real nice find! Crab Orchard is a pretty big place, with four campgrounds. The other campgrounds have full hookups for the big boys and cost more. But E Loop is the oldest and has become the bastard stepchild in the corner. Electric only inside the loop, no hookups outside. Its bathroom is kinda gross, but hey, $5 for overnight and a shower ain't bad.
Turned out to be a delightful stop! A large grassy area in the back corner of the fairgrounds. $10 for hookups, $5 without. A one person bathroom with a shower. Perfect with on one else here, probably less so if it were busy.
Oh, this place is soooo nice! It is now the same management as Miracle Hot Springs, so for your $10 ($8 for senior) you can go to both. Camping over here is both cheaper and way nicer. The Miracle soaking setup is way better (see their Spot entry), so driving to Miracle for your soak and staying here the rest of the time is the best bet. Banbury is a very large concrete pool, with very hot water coming out one place and cold water as many other places as needed. It is next to the river. No wifi.
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!
