Even in the light rain, the trail was fine. This place is amazing!

Great views and a fairly easy hike. Total mileage count was about 4.75 after parking, which is a nightmare since there is no good spot to park with out risk of a ticket. The first half is up hill but worth the the hike. It was a phenomenal view and the kids enjoyed climbing the rocks. Bugs and flies through out the hike near the water was heavy at times. Watch out for the mountain bikes.

Great hike. Amazing views. Starts out slow and then you hit the incline hard

Firstly, there are a ton of people on this trail because a road goes through the park with turnouts and picnic tables. There are a billion trails through the park so you have to keep consulting your phone to make sure you’re still on the trail. The trail crosses the road at least 5x. Disappointing overall because this isn’t nature and you won’t see much wildlife with this many people and cars. This is my first and last visit to Mt Diablo.

Great trail, not too muddy, flowers are barely sprouting. Rock city was AMAZING would definitely recommend climbing sentinel rock! I would rate this moderate. Bring proper shoes!

This was a good hike. I enjoyed it a lot. Unfortunately, we went after the rain so a section was very muddy and hard to get up. We also went early in the morning around 9. other than that it was a fun trail to the top. Definitely watch out for cars because we had to go through 3 different roads and there are no crosswalking signs. Lastly, we had to park more into the mountain because there wasn't parking at point on the map. It reduced maybe 2 miles.

Such a beautiful trail - nice mix of dense oak woodland and exposed ridges with beautiful views of the surrounding hills and Mount Diablo. Some stretches are very muddy at the moment; it's possible to avoid getting wet, but it'll likely be more pleasant in a couple weeks. Saw cougar scat and boar tracks, so be wary.

muddy after weeks of rain, but what do you expect. beautiful views and little creeks that ran throughout. went through two water bottles not very hard trail.

Alltrails leads you to Regency Drive to access via Regency gate. DONT GO THERE. It is a congested traffic nightmare. Regency is a dead end street with limited parking spaces so it is extremely difficult to get out of there. Plus there are no bathrooms, water, trashcans etc. Mitchell Canyon is the preferred way to start your hike. Beautiful spacious area. Plentiful parking, clean restrooms, water, trashcans, picnic area as well as ranger station with trail maps. Much more enjoyable experience from Mitchell vs the congestion at Regency. Make a day of it and enjoy Mitchell's picnic area.

Great hike. Amazing views. Elevation change can be a bit strenuous but totally worth it. I also really enjoyed going through the welcome center at the summit.

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

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!

Beautiful

Trail ends 2 miles in, private property

Great sweeping views, really awesome! We hiked counter clockwise. I recommend hiking sticks as many parts of trail are steep with loose rock. There was a lot of poison oak, sometimes very close to the trail. Take water! We started hiking at about 830am. Good to start early. Road to Juniper has lots of bikes and traffic. $10 per car fee at gate.

Counterclockwise. This was a very difficult trail. Not because of the length or up and downs. Bit because of the “slipperiness” of the trail. The down hills especially had to be traversed with baby steps because if this. And lots of brush overhanging the trails not good for ticks and poison oak. $10 self service to get in. All day never saw a park employee. I will not be back and don’t suggest this trail, not much fun.

Backpacking Day 2 of 3 Mt. Diablo Range. Live Oak Campground (Mt. Diablo) to Morgan Backpack Camp (Morgan Territory).

If heading clockwise, your first 2+ miles are generally downhill. Then the (choose your adjective) begins. 3+ miles up. And on some stretches, it’s very steep, and doesn’t seem to let up. However, the vantage points near the summit are worth the weary legs (and lungs). Enjoy a savory meal and a beverage afterwards. You’ve definitely earned it.

Pretty steep. Trail was washed out after the campground, so take the road to Rock City instead. It's very cool!

I did this hike yesterday. It's pretty tough but the trail is well maintained, there are several (4) toilets along the way, and there's water at the top of the mountain and in one of the campgrounds 1/3 of the way up. This trail is also used by mountain bikers.

Great views from above the fog line. Well maintained trail, half on fire road. Start counter clockwise if you want less steeper climbs.

Sentinel Rock and Rock City are very cool sights to see at the turnaround of this hike. Good trails. Parking is not good at all. There is no parking at all at the trailhead (which is right at the south entrance to the park). There are only a couple spots to park in the neighborhood just below the park

Starting from the Mt. Diablo South Gate entrance near Blackhawk, our group completed most of the full Summit Trail. This trail starts out in the shaded foothills of the mountain, proceeds past Rock City, and continues up the south face of the mount, gradually becoming more exposed, and steeper. The route is mixed between foot trail and fire roads.. Our group was forced to turn back a half mile from the summit, so if you're looking for a challenge definitely recommend. There is no water and only a couple outhouses, so come prepared with snacks and plenty of water.
