Kids ages 6 to 12 can become certified Zion National Park Junior Rangers by taking part in one of two ranger classes at the Nature Center (classes cost $2 per child). Or kids can earn the Junior Ranger badge on their own by completing an activity booklet. The booklet costs $1 and can be picked up at the Visitor Center. Kids ages 7 and older who complete the handbook, which contains questions about the park, will earn a special Explorer Patch. Kids ages 6 and under are also eligible to receive a special patch by completing a free activity sheet, which is also available at the Visitor Center as well as the Human History Museum.
