Great trails with balance of sun and shade

Great summer/fall trail. Bikes can go very fast on parts of the trail. I would avoid in the rainy season.

Beautiful, challenging trail!

Extremely hot. I started at 9am and it was hot off the bat. Not much shade until you return. Intense climb going all the way up and some rock scrambling with a nice peaceful partially shaded fire trail on the way back. Lots of dragonflies and butterflies no big animals. Overall challenging especially with the heat but you feel very accomplished. Make sure to start early and bring LOTS of water. Fountain at the visitor center, the other parking lot at the top, the fountain is broken.

Reviews are right. Hard, great views.

No parking. I don’t mean limited, or just a few spots. I mean the street is lined with boulders to prevent anyone from parking anywhere near the trailhead. You cannot park anywhere near the trailhead. I drove on and hiked from rick city

If you’re like me and like a reward at the end of your hike, do NOT do this counter clockwise! Save the summit for the end. Get the fire road out of the way first. Some very steep parts, make sure there’s decent tread on your boots. Awesome workout with great views.

Great fun. Cows, dry creek beds (Aug), mixture of grades, nice views. Nice hike.

Made Dipsea (MV, Stinson & back) feel like a walk in the park. Certainly the heat (83?) and little shade factored, but the 8 up (clockwise) was UP. An accomplishment for sure. Make sure to leave well before noon (we didn’t and got back in the dark) and bring a lot of water.

Challenging but fun loop. I would recommend this hike for anyone in decent shape.

New favorite route to summit. Views along the way are great. Don’t recommend on a 90+ degree day

great wildlife, little shade and some nice - but not extraordinary - views. Still, a nice hike to feel refreshed and energized. I did this hike late morning and it was hot. If hear bothers you, go much earlier.

Stunning hike. Breathtaking views!!! Bring lots of water, the hike up is steep, but you can refill at the top. Lots of sunscreen because the top part is pretty exposed. Take the steep part along the ridge line up and take the fire road down if you like your knees.

Great, semi-secluded trail. Definitely not an easy hike. It's basically uphill the whole way with a pretty aggressive start.

It is a nice trail for a quick 2-3 hours hike. Nice scenery. I guess it would be really nice in spring time. Worth coming back that time.

Great trail for a running workout. The inclines are hard. There is hardly any shade. I would only recommend experienced runners to run the course if you choose to trail run.

Canceled due to my. Lion

It started out great! Nice fire road, but near the second half it became single track trail full of stickers and a steep decline.

Recommend starting right by the Mitchell Canyon Visitor Center and using the map/trail instruction sheet they provide, makes for very easy navigation. folks on iPhone maps looked lost. $6 parking, bring exact $6 (no change, just an envelope you fill out). Challenging first half - steep climbs for the first 6.5 miles or so. Not horrible but definitely challenging. Started at noon, enjoyed the afternoon cool winds during the second half of the hike coming down from the Summit. Took 6 hours with 30 minutes of rest at various points of the initial climb. Great workout and diverse terrain with fantastic views.

ok we did this midday in July probably not optimal timing but still a good hike. winter & spring depending on rains will be terrific. pretty easy to follow with a number of options. beautiful rock formations. not too many people - and a public pool if you are so inspired after your hike. *people please bring water for your dogs!* i helped out a couple folks whose dogs were obviously distressed. no matter the weather just bring it. your dog will thank you

Disappointing. While there are some pretty stretches (Little Yosemite, Pine Canyon), much of the hike is along or adjacent to paved roads.

Great hike! A couple of friends and I went counterclockwise on the hike and we loved all of the views, it was a great workout and definitely plan on going again

a few big uphill parts at the end that we weren’t expecting but made it through.

Fantastic training hike. Wasn’t too hot, and some great views from the top (including a fire in Pittsburg). Highly recommend you do it clockwise to have it easier on the knees on descent. Also recommend you take a detour to avoid the Bald Ridge Trail by taking the Meridian Road to the Prospector’s Gap Rd after coming down off Eagle’s Peak - the Bald Ridge trail is extremely narrow with lots of poison oak and not great trail conditions.

Completed a version of this trek yesterday. I went up Eagle Peak trail and came down Mitchell Canyon. Going up was awesome. I wouldn’t come back down M.C. again though. Very little... and I mean very little views on Mitchell Canyon. I’ll do a figure 8 next time; intersecting at Eagle Peak/Bald Ridge & Meridian Ridge/Back Creek. Still lots of wild flowers and animals running around. Saw deer, turkey, rabbits, squirrels, lots of birds and a little snake. Saw no one on the way up, but a few hikers and bikers on the way down. Another reason to stay off Mitchell Canyon.

Very nice hike and a real workout! I did it clockwise today but have done it counter clockwise in the past and like both directions.

This is a nice hike and a great workout. Our totals showed 14 miles round trip and just under 3,500 feet of gain. Beautiful views of the Bay all along the way.
