Many of you have been asking if there are age limits for the "Journey to the Center of the Earth". Yes there is an age limit. You must be age 10 or over to go inside the mine. There are activities for younger kids on the surface; however, at least one adult will need to stay with them while others in the family take the tour. Tours begin at 5AM and the last tour leaves at 2:30PM. Keep in mind, last year the last person in line that made the tour at 2:30PM was in line at 10AM. So, come early and be prepared to wait awhile. There are displays for you to check out while you are in line. Thank you and we'll see you there! Take the 13th Street exit off I-35 in Ames, go west to Dayton, turn north on Dayton and follow the signs. There will be people directing you where to park. Please wear closed-toe shoes.
