Cave passage.

Mystery Cave

The cave is part of a state park, and map apps will send you to the wrong part of the park. Just follow the road signs.

Pretty neat cave with multiple entrances and different kinds of tours. Ancient ocean fossils are a highlight. Some of the entrances are a drive away from the visitor center, so get your knickknacks before you enter!
