Wichita Wildlife Refuge, OK

This is a GREAT place. They have some really fabulous hiking areas, my favorite is the Elk Mountain hike - it's not that high and you get a spectacular view. They do an Eagle/Hawk tour in the late winter and they take you into private parts of the park. Another good trail is the Charon's Garden Trail. There's a great trail map on their site. Mt. Scott is a fav among mt. climbers and repellers.

Also Quartz Mountain State Park is close by which is a beauty of a facility. During the summer they have arts camps there for kids who qualify in high school, so the facilities are really fabulous.
