This campground is on the base, but so quiet. Within a few miles of the campground is amazing fishing and hiking. Fort Sill is a nice base with everything you may need. If you drive to Witchita Mountain Wildlife Refuge you may see elk, bison, Longhorns and deer. The hiking trails are great and worth the visit.
If you don't have a military ID you can stop at the visitor center and get a pass for your stay
