Natural Bridge State Park

Day-use park with a breathtaking natural sandstone arch created by the eroding effects of wind and water. Natural Bridge and Rockshelter State Natural Area is located within Natural Bridge State Park. Natural Bridge and Rockshelter contains the largest natural bridge known in Wisconsin, created by wind erosion and weathering of the sandstone. The arch measures 25 feet in width and 15 feet in height on its inside dimensions. The top is 35 feet above ground level. At the base of the sandstone bridge is a rockshelter 60 feet wide and 30 feet deep. A partial excavation at the site revealed Woodfordian and Archaic inhabitant artifacts with earliest estimates of human occupation between 9000 and 8000 B.C.
