My 9 yr old son wanted to try camping in or near the snow, and the weather was favorable on this December weekend (high 56, low 39). We are pretty new to camping and not hardcore, but this was very easy and comfortable. We camped right at the entrance because nobody was there and there was plenty of flat area. Easily accessible on paved roads. Spotted a rock climber on the nearby rock face when we arrived, who later came by to pick up his car he had parked there.
Caldor Fire damage was evident everywhere, but this made it easy for my son to chop down a small dead tree that we used for firewood. It was breezy, which made it chillier than the temps indicated, but we were fine and very toasty once in our tent cots.
We found a few beer bottles around (which we took home to recycle), and small amounts of building waste such as concrete. But overall the setting was peaceful and beautiful. Amazing to have a resource like this that's free. We brought a privacy shelter and portable camp toilet, and our own water. Those are really the only things you need that would normally be provided by a paid campsite.
