Welcome to Jewel Cave National Monument. The monument is home to the third longest cave in the world. A visit to Jewel Cave National Monument is most enjoyable when it is pre-planned. We suggest you begin by deciding which cave tour is appropriate for you and your family. All cave tours are ranger-guided. There are four tour options during the summer season. All cave tours provide a view of two types of calcite crystals known as nailhead spar and dogtooth spar, which are the 'jewels' of Jewel Cave.
