Established on February 7, 1908, as a National Monument. Jewel Cave stretches across an area of around 1,273 acres making it the third longest cave in the United States. With over 180 miles of charted and plotted passages, this underground wilderness charms to human curiosity. Its impressiveness is revealed through fragile formations and previews of brilliant color. Its intricacy of passages tempt explorers, and its scientific wealth remains a mystery. This resource is truly a jewel in the National Park Service.

Frank and Albert Michaud, two local prospectors, noticed the cave in 1900, when they felt a cold breeze blowing out of a small pit in a canyon. It is undetermined whether any previous occupants of the area were aware of the natural cave opening, which was not sizeable enough for a person to enter.

After enlarging the cave entrance with a controlled blast, the Michaud’s found a deep cavern lined with calcite crystals, which steered them to name it "Jewel Cave."

President Theodore Roosevelt pronounced Jewel Cave a National Monument on February 7, 1908.

The Park Service offers three tours: the scenic tour, a half-mile loop through a cemented and lighted central portion of the cave accessible by elevator; the historic tour, a candlelight tour through the earliest-discovered part of the cave; and a wild caving tour, through an immature part of the cave near the scenic loop. There are 3 surface trails varying in distance and difficulty.

The ability to view wildlife is plentiful at Jewel Cave National Monument. Most live in the forest and open meadows of the surface but some also live in the cave itself.
