1851 Small Wyandotte discovered.
24-MAY-2002 caves under new management.


Wyandotte Caves are two different caves, both developed for visitors. The smaller Little Wyandotte has no long staircases and is thus suitable to visitors of all ages. It was discovered in 1851, and because of this recent discovery it is also called New Cave or Siberts Cave after its discoverer.

More impressive is the tour to Big Wyandotte aka Historic Cave, just 200m away. The entrance of this cave was used as a shelter since prehistoric times.

In the Senate Chamber, 45m long and 17m wide, a stalagmite called Pillar of the Constitution is shown. This is one of several "world's largest stalagmite". Sometimes it is described as the largest pillar stalagmite in a public cave. But if this really is the largest or not, does not really matter: the 10m high and 20m wide stalagmite definitely is very impressive! A highlight is the Rothrock's Grand Cathedral, a huge chamber with the Monument Mountain, an enormous pile of rocks fallen from the ceiling of the cavern. Another feature are rare Explainhelictites in Crater Room.

Unike the Small Wyandotte, this cave has lots of steps and visitors should wear appropriate shoes. It opens later in spring and closes earlier in autumn, as it is home to the endangered Indiana bat (Myotis sodalis) which hibernates in the cave.

The caves were managed by the Indiana Department of Natural Resources until 2001. Since 2002 they are run by a private company under a concession agreement. The first changes so far are the highest entrance fees for show caves we know of and a changed schedule.
