We stayed at buzzards roost overnight which is the best site for backcountry camping IMO. We had a fantastic view of the rock and the horizon from our site. There was only one other group of campers out at our site which was'nt bad. If you are looking for isolation however this is not a park for it. There are herds of people hiking up the rock during the day. We did not follow many of the trails and explored the area off trail mostly. We spent most of our second day climbing up the rocks from the least traveled areas which was very challenging. This is a great place to go if you want a challenging climb (for an average hiker). You can make it as hard as you want, although we chose a rather easy route that was challenging enough for us. Its a small park and all most if not all can be seen in a full day. Definately worth checking out.
