While becoming a junior ranger, you can learn more about South Florida's four National Parks, Everglades National Park, Biscayne National Park, Dry Tortugas National Park and Big Cypress National Preserve, their different habitats and why each park is a unique and special place.
Ask for a Junior Ranger booklet at any visitor center, and complete the section for the park you're visiting. When you're finished with the pages for a specific park, stamp the inside of the back cover with the stamp found in the park's visitor center. Tell the Park Ranger you have finished the pages for that park to receive a Junior Ranger badge.
If you collect badges from 3 or all of the different South Florida National parks, you can send a copy of the stamped booklet page to the address provided and you will receive a neat patch.
