Beautiful hike! Much of it was shaded, and the terrain wasn’t too difficult.

So beautiful!! Bring a lot of water and go early. A lot of trails and mostly uphill. Walking stick would be useful. Watch for rattlesnakes we saw one on the trail and even saw a baby scorpion!

Beautiful hike. Made it to the trail head (or dead end of a residential road) pretty late morning, but it was still cool enough out that we weren't boiling throughout the hike. Starts out quite mellow, would recommend doing clockwise/going left when you approach the split for the loop, contrary to how the app directs you. Despite the steep bits, little kids were still doing this trail so it's not terribly strenuous. Great views, overall would do it again!

Completed today to accomplish a early morning hike. Truly rewarding morning experience... very pleasant and filled with greenery... Moderately difficult- doable with kids. There is section which needs more effort to climb otherwise a beautiful hike. You will walk alongside of a creek most of the time and the sound from the stream will give you a soothing effect

This hike is a mini version of the Mt. Diablo waterfall hike. It will save you about an hour of hiking and also eliminate the “Second” elevation climb if you are getting tired and don’t wish to complete the waterfall hike. See my review on Mt. Diablo waterfall hike for more details

Such a beautiful hike! My favorite hike in the area! So much to see on this trail! Heard bullfrogs, tons of birds, saw beautiful wild flowers, and wild turkey. The rushing of the water sounds on your right is amazing. Passing through watery paths were pleasantly unexpected. Bring good shoes or hiking bits because of the water and mud. You will not be bored!

Amazing trail with waterfalls, creeks, spectacular views. Started at Regency trailhead, Donner Canyon Road, Fall Trail, Middle Trail, and Back Creek Trail, 7.1 Miles, elevation gain 1,555 feet, moderate hike. Lot of shades and wildflowers.

Did this hike both in winter and spring when I lived close...

First mile (and last mile) really muddy - but loved the hike - great workout for the first 2+ miles and amazing views. Needed to cross 3 very small streams so shoes got a little wet

Fantastic, lots of wildflowers, waterfalls, and soooo green.

Went March 31, 2018. Beautiful hike, even without waterfalls, but glad they were there! Spring seems like it might be the best time to go. It’s not hot yet, the waterfalls are going (if we have rain), and there’s a ton of wild flowers! Saw some turkeys, butterflies and heard frogs. Great spring hike. Everything was green. Great views of city below too!

Beautiful hike! Loved seeing the waterfalls. We went in March and it was muddy most of the way but still lovely. We went clockwise and there was lots of steep uphill spots. Would like to do it again. Round trip from street to loop and back was almost 7.5 miles.

very beautful

Visited on a sunny Sunday afternoon. It's a wonderful hike with multiple tiny waterfalls on the way. We did the loop anti-clockwise and found it to be moderately challenging. There are certainly a few sections of steep climbing, but nothing very strenuous. If you're visiting Mt. Diablo park, this should definitely be on your list of hikes!

Love it! Basically it’s Cardinet Oaks Road all the way (approx 30 mins) to the point where you can turn either left or right for the loop itself. I suggest going clockwise. The Falls Trail is my favorite.. then the second - and last part - of the loop, Middle Trail, can be challenging for some. Can be muddy!

Great views and you just feel like you are in the wide open with no one around.

Great views all around! The first mile makes for an awesome workout...nothing but climbing!! Would love to live close to some climbs like this so I can do repeats as my evening workouts.
My party followed this route up to the summit then north peak. From there we went on the trail for the Grand Loop Trail.

Good hike with awesome views.

Southern and eastern aspects of loop are quite exposed. Late January and I found myself wishing for a pair of shorts and a T-shirt. That is, until coming down into the valley of the northern and western aspect of the loop (I journeyed counter clockwise) which is shady from the oaks, full of moths and birdsong, and has a few creeks running across. More muddy than I expected and finished within two hours at a strong pace.

Awesome views of the mountains and of Clayton from a high altitude. Definitely worth the 30-45 min. drive it was an awesome activity on a beautiful Saturday afternoon!

Great hike! Great cardio! The first hour or so is just up up up. So if you’re not a regular hiker this will feel more like an extreme or strenuous hike instead of moderate. Great views! BBQ trail very nice and wooded. We have seen baby bob cats. Haven’t seen the mothers so be aware. Lots of mtn bikers. They go fast so just be looking ahead. Everyone is very respectful. Usually takes us 2:40 minutes to do.

awesome views

Awesome hike with my family! We weren’t expecting steep uphill and downhill segments but that made it all the more satisfying. There are a few points where the trail has been repaved for ease but we took the normal parts which added an extra taste of adventure!

It was an amazing hike with some great elevation. Decided to turn it into a trail run and did a 15k. Would def go back and explore more with more time to spare.

Great hike!

It was great hike with great views of Bay Area and part of Central Valley. Sunset from eagle peak was awesome.

Very lovely climbs, views and paths except for Falls Trail . That trail is hard scramble and seems to disappear over boulders. Use this trail with a GPS app to stay oriented!

Moderate short hike to experience the North face Mt. Diablo fire recovery. Old flood control dams are interesting to see, but during the wet season this hike might be challenging due to high creek flows.
