Two Caves Not One

There are two caves in Colossal Cave Park. Colossal Cave is open to visitors. Arkenstone Cave is a “live cave” and not open to the public. The “live cave” designation means the cave continues to grow formations. Only research scientist have access to the Arkenstone cave.

Its estimated that Colossal Cave has about 39 miles of cave tunnels. But only 2 miles of tunnels explored and mapped. The 2 miles of tunnels open to visitor tours drop over 6 stories into the Cave.

Colossal Cave contains with stalagmites, stalactites and large columns. Formed by ground water seeping through the limestone ceilings of the cave to create them. As water flowed over millions of years mineral deposits in the water bond together.

When the water evaporates, mineral deposits bond to create the stalactites and stalagmites. Columns are formed by the union of a stalagmite and a stalactite.

Temperatures inside the Colossal Cave average 70 degrees (F) throughout the year. Even in the summer when outside temperatures are in the low 100’s.
