Two days ago I hiked the Miner's Ridge Loop at Black Mountain Open Space Park. I really like this trail. It took me approximately an hour to hike the loop. There is quite a bit of uphill climbing on this one, especially on the first half. The second half is mostly downhill. This particular day I didn't see a single other person from the time I parked to the time I left. Parking is free. Here are some pictures from the park:
