We waited until 1:30 PM to enter the caverns. There are 96 Grade 2 kids here for tours in the morning and the 1:30 PM was the first childless tour.
The tour has 160 steps and goes down 155 feet (47 m). The total distance in the cave is 2 miles (3 KM) with a temperature of 70 F (21 C) and 98% humidity.
The tour was great! We enjoyed the day.
