The following post about the Junior Ranger Program is not affiliated with nor does it express the official views of the National Park Service. The quotes from current NPS employees included in the article were shared with approval from the ranger and their national park. 

We tapped into our dear friend and former NPS Ranger and Outdoor Adventure Guide, Grace Lemen for support writing this piece.

From Grace:

Swearing in Junior Rangers was one of the most fun parts of my job as an Interpretive Park Ranger. I could always see the excitement as a group of kids walked to the visitor center desk. Some were shy and would hide behind their parent’s legs as they cautiously placed their completed booklet on the desk. Others would proudly place their booklet in front of me with an enthusiastic, “I’m done!” I always loved looking at the booklets with pretend rigor. After confirming all required sections were complete, I began the official swearing-in ceremony. Some rangers are more casual with swearing-in, but I liked to make it an event. I would ask them, “stand up straight, raise your right hand, and repeat after me”. Sometimes with a nudge from mom, they mirrored my body language, and so began the pledge, “As a Junior Ranger…”

Does any of this sound familiar to you? If not, that’s okay. We are going to break down what the Junior Ranger Program is, why you and your family should participate, and how to get the most out of it.  Combining our personal experience with tips from Grace, who spent three seasons working in the National Park Service (NPS). As a ranger, she learned the ins-and-outs of the National Park Junior Ranger Program beyond the family perspective! While she is no longer a park ranger, she is still an avid advocate of the program as are all members of our family!

What is the Junior Ranger Program?

The Junior Ranger Program is a wonderful initiative by the National Park Service to connect and engage young park visitors–the future stewards of our parks–to their surroundings. Participating parks have Junior Ranger Booklets that include activities and information about the park. Once a booklet is completed, a ranger will look it over for completion. If everything checks out, your kiddo earns a badge or patch.  Some Junior Ranger Programs are National and many are available from your home (more on this below!). Note that while most programs are directed towards children ages 5-13, most parks encourage all ages to participate.

Why Should My Family Participate?


Most research says that the National Park Junior Ranger Program started with the Yosemite Junior Nature School in 1930. Charles A. Harwell, a Park Naturalist at Yosemite, started the program which was filled with questions, activities, and meetings to attend. It wasn’t long before other parks followed suit and the idea of a program became a national conversation within the National Park Service and the Forest Service. In 2005, national standards were set and the program continues to grow and develop today to best engage with the audience. If interested in learning more about the history, The Ranger Archivist has a more in depth post on how the Junior Ranger Program came to be.

How Do I Get Involved?

How to Get a Booklet

Usually you can go to the visitor center for whatever site you are visiting and ask a ranger for the Junior Ranger Booklet. Majority of booklets will be free but some can charge $3. This money usually always goes right back into maintaining the Junior Ranger Program for that site. There are over 200 participating NPS sites with a Junior Ranger Program. If you research the site’s junior ranger program beforehand you can see if there is a downloadable PDF to print off before you even get there! This is often helpful if you are only on site for a day or two because some of the requirements require some time to complete.

Remember that the time of year can affect access to the booklets. Many parks have seasonal closures at their visitor centers. If visiting during the “off-season” for a park (approximately October-March in some areas), call ahead of time to see what your options are for completing the junior ranger program.

What Are The Age Limits?

This one depends on where you go. Typically, a Junior Ranger Booklet will have activities that a child must complete. How many and/or which activities are determined by which age bracket they fall in. For example, a 6 year old has to complete 3 pages and the 12 year old must complete 7. Age brackets might look like 7 and under, 8-10, 11 and up. Some parks have additional programs for those kids who are older but I recommend just doing the traditional booklet if the age limit allows it. 

The booklets are quite educational for all ages so I often get the question, “Am I too old to participate?” Short answer: No! A lot of parks will allow anyone to participate, and encourage it! I highly recommend that you complete the Junior Ranger Program with your kids. Some of the most excited Junior Rangers Grace swore in was a group of college friends who were completing the program at every park they visited on a summer road trip. The oldest visitor sworn in as a Junior Ranger at Grand Canyon National Park was 103 years old!  The program is surprisingly educational for people of all ages!

Which Parks Participate?

