where I took a left. I took another left at Crestview Rd and followed that to Highland Ridge where I made a left there. Took a right at Morgan Creek Rd and a left on Jeremiah Trail - which is very overgrown and single track. I hung a left at Finley Rd and followed it out to the trail head. My GPS said I went 6.7 miles from the beginning of the trail head and back. This did not include the small .75 hike back and forth to where I parked. I really enjoyed the quietness of the hike, so much that when a bike came upon me, they startled me!

Next time I will probably throw Grizzly Trail to Highland to Morgan Ridge and around to Finley, but that will be done when it cools down a bit. There are many ways to make a nice hike from this area.

I saw one juvenile rattlesnake on Jeremiah Trail, no surprise there. A few turkeys, and raptor feathers. Not much wildlife to be seen today.
