Robber Baron Cave Open House
Saturday, November 11, 2017

At this year’s Robber Baron Open House, we are offering advance reservations for the regular self-guided tour, for those with limited time who want to skip the line, and a special off-trail guided tour to parts of the cave not visited on the regular tour. In both cases, the number of advance spaces are limited and reservations must be made through the link below at

No reservations are required if you just want to show up and explore the cave on the regular self-guided tour as usual! 

If you sign up in advance for these tours, please arrive 10 min before the scheduled time in order to get geared up as the tour will leave shortly after the listed time. If you miss the time, you can still visit the cave through the regular sign-in process.
