National ParkRx Day encourages everyone to start seeing visits to parks and public lands as very important parts of their health. Come out to enjoy FREE activities including Yoga presented by Yogabuzz, crossfit, blood pressure readings, walking tours of the Gateway Arch grounds, and so much more! The National Park Service will be leading Junior Ranger badge programming as well as the City Nature Challenge, an opportunity to observe and identify native species to the park using the iNaturalist app.
