There are two different tours each is about an hour with light to moderate exertion, depending on your activity level, there are many many stairs, lol.
It took us a solid hour for the smaller of tours but was told the extended tour could last up to two hours.
90mins
approx. 60-70 minutes
About an hour
About an hour, but like others said, depends on your group, as well as the group ahead of you. If there are slow individuals, they will slow down the group so that everyone keeps together.
Howdy Susan, it depends on the crowd going, 45min, I had a small group
A little over an hour
1hour and 15 minutes
90 minutes max for each cavern
