From the North. Head west on County K from Highway 57 until you come to County C and turn right. Then take your first left on County N. You will pass over Sugar Creek and the parking lot is on the right.
From the South, Take County N north of of Highway 57 until it turns east and the park is immediately on your left.
Update: Played the course on 11/4/15 and there is now a bridge across the creek connecting the parking lot to the beginning of the course. No need to walk down County N.