There are 417 National Park Service Sites and over 200 of them offer a Junior Ranger Program. You can see a list of these places here. All of the most popular parks participate, and even some of the lesser known national parks. You can also check out the official www.nps.gov website for each park ahead of time to see if they have a Junior Ranger Program.  Some will even have pdf’s of the booklet that you can print out beforehand, like this one from Grand Teton National Park. This will allow you to see what the requirements are so that you can plan accordingly for your trip. 

Are There Different Types of Junior Ranger Programs?

In addition to the Junior Ranger Programs at each individual NPS site, there are other National Programs you and your child can participate in.

The current national programs are:

Parks are typically seasonal so there may be limited edition programs for special events. For example, the NPS Centennial Junior Ranger Program that happened during the 100th anniversary only occurred in 2016. There was also a special Solar Eclipse Program for the 2017 solar eclipse.  

National Parks Junior Ranger Program Activities

There are a couple of options for completing the Junior Ranger Program and earning a badge.

Print at home – mail In

You can download and print the booklet from home and when completed, mail it to the address provided on its webpage (see the links above). They will mail you back a badge or patch.

Print at home – work ahead

You can also download and print the booklet from home and then just bring the completed book with you to the park. Simply go to the visitor center at the park and the ranger can swear your child in and give them the badge or patch for that specific national program.  Just be sure to call ahead to ensure the specific park participates in the program.

Work in the park

You can complete the booklet and get sworn in at the park. Just make sure to call that park ahead of time and make sure they have the booklet and badge/patch you are interested in. Most parks have the booklets and swear people in at the visitor center.

Pro-tip: Call ahead!

Not every park has these booklets and badges/patches available for the national programs. It is helpful to call and make sure the park has the right booklet and badge/patch. Remember you can mail the booklet and have a badge/patch sent to you. This is helpful if get to the park and find out they are out of badges/patches for your particular national program. The mail in option is also a good back up plan if your kiddo is just not having it on the day of your visit.

Girl Scouts and Boy Scouts

The National Park Service has partnered with the Girls Scouts of the USA There are separate Junior Ranger Programs for Girl Scouts and Boy Scouts These programs are much more involved and require more planning beforehand but can be wonderful learning opportunities and additions to your child’s Girl or Boy Scout Program. Please click on the links above and read through the nps.gov webpage for each program’s details. You will find informational videos, additional links, and downloadable PDFs.  Girl Scout Adult Leader can find an entire page of information and resources on how to get involved.

What Will My Child Receive After Completing the Program?

When you complete the booklet you can take it to the visitor center for NPS site you are visiting and have a ranger look it over. Each park is different and each ranger is different on how they check out the booklet. Generally though, Rangers won’t be very strict or deny anyone a badge. As a ranger, I would check to make sure that the requirements were met, or at least there was effort to complete the booklet. I could tell when a child and their parents gave it their best shot and weren’t just trying to get away with a badge without putting in the work. 

A ranger will then swear in the participant by having them repeat a Junior Ranger Pledge. They will receive either a badge or a patch with the parks name and Junior Ranger on it. Some badges are plastic and some are wooden. I always thought Grand Teton had the coolest. Ours were wooden with a moose and if you smelled it, it smelled like campfire smoke. Each park is unique which is why collecting them all can be fun for your kiddos.  

This is the Mammoth Cave badge. This one is plastic with a pin on the back so be careful if you have super young kiddos.

Alternative Ways to Participate

Mail-in Programs

As I stated above, there are ways to complete the Junior Ranger Program by mailing in a completed booklet. Not every park offers this option but many do. This is great for when you aren’t able to get to a visitor center before having to leave the park. The mail-in option is also available for all Junior Ranger National Programs.

National Junior Ranger Day

Every year, the third or fourth week of April, the NPS hold National Park Week events. This week long celebration usually starts off with National Junior Ranger Day, followed by other events celebrating our public lands. National Junior Ranger Day usually means park fees are waived that day too. Not every NPS site celebrates National Junior Ranger Day but some have an entire days worth of activities planned. I helped plan and carry out National Junior Ranger Day at Grand Teton National Park for two years. The event was always fun and packed with locals and travelers alike. Find a park near you or where you will be traveling and see if they celebrate Junior Ranger Day.

