This is a Kansas State Park, there is a daily parking fee and overnight camping fee.
The Red Loop has two sections: close to the lake and in the pasture. Close to the lake is very rocky and challenging where the pasture is easy running. The overlook of the lake along the far south end of the Red Loop is very pretty and the run there is totally worth it!
The trees are well marked with red paint. Use the map or follow the red painted on the trees.
