Caves may not be the first thing that come to mind when you think of Iowa. However, the state has several interesting caves and cave systems. Whether you are looking for a laidback cruise through an underwater cave where the boat does all of the work, or a true spelunking challenge for an experienced caver, Iowa has something to offer everyone. The caves can also be a great way to cool off on a warm summer day as most of them are pleasantly chilly inside. Several of the caves even have ice formations for much of the year, which is quite a neat thing to experience.
