Black Diamond Mines

Review: Went by here on the way home. Nothing but fire road and posted no bikes on single track. In fact no bikes on roads smaller than 8 feet shoulder to shoulder. Don't bother. BTW Lime Ridge is same, videos of riders there are on illegal trails. Lime Ridge is close by.

Review: Really can't think of a reason to ride this place unless you live close by and don't want to drive. Steep, boring fire roads and it bakes in the sumer...nuff said.

Review: The trails here are all fire trails. It is the second hardest trail after Mitchel Canyon/North Ridge around Diablo mountain, in the Antioch/Walnut Creek areas. None of the trails are technical, but the hills are steep, sandy and loose soils. Because of this, I have marked this as extremely difficult. If you dare to go up the North Ridge, you will go up the steep hill continuously for about 3 miles to the very top. Guarantee that you will have an aerobic workout. If you want to train for endurance this is the place.

Review: HOT, dry, bumpy, miserable and close to my heart. I grew up here, and I still take my kids hiking here. Tried to take them riding here but it was much too difficult for them. I now Ride the entry road for training as often as I can since I live near by. The stuartville trail is a real a$$ kicker.

Review: Rode this trail this wkend. I'd HAVE to say, S***ED. Nothing but fire trails that are endlessly uphill, then down into canyons. Everywhere you turned to look, the signs said NO BIKES. WWon't go there again.

Review: If you attempt this trail, bring plenty of water. Once you drop down into the canyon, you have no wind and hight temps. Its stifling and you will sweat a lot.
