Honestly, this is in my top few favorite parks in the East Bay. It is quiet, clean, and the rangers are very helpful. I think I have been visiting here for close to 25 years, and it has improved so much over that time. Absolutely love it.

Really nice and very clean!! EBRPD staff were SUPER NICE and very helpful. Lots of parking, picnic tables in the shade, very clean restrooms and well managed trails. Looking forward to more trips here.

Beautiful green rolling hills during springtime. Literally a Microsoft wallpaper, but in real life! Kiosk was closed when I visited, according to website they’re “seasonally open” so not sure when they start collecting fees. Took advantage of that fact and we enjoyed an amazing hike with views of Mt Diablo, the delta, and surrounding hills. Beautiful wildflowers everywhere! Dog friendly as well, our dogs enjoyed the hike off leash.

Had a great time at this trail. Overall it’s not a very exciting and picturesque trail. No stream and not much trees. Round valley is a better trail.

Thanks! Your review is awaiting moderation.

Can we bring dogs?

Miya Yi | Aug 29, 2019
Michael Londerville | Aug 28, 2020

Yes. They will ask if you have dogs, but it is allowed. I believe there is an extra fee, and they will give you the "speech" about wildlife, leashes and cleaning up after your dog

Are people allowed to film here? I have a school project where we need to film and there is a building here we think would be perfect.

As of 12 - 22 - 2020 Black Diamond regional preserve is open however; the mine, Greet house visitor center and Sydney flats visitor center are closed and Will remain closed until further notice. That means that mine tours are canceled for the forseeable future.

Can I bring a 2 year old to the park and tour?

Sam | Aug 29, 2019
Jeff Silva | Aug 29, 2019

Any age is welcome in the park. To go in the mines you have to be 7 or older. Just be cautious in the summer months as it gets extremely hot.

How many miles of hiking trails, and does it go to the summit of Diablo. . .? Thank You.

Ted Graves | Aug 29, 2018
Steve Kissinger | Aug 29, 2018

I've been parking there for years with no issues. The park service goes by the lot regularly since its the same road for them to use to access the mines.
