The Iron Ranger Challenge is back for its 6th consecutive year! Over the last 5 years, we’ve had over 1,000 folks hike, bike, swim, or paddle 100 miles on Arkansas public lands. We’re so proud of all that you’ve explored and hope that you’ll join us again for another adventurous year.

The 2021 Iron Ranger Challenge will continue to hold true to its roots, complete 100 miles of physical activity on any public lands within the state of Arkansas and you are eligible to become an Iron Ranger. This means any activity you do in an Arkansas National Park, Arkansas State Park, Arkansas Game & Fish Commission lands, US Forest Service site, National Wildlife Refuge site, Army Corps of Engineers site, or city park can be counted. Activities should be self-propelled so things like walking, running, hiking, biking, swimming, and paddling all count towards the 100 mile goal!

The 2021 Iron Ranger Patch

This year’s Iron Ranger patch will be a bit different than the previous years designs. 2021 marks the 100th anniversary of Hot Springs National Park as a national park and so, to commemorate this historic event, we’ve designed a patch to celebrate that milestone.

Hot Springs National Park will be hosting special events all year long, so be sure to visit the centennial webpage to learn about ways you can get involved in this once in a lifetime celebration. Be sure to also check our calendar of events and the Iron Ranger Facebook page throughout the year for other fun and unique opportunities in which you can earn miles.

You are free to keep track of your miles however you best see fit. If you would like a pre-made form that you can print and track your miles, check this one out. Once you complete your 100 miles, please email your completed form(s) to hosp_anniversary@nps.gov or send them in the mail to:

Buffalo National River
