This is a COE (actually Birch Lake at Barnsdall) lake and campground that is fine for smaller (lower) towables and Class C's. Not particularly big rig friendly. The trees are NOT trimmed back & up sufficiently avoid with a larger Class A (rough on paint finishes.)
We tried 3 different pad sites that were long enough for or 40 ft DP BUT were very difficult to level safely.
We left the park and drove over to COE Skiatook Lake Twin Points campground (about halfway between Skiatook and Hominy, OK) for a nice lakeside pull thru with 50 amp service!
