Steep switchbacks up to the campground.  The campground has private residences dispersed throughout.  The outlay of the park is somewhat confusing.  Be sure to study a map well.  The campground is almost immediately to the right as you get to the top, but you have to go past that quite a ways to the visitor's center to check in.  The views are amazing, but it is windy being at the top of the mountain.  There are cabins but I stayed at a campsite (#14) with a view.  The bathroom facilities near the campground are a bit of a walk from the campground.  If you have your own potty tent, you may consider bringing it.  My site was not level so I used leveling blocks.  I have my Jeep outfitted for sleeping in.  The more interior sites looked to be more level. No big rigs are allowed up the mountain, I think nothing longer than 24'.  I did not take any of the hiking trails, so I can't comment on those.  My old dog just can't do too much hiking anymore.  Staff were friendly.  The electricity worked great, but the water spigot was barely functional.  Bathroom was kept clean and had one shower with typical camp wall spigot.  The road down the mountain leads into a small, industrial type town.  Walmart, Dollar General is nearby as well as many typical restaurants.  I utilize a WeBoost, and a hotspot on my iPhone. I was able to stream shows without much buffering.  I got anywhere from 1-4 bars on ATT LTE.
