Jewel Cave National Monument
Custer, SD, 49°F inside, from $16
A national park cave known for its boxwork formations, seen only on ranger-guided tours that start at the visitor center.
In 1881 Tom and Jesse Bingham heard wind blowing out of a small hole while riding up a draw; Charlie Crary is believed to be the first person to go down into the cave, and Frank Herbert wrote the first known account of a trip inside that year. A 1959 National Speleological Society expedition mapped about 3 miles, and cavers have kept extending it since, adding around 7 miles a year since 1999.
