The description states:

CAVE POINT, SOUTH OF JACKSONPORT
Door County, Wisconsin
—Cave Point Park is a popular tourist destination for travelers from many states, but is sometimes overlooked as it is a county park and not a state or national park. The eroded limestone shoreline gives the place it’s name.
