This made a great base to explore the park. The lower designated sites were crowded (often with more than one camper by site). I drove up a little further up and enjoyed lots of solitude. Some of the sites are walk-up: you park here the yellow sign is and hike a couple of minutes to the actual designates site (if you have a tent). IMHO these were the best: best views, solituded and even signal! Downside: you can't see the tent from the sign so I got back from hikes and the spot to park the car was filled. As someone else said: the vault toilet is at the entrance. There isn't one as far as I drove up. The road varies in quality: some parts are very smooth, some parts are very rocky (so parts looked very muddy after rain!). There were some bugs/mosquitos but not too crazy.
