If you are visiting a park with kids, the junior ranger program lets them finish an activity booklet, show a ranger their answers and earn an official badge. Rules vary by park, so check before you go.

How the junior ranger program works
The program’s motto is “Explore. Learn. Protect.” Children take an oath to protect parks, keep learning about them and share their own ranger story with friends and family, according to the Jimmy Carter National Historical Park page.
Interested youth complete a series of activities during a park visit, share their answers with a ranger and receive an official badge. The exact steps differ from park to park, but most follow the same pattern:
- Ask for a booklet at a visitor center or ranger station.
- Work through the activities as you explore the park.
- Show the finished booklet to a ranger.
- Say the pledge with the ranger and collect your badge.
The NPS says its programs range from simple scavenger hunts for younger children to multi-day ranger-led activities. As of that Junior Paleontologist page, updated October 2024, over 200 NPS areas have a Junior Ranger program.
Who can be a junior ranger?
Almost anyone can join, but each park describes its audience a little differently. Here is how a few of them put it:
- Jimmy Carter National Historical Park: junior rangers are typically 7 to 13, and the park says there is no age limit, according to its page.
- Joshua Tree National Park: typically 5 to 13, though people of all ages are welcome, says the park.
- Booker T. Washington National Monument: the steps are written for visitors between 6 and 12, according to the monument.
- Crater Lake National Park: ages 6 to 12, “or a kid at heart”, per the park’s July 2026 page.
In short, treat the age range as a guide rather than a gate. If an adult wants a badge too, the Jimmy Carter page says you are never too old.
What the booklet asks for at different parks
Every booklet is built around its own park, so the tasks change. Expect a mix of drawing, writing, observing wildlife and attending a ranger program, which is how Joshua Tree describes its activities.
The number of pages you must finish also differs. A few examples show the range:
- Crater Lake: complete at least 7 pages of the activity book, which is free of charge in the park, as of the July 2026 page.
- Dinosaur National Monument: try to complete as many pages as your age, so a 10-year-old aims for at least 10 pages, says the monument.
- Wind Cave National Park: start with the Learn with a Ranger activity on the first page, then pick any other activities you like, according to the park.
At Wind Cave, the ranger activity can be a cave tour, a campfire program or the park film. Some parks also offer special add-ons, such as the Junior Ranger Night Explorer program at Joshua Tree.
Younger children and pre-readers
Many parks print more than one booklet. Glacier National Park offers reader and pre-reader versions at visitor centers and ranger stations, and its ranger programs welcome kids who are accompanied by an adult.
The Dinosaur National Monument pre-reader book is designed for ages 5 and below. Ask at the desk which version fits your child, because a booklet that is too hard is the quickest way to lose their interest.
Earning a badge from home or by mail
You cannot always visit in person, and the rules for remote participation vary. Check the park’s own page, since policies change.
- Jimmy Carter National Historical Park: if you cannot reach the visitor center, the park can mail a badge after you send pictures of your pages and a mailing address, per its page updated July 2025.
- Crater Lake: email a scanned or photographed copy of your finished book, or watch videos at home and print badges, as of the July 2026 page.
- Dinosaur National Monument: email the park, wait for a ranger reply, attach photos of the finished book and receive a sticker by mail, as of the September 2026 page.
- Joshua Tree: the park says it cannot mail booklets or badges, as of its July 2025 page.
The Junior Paleontologist booklet is another route. The NPS wrote in November 2024 that it was again able to accept booklets by mail, as shown on the Junior Paleontologist page.
Tips for a smoother visit
A little preparation helps kids finish. Several parks let you download the booklet first, so your child can get a jump-start at home, as Crater Lake suggests.
- Check the park calendar before you arrive, since Dinosaur National Monument offers ranger programs in summer that can help kids answer booklet questions.
- Ask staff for a pencil if you do not have one, as the Jimmy Carter page suggests.
- Let your child choose the activities when the booklet allows it.
- Keep a spare half hour near the end for the ranger and the pledge.
If you are still choosing a destination, the best national parks for beginner hikers are a gentle place to start. Read the basics of national park wildlife safety before you head out on trails together.
