This place is fantastic and, from what I have seen, empty of people. I recommend getting a hiking book if you plan to explore this place for a couple days. There are not many marked trails in the preserve so you have to hike cross country which can be very tricky. I got off track by miles a couple of times. I do recommend the Mid Hills trail, which is well marked. Mid Hills is also an awesome place to camp.
My boyfriend and I camped out here for a night in December 2011. It was freezing cold at night, but it was very secluded. They had free campsites that you can drive to and pre-made fire pits in the camping spots. It was a nice little get-a-way for the night. We were going to hike to the mines (which was a couple miles near our camping site), but we decided to head home. They do have this old area where they used to herd cattle (I'm assuming). It was pretty cool! I definitely wouldn't mind going back there!