Junior Ranger Program Tips

Before You Arrive

  • Check out the nps.gov webpage for whatever site you are visiting and/or give the park a phone call to ask about their program.
  • Find out if there are any seasonal closures affecting access to the Junior Ranger Program at a particular site.
  • Find out the age limits beforehand if you or someone older than ~13 years old wants to complete the booklet.
  • If completing a National Program, either call the park you are visiting beforehand to see if they have booklets and can swear you or your child in or print the booklet on your own and mail in to the provided address.


Many Junior Ranger Programs require you to attend a ranger-led program to complete the program. These are programs put on by rangers about a variety of park topics. Programs can be from short 20-minute programs to 2-hour hikes. Each park offers a wide variety. Program offerings are available on the park webpage, by calling the park, or grabbing a park newspaper when you arrive. Do your best to attend a program but if you really can’t get to one, talk to a ranger at the visitor center. Most will understand, as long as you tried, and can still swear you in.

When You Arrive

  • Grab a booklet and talk to a ranger at the visitor center.
  • Find out if you need to attend a ranger led program and grab a schedule from the visitor center.
  • Make sure you have time to get to a visitor center before it closed to get sworn in. If you do not have the time to make it to a visitor center before it closes, you can usually mail the booklet in after your trip and get a badge or patch. I talk more about that below.

NPS Ranger Pro Tips

Grace shared the following tips from having worked with hundreds of families completing the program. The Marley & Moose team is in full agreement and following these have been essential to how much we have enjoyed the program at a half dozen parks.  

Let the kids do the work

Don’t do the work for them. If your child needs help with the program, by all means, please help them, just don’t do the entire program for them. Grace and fellow rangers often received booklets that were clearly done by the parent hoping to fast track the process to get the badge. If your child can’t finish before the end of the trip, mail it in to receive your badges!

Talk to the rangers

Let them talk to the ranger! We haven’t yet met a ranger who wasn’t incredibly nice and kind. Wrong answers won’t get your child stripped of their chance at the badge. And most rangers love the chance to see young children getting excited about nature and public lands.

It’s not about the reward

Your child might get fixated on the “reward”, and we know some kids are going to get so focused on getting their badge that they rush through the activities. Try to keep them focused on the fun and the learning and actually enjoying the outdoors. At Arches NP during Covid, we got our badges upfront so rangers could minimize contact with guests, and we were having so much fun and the kids didn’t want to stop and work on their booklets back at camp on days one, two, or three, they wanted to explore more. We finished them back home and what a fun way to solidify everything they had learned.

Don’t stress

Don’t stress out about it! This program is not meant to be an added level of stress to your vacation. If things are going to plan when you are at the park just talk to a ranger at the visitor center. You want your park experience to be about the memories and the education and experience, not about a reward or checked box. Remember, most badges can be earned online, so you very likely will get a second chance back home if you wish.


  • Call or visit the park’s nps.gov website or check out this list to see if where you are going has an active junior ranger program.
  • Make time to attend a Ranger Led Program-most booklets require this and you can learn about the park from ranger!
  • Remember, the program is about connecting to a place, not about achieving the badge or patch.
  • Have fun and let the program help facilitate the experience, but not make or break it.
  • Do your research and always check out the nps.gov webpage and or give the park a call to help plan your trip.

It is never too late to start participating in the Junior Ranger Program. This goes for young kids and not so you kids alike. The Junior Ranger Program was created to help facilitate a positive outdoor experience–a tool for learning and exploration. There are many different ways to experience our public lands we happen to find this one particarly awesome.

Ranger Quotes

“The best part of my day is swearing in a new Junior Ranger.  The Junior Ranger Program is the reason I became a Ranger. As a kid it focused my attention so I could learn and not become overwhelmed. Today I make a point to introduce people at every skill level to the Junior Ranger Program. Many parks only require you be young at heart to become a Junior Ranger, so I continue to do books and collect badges. “

-Lucy Craft, Park Guide at Abraham Lincoln Birthplace National Historic Park, Longtime Junior Ranger

From Grace

Lucy was my mentor at Grand Teton National Park and continues to be that and a friend today.  She has shown me her Junior Ranger badges and patches from when she was a little girl. I’ve seen the faded photos of her visiting the national parks she would one day be a ranger at. I’m not saying every child who becomes a Junior Ranger will grow up to work for NPS. What I am saying is that it just might be the activity that makes that one trip that one summer, a lifelong memory. It just might be the activity that inspires a lifelong connection to the outdoors. It just might be the activity that inspires them to take their own kids to a national park one day.
