I brought my dog up there yesterday. We car camped overnight without any issues. Only saw a couple of cars, and one group camped 3/4 mile from me. I had a lovely time checking out the bouldering and climbing. While there we couldn't find a clean or easy route to the top of the hill, it made for an interesting charge over loose impediments and various cliff bands. If you go this route, I recommend hiking boots and a pretty good level of mountaineering ability as you could potentially slip or get in a tough cliff band.
Only bummer is that there is no burn season right now (mid-August), so we just enjoyed the night sky.
