Spook Cave is a cute attraction – part natural wonder, part campground – in a lovely hollow just over the border in Iowa. The cave itself has few notable natural features, a few stalactites and dripstones. What makes it different the tour is entirely by boat. This is not a tour for the claustrophobic, nor is it for those who cannot bend nearly double at some points. This is a fun little tour worth taking for any cave fans.
