Squire Boone Caverns were discovered in 1790 by Squire Boone, a prominent explorer. You can explore this wondrous cave yourself centuries later as you wind down the spiral staircase that opens up to waterfalls, streams, and some pretty amazing rock formations, some of which are nearly 40 million years old. This park consists of a one-hour walking tour into the caverns, as well as a working pioneer village and grist mill where you can feed farm animals.
