This annual event, traditionally held on the second Saturday in June, encourages people to lead healthy, active lifestyles and connect with nature. To celebrate, the U.S. Forest Service often waives standard day-use fees at national forests and grasslands to increase public access. 

The day is coordinated by the Outdoor Recreation Roundtable and the U.S. Forest Service. Activities can include fishing, kayaking, hiking, archery, and bird watching.
