The East Bay Regional Park District began acquiring land for Black Diamond Mines Regional Preserve in the early 1970s. Today, most of the mining district is within the Preserve's nearly 6,096 acres. The area is an ideal location for hiking, picnicking and nature study. Naturalists conduct a variety of programs relating the Preserve's natural and historic resources.

Great trail, very scenic, definitely challenging. There is very little sun cover, so bring plenty of water and sun protection. When you get to the first fork, go straight instead of up the giant hill on the left, you have enough of a challenge later. Enjoy the views and the natural beauty because it is quite something out there. Be sure to keep an eye out for the ridge trail to loop you back to the cars (if you strictly follow the Stewartville trail signs, you will find yourself on a not so scenic 1.6 mile detour that is not worth it). Please note, that the ridge trail is definitely the challenging part of the "loop", so save some energy and water for it. Also be warned, if you're planning on bringing your dog, keep him/her on leash as we did encounter a rattlesnake today (this also being the reason for docking one star). Overall, we had a great adventure but were slightly unprepared. Enjoy!
