I agree it is in a good area. Yes, it is popular for hiking, biking, horse riding, etc. But you are inside a locked gate. When we camped there, there were only a couple of other campers, and we only saw a horse rider come by.

Yes. The area is popular with locals for hiking, biking, dog walking, etc. We have stayed several times and left our rig without issue. We do bring in our chairs and other outdoor stuff to prevent theft.
