The River ‘S’ Discovery Auto Tour route is a one-way 4.2-mile loop on graveled road that is open every day to vehicles during daylight hours and changes depending on the season (there is a Fall/Winter Tour and a Summer Tour). An Informative Audio Tour CD is available now at the Visitor’s Station at the entrance to the Discovery Auto Tour Route and also at the refuge headquarters. This CD coordinates with 14 markers set along the Discovery Tour Route. There is no cost for the CD but its return would be appreciated.
