The Upper Mississippi River National Wildlife and Fish Refuge is the longest, contiguous river refuge in the continental U.S. at 261 miles long. It was established for the preservation of fish, wildlife, plants, and a breeding place for migratory birds. The Ingersoll Wetlands Learning Center sits on 36 acres of sand prairie that is home to the ornate box turtle, prickly pear cactus, and more. It provides family friendly hands-on exhibits that educate and celebrate the Mississippi River. The refuge offers access the Great River Trail and an 8.7 mile gravel path along Spring Lake with two observation decks. Great place for migratory bird watching and eagle watching.
