Crystal Cave
Kutztown, PA, 54°F inside, from $21
An all-water limestone cavern in central Pennsylvania toured entirely by boat, at a constant 52°F, with a separate farm and wildlife bus tour.
Centuries ago, the Seneca Indians discovered this natural landmark in the Valley of Karoondinha (Penn's Valley). Local history tells of Indians and early explorers using the dry rooms for shelter. In 1885, Penn's Cave opened as a commercial show cavern, and the Penn's Cave Hotel was built. In 1978, Penn's Cave and the Penn's Cave House were placed on the National Register of Historic Places.
