We love staying here when the weather is cool. In hot weather without hookup, it's just not fesible unless you really like heat. Even though we're self contained with a generator, the limited time to run it stops us from staying when it's in the 80s at night.
Clean, well kept campground. Some of the spaces cannot be reserved so there is a good chance you can drive in and get a spot if not too late in the afternoon. Lots of shade trees. There is both a pump out and water at the campground entrance. Nice restrooms. Park rangers give talks Fri-Sun evenings. Very interesting. Gorgeous park. Lots of great trails. We'll be back.
We stayed here one night in a 27 ft trailer- it was very warm during the day but chilly at night (in the 40 s) as it was September. Park is quite - some sites longer than others. Primitive camping very dark at night sky was beautiful. About an hour from the interstate.
