Don’t underestimate this hike. Started counterclockwise at 11:30 and ended at 6:15, but was keeping a quick pace and jogging many of the flats/declines. I’m a big guy (6’10 240lb) and I went through 6L of water. Unfortunately, the trail is not very well maintained in some places. You will certainly be ducking under shrubbery and branches sometimes. Also, there are quite a few places where the trail is extremely slippery, so be careful. Poles would probably be nice (I did not have them). If you are trying to do this hike during COVID, all parking is closed in the park. What I did is I parked on a residential street in Clayton near an entrance to the park. Good luck, this hike has beautiful views and is great for training.

Great trail. Lots of variation in terrain. Not crowded at all and great for hiking, mtn biking or running. A little rocky this time of year so be careful when trail running. Some bugs, but nothing out of the ordinary.

Good hike

Had to park off of Regency Drive down the street as no parking signs everywhere. Took the Back Creek Trail up and instead of going straight to Meridian Ridge Road took the 0.6 switchbacks to MRR. Then instead of going up Prospectors as I wasn't too interested in that long hot schlog joined Deer flat Road and only made it to Juniper campground. On the way back followed Mitchell Canyon and almost at the end took Oak Rd to Murchio and back to Back Creek trail. All in all it was 13.4 miles. I would have liked to reach the summit but the heat was getting to me.

Attempted to hike this today 5-23-20 to no avail. COVID has closed the parking lot and all neighborhood parking is by permit only. This area is effectively closed until they reopen the parking lot!

Great views from the tallest peak in the area. Be sure to bring sun protection and watch out for snakes in the summer. Restrooms at the summit with cool war era history to read up on.

Great hike. Main trailheads had parking restrictions so I parked in another neighborhood and made my way back via a fire road along the creek to Donner Trail to go up the waterfall loop. Pretty good climb up after an easy part of the hike up the valley along the creek. Great scenery with wildflowers, birds, and butterflies everywhere. Use some caution near the second and third falls that you can see from a distance. If you go off trail to get a better view of the falls there are a few spots where if you lost your footing you could have a real bad day and go off a cliff into the canyon. Cell reception was pretty good on most of the mountain but would fade out in some spots. Overall a great hike.

11.2 miles. The 6hrs estimate seems off. 4:10 hrs or 5hrs taking stops. Great hike. Recommend trail through time on way down to go through rock city and sentinel rock. Another hiker reported rattle snake. Great conditions today.

We hiked this trail today. Looking for parking was a pain but we finally found a spot. This was a great trail to hike. Quite a few turkeys roaming around. We bumped into a baby rattle snake on our way down. It gets hot quick so I would suggest to start early in the morning.

A little sketchy on the back side of the loop. We went clockwise on the loop so there seemed to be steep spots going down. The sun made the hilltops glow during dusk, beautiful!

Nice hike! Had to find new parking since it looks like most of it is blocked off right now. Nice hike, areas of shade, and a couple tricky areas but beautiful views, and wild flowers. Waterfalls are barely running now, probably will be dried up soon.

Incredible day to hike! It was so beautiful with lots of birds singing, turkey groups hanging out near the creek and even seen a Doe with her youngster! Lots of wildflowers though I’ve identified them all already on prior hikes, at the trailhead I found a new wildflower I have never seen before so what a highlight to the end of my hike!

There are better castle rock trails - this one is too open without shade.

Do not park in residential area where permits are only permitted, parking citations are given constantly. Great Hike to see the summit view of Mount Diablo! Most of the trail is shaded and well kept. Do bring plenty of water, there is a water fountain near the tower at summit if you'd like to refill. Trail has plenty of loose gravel, so trekking sticks will help a lot especially descending. Most of the main flower blooms have already passed, but still a good amount left to enjoy. Happy Hiking!

LP- went a few months ago.... This is one of my favorite hikes.... Worth every drop of sweat!!! Breathtaking views up on the summit. Totally recommend it.

5/16/2020 Hike/Run: This is a great loop that takes you through the southern foothills of Mt. Diablo state park. As far as the parking situation, you can't park at the north end of Finley Rd where the trail starts. You have to park along the road and walk about 3/4 mile to the trail. Another thing is that this loop passes through 1.5 miles of private property. The western fence is at the intersection of the "Jose's World" trail and the eastern fence can be seen if you look for the boundary on the map. I took pictures of both. This section is all fire road and its unlikely that you'll see anyone out there, but if you're not comfortable then take Oyster Point both ways and loop back through Jose's World. The Oyster Point trail is a great single track. The rest of this hike is pretty much all fire roads. You can mountain bike the whole thing. I don't think you're technically allowed to bike on Oyster Point trail, but I saw a half dozen bikers of all ages, so it doesn't seem to be a big deal. I took a side trip to the Jose's World area and there a cool single track there that cuts through a rocky section. Would recommend if you're out that way.

Bring hiking poles, a lot of water, jacket from the wind, sunscreen from the sun. And of course your camera! Enjoy!!!
