How late do they run the guided tours?

All tours are guided. Visitors ride through the cave in wagons pulled by a jeep driving tour guide. The hours are 8AM until 7PM. Easter hours may vary.

When we went, they took us on the last tour that day, which was 4:25 pm. We got out just in time to pay for our gift shop items. The employees were walking out behind us. This was three weeks ago, so they may have longer hours now, due to the season change. They run tours every 25 minutes.

Till 7

I Think the last tour starts at 5:30 or 6:00 pm

6or 6:30
