Natural Bridge State Park was established in 1973. It totals about 530 acres, including a 60-acre scientific area. The main attraction of the park is the large sandstone arch or “bridge”. The top of the arch stands about 35 feet tall. The opening in the bridge is 25 feet high by 35 feet wide. The formation, which is similar to those seen out west at Arches National Park in Utah, survived the last ice age in Wisconsin’s Driftless Area. However, unlike the arches out west, this one is hidden in a thick forest cover. Directly under the bridge is a rock shelter used by native people over 10,000 years ago. Most references today call this the Raddatz rock shelter after a family who owned the land before it became a park.
Natural Bridge State Park is open for day use only. There is a small picnic area and the trails have not been maintained as shown in the official map. Camping is not allowed in the park. The park is not staffed.
