Biking on the refuge is a wonderful way to view wildlife and just enjoy the outdoors. Bicyclist can travel on all roads and dikes throughout the refuge unless marked closed. A portion of the Great River State Trail (GRST) passes through the refuge which makes a great connector for those coming from Perrot State Park on a leisurely bike ride or for the serious cyclists using the GRST. Trail passes for the GRST are sold at the refuge (but are not needed for biking in the refuge).
