McGee Creek State Park
McGee Creek is one of my favorite parks. From OKC, it's about a 3.5 hour drive, but it is well worth it. This little park is very quiet and not heavily trafficked. The trails are wonderful, and it's in close proximity to the lake. The beginning of the trails are really well manicured, but as you get into the deeper parts of the trail, they can get a little hairy because they aren't visited often. I've always enjoyed my stay at McGee Creek.
