Oklahoma campground is mainly a pleasant overflow area if you can't find a site at the slightly more scenic Panther Creek campground down the road. Clear and flat, Oklahoma was named for where an influx of settlers were coming from in the late 1900s. The nice features are ease of use, being next to a wonderfully wild little stream and under great tree cover. Hiking and exploration are amazing within the Gifford Pinchot National Forest area, so you're within a prime natural space here.
