DOOR COUNTY, WISCONSIN - Located in the 19-acre Cave Point County Park, this iconic carved rock was formed by the crashing waves - reaching as high as 30 feet - from Lake Michigan beating the shore and dissolving the limestone. Kayakers and scuba divers are able to explore the dozens of underwater caverns hidden from view. The park offers hiking trails, picnic areas and scenic views of beaches and Lake Michigan.
