What a great place! Walk over to the golf course clubhouse to check in, she gives you the wifi password, then you pretty much park on the grass anywhere you want. The wifi was great, it happened that I parked 30' from the bathrooms What with food at the clubhouse, good wifi, and a short walk to the shower, I literally could live here a while.
The park is pretty cool. It's an easy walk from the campground to the little waterfall, and the boardwalk makes some quite dramatic bridges over the chasm. Yes there is a chasm! Oklahoma State Parks did a very nice job with this. And across the chasm is a frisbee golf course!
Disneyland for adults! many bars, three restaurants, weekend concerts, historical buildings, free coffee, beautiful grounds, and warm soaking pools with groovy little shower thingies and complementary bathrobes. deee-LUX! There are men's and women's dorms at opposite ends of the third floor, so one can stay relatively cheaply.
