The front entrance to the caverns and gift shop. At $10.95 per adult ticket, I found this to be a very good deal. The trip is about 45 minutes long and an easy 1/3 mile hike through the walking tour part of the caverns. There is another 5 miles of on your belly- through the mud caverns that can be done on Saturdays or by prior arrangement. One can even camp overnight in the caverns if one is so disposed.
