The Blue River is beautiful. The camping is free but you must have an Oklahoma fishing license rather your fishing or not to camp there. There is around 80 campsites nestled in the woods along the bank of this beautiful clear river. It is primitive camping. There is no electric, water faucets, picnic tables, or grills. The bathrooms are primitive as in no flushing toilets. No showers. Hiking is great but watch out for snakes on the ground along trails. I saw a few. There are many snakes such as rattlesnakes and copperheads. I havent saw water moccasins maybe because the water is too cold.
