I truly enjoyed this beautiful place. We parked off of Frederickson in the parking area. There are no restrooms here, just a heads up. Ascending the Stewartville Trail, then winding left onto the Star Mine Trail at the camp area, you'll walk through the camp parking lot to continue. We went even further to the Oil Canyon Trail at Star Mine's end, to the upper Overlook, which is a fairly steep incline. It was lovely up there with a valley/delta view, but wires (and electrical noises) disrupt the view and sounds. Coming down, we hit the Stewartville Trail back, stopped to add Prospect Tunnel to our hike (+1.5 mi), then back to the parking area. The tunnel is great, you can walk inside, but I recommend a flashlight. There's a great variety of wildlife present throughout the preserve. Today, we spotted two coyotes from a pretty close distance at the summit of Star Mine.
From the parking lot and back, with all of the above, we timed at 4 hours exactly.

In my opinion, this is the best trail in Black Diamond Mines. It has a camp ground, a mine, a canyon, trees, a huge sand stone wall (natural amphitheater), a pretty intense climb up sand stone and when you get to the top it has a beautiful view with a bench! 5 stars!
