RV Sites in Tulsa OK south or Broken Arrow

Don't know anything about RV parks there but I used to live on Mingo rd. at Admiral when I attended Spartan School of Aeronautics. Us guys used to frequent Bells Amusement Park near the Expo center on Friday nights. Good memories.

Depending on what you want, the Expo Square "parking lot" could work. I stay there for a week every January for the "Chili Bowl" indoor midget car races. Good facilities. But if you're looking for green grass next to a creek, that ain't it.
Call first to be sure there isn't a horse show or similar.

The south part of Tulsa is upscale, so no RV parks. Mingo RV park in north Tulsa usually has a place or two for travelers. (Like many urban RV parks, it is mostly occupied by permanent residents.) We have stayed there a few times. The location is Mingo & I-244. Tulsa's road system is pretty fast -- it wouldn't take long to drive to south Tulsa.

Keystone State Park to the west is about twenty minutes from downtown and would be a nice place to stay.

I believe there is a Corps of Engineers cg a few miles east of Broken Arrow. "Bluff Landing." Just a few miles out of town, a straight shot on (45mph) 71st St. I’ve never been there though (too close to home to consider camping there, I guess). Anything else close by that I can think of is more of a ‘parking lot’ atmosphere. There’s a place like that at the Tulsa fairgrounds, on the pavement, "Expo Square."
