Would you like to explore the National Parks and earn cool badges along the way? The Junior Ranger Program is a fun and free way to learn about your national parks. Stop by any of our information centers to pick up a Junior Ranger booklet or download (3.97MB PDF) and print a copy before leaving home. Complete the activities at your own pace while exploring the Mojave Desert. Once you're finished, return to one of our information centers to take the Junior Ranger pledge and get your badge.
