Yellowstone National Park has a self-guided, Junior Ranger program for visitors aged 4 years and up. The Junior Ranger program is a way to introduce children—and those young at heart—to the natural wonders of the park and their own role in preserving these wonders for the future. Full-color booklets are available at visitor centers in the park for $3 and a Junior Ranger patch is awarded to those who complete the requirements.
To become a Junior Ranger, families may request the $3 Junior Ranger book at any visitor center in Yellowstone. After completing the age appropriate requirements described inside the booklet and reviewing their work with a ranger at any visitor center, participants are awarded an official Yellowstone Junior Ranger patch. Modeled after the National Park Service patch, Junior Ranger patches are shaped like an arrowhead and feature a geyser for 4-7 year olds, a grizzly bear for 8-12 year olds, and a bison for those aged 13 to 113 years.
