Reservations for the traditional and modified-traditional tours are not needed; but, it is helpful if large groups let us know in advance they are coming.  (See Educational Field Trips – bus and youth groups enter upon arrival.)


Cameras are welcome in the caverns, but please, no video recorders.

Please see the homepage for the days open for this season.  We are open from mid-April through the last Sunday in October.  The traditional Tour and Modified Traditional Tour are offered every day, without exception.  We are even open on holidays.  When the first ticket for the “next tour” is sold a twenty minute countdown is started.  With this rule, no one need wait more than twenty minutes for the one hour tour.  The visitors’ center opens every day at 9:00 AM.  The last tour of the day enters at 4:30 PM.
