If you hike this loop I recommend hiking clockwise. I made the mistake of hiking counter clockwise and could not find where the trail picked back up after crossing the road from Mori point. I was where the trail head should have been, but as always in California quite literally nothing is identified or marked. I searched around for probably 20 min trying to find the hiking trail, but found no success. I ended up on a mountain biking trail that ran kind of close to the hiking trail and figured I could cut across a gulch through some brush to get to the hiking trail. DO NOT DO THIS! Yes the trails are close, but the brush and foliage is thick and there is an area between the two where some homeless people have set up camp. This hike took me 4.5 hours to complete when it should have taken me 3-3.5. Be sure to take plenty of water on this hike as your are exposed for essentially all of it

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.

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!

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!!

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

This is my third time hiking in the area and each time I see something new. This is a great workout with stairs and a good mix of ascending/descending, all with a great view. This is also one of the shorter mileage hikes that features the ridge and the beach.

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!

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

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.

Beautiful trail. Watch out for the poison ivy

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!

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.

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.

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.

Great hike for 360 views around mnt. Diablo. Started at 9:30 from Juniper Campground (note it takes 25-30 min to drive the curvy road full of bicyclists on a Saturday morning from the park entrance.) I took 4 hours 45 min including 30 minutes to explore the summit. Trails are steep at times but never for too long.

Great hike! Lots of shrubbery needs to be trimmed. You end up going downhill for the first mile and a half then making your way up the back loop. Hike ends with an easy downhill. Start early - the trail started to get busy with Juniper Spring hikers around 12, since the trail overlaps.

Hiking on Diablo is one of the biggest reasons why we all over-pay in rent and mortgages. If you’re not making use of such a beautiful mountain, that’s in your backyard, you may as well move to a different state. This is an amazing and challenging hike with phenomenal views, beautiful wildflowers, interesting animals, shade, sun, creeks and lovely smelling vegetation. This hike is full value and I can’t wait to hike it in a wet season to get a different experience. I would give it 4.5 stars only because a couple of areas have poison oak growing over the trail. Not a big deal if you wash everything as soon as you get home, but it slowed my pace and took my eyes off the scenery in some areas. 6 hours moving- 7 hours total.

Thanks to Mike Siders‘ review, I decided to go on this great hike, as I’m in the area for a business trip. I’m glad I did this hike - a great experience in such a beautiful area.

Fantastic hike today! I did it clockwise from Juniper Campground. There are some steep parts with loose gravel on dirt that I wouldn’t want to do going downhill, so I recommend clockwise.
There were so many gorgeous wildflowers! I also saw a coyote. I added on the spur trail to the summit, since I’d never been there.
There’s a lot of poison oak. Most of the trail is wide enough that it’s easily avoided, except for the Bald Ridge section. Wear pants and long sleeves! It goes up to shoulder height.
Most of the trail is exposed, and it felt warm even though it was under 60 degrees when I started. Wouldn’t want to do this on a hot day. I’ll definitely do it again, though!

Wow, this one is a doozy! I followed another review and used Juniper Trail and Meridian Ridge Trail instead of back tracking Not sure if this made it easier or harder but my total distance was just about the same, 16.2 miles and slightly more elevation. I wanted to do more of a loop and was happy about the decision. This is a solid hike but it can get windy on the peaks which can be a bit brutal if you aren't prepared for that. I was actually surprised this hike didn't end up being harder, overall it was super enjoyable but it's definitely a long hike, we finished in a little over 7 hours of moving time. If you want an all day hike and to see all Mt Diablo has to offer, highly recommend this one!

This was a great hike and a great time of year to do it.
Everything was still green and blooming. The marine layer kept it cool today.
We did the hike counter clockwise and added the Juniper and Summit Trail loop to it.

Awesome hike. Do the Moses Ridge out and back off the Juniper Trail (adds 0.8 miles) for some more great views.

We did this clockwise, starting at the parking area in the back of the Juniper campground. Views are amazing as you make a full circle around the summit of Mt. Diablo. There are some rather steep sections in this loop. The Bald Ridge Trail in particular is like a roller coaster, twisting and turning and steeply climbing up and down, but there are some spectacular view points in that section. It tooks us about 4 hours with a lunch break at the summit.
