Our national parks offer something for everyone – kids, adventurers, history buffs and fitness enthusiasts alike! In celebration of National Park Week, April 21-29, Gateway Arch National Park, one of six national parks in Missouri, invites you to a variety of special events happening at the park.

On Saturday, April 21, kids ages 5-15 are invited to participate in Junior Ranger Day beginning at 9 a.m. at the Gateway Arch and Old Courthouse. (And April 21 is also a fee-free day, so enjoy $3 off adult Tram Ride to the Top tickets and free Arch Entry-Only tickets.)

Kids can be the first to earn a Junior Ranger badge featuring the new Gateway Arch National Park name by completing a Junior Ranger activity booklet. Just visit the information desk at the Arch or Old Courthouse to pick up the booklet and to take part in these special ranger-led Junior Ranger programs:

• 9 a.m.-3 p.m.: Kids can take part in a variety of activities at the Old Courthouse, including dressing up like a park ranger and getting their photo taken, completing an NPS map activity and completing a Junior Ranger activity booklet to earn a Gateway Arch National Park Junior Ranger badge. (Also offered Sunday, April 22.)
• 9 a.m. to noon: Meet 16-year-old Aida Frey, “the most decorated Junior Ranger in the country” in the Gateway Arch lobby. Since July 2010, Aida has visited 304 national parks in seven years, earning her Junior Ranger badge at each. Aida will also be available to sign copies of her book “America, Can I Have Your Autograph?: The Story of Junior Ranger Aida Frey,” which is available for purchase at The Arch Store.
• 10 a.m.-2 p.m.: Former Gateway Arch National Park Ranger Nancy Hoppe, author of an article in the book “The Wonder of It All: 100 Stories from the National Park Service,” will be signing copies of the work in the Old Courthouse Rotunda. (Also offered Sunday, April 22 from 1-3 p.m.)
• 11 a.m.: A special Junior Ranger swearing-in ceremony with Aida and the day’s new Junior Rangers will take place in the Gateway Arch lobby. Those who’ve completed their activity booklet will be awarded the new Junior Ranger badge featuring the park’s new name, Gateway Arch National Park.

Then on Sunday, April 29, visitors of all ages are invited to Luther Ely Smith Square at Gateway Arch National Park for ParkRx Day, a nationwide initiative that encourages everyone to start seeing visits to parks and public lands as very important to human health. All events are free.

Special ParkRx Day events include:
