Be A Junior Ranger

Jewel Cave has two Junior Ranger Programs. One is for children ages 5-8, and the other is for children ages 9-12. Completion of the program requires you to take a cave tour, plus spend between 30 minutes to one hour completing the activity booklet. You will earn a badge after you complete the program. Ask for a Junior Ranger Program booklet when you visit. There is no charge for this activity.
