In celebration of the signing of the Great American Outdoors Act, the Interior Secretary announced free entrance to national parks and public lands for August 5, 2020, and designated August 4th as the “Great American Outdoors Day.” In future years, every August 4 will be a free entrance day, joining the other scheduled entrance fee-free days which commemorate or celebrate significant dates. The Great American Outdoors Act will enable national parks and other federal lands to repair and upgrade vital infrastructure and facilities that will enrich the visitor experience, protect resources, and enable increased access for all visitors.
In the past, other fee-free days have included:
In January: Martin Luther King, Jr. Day
In April: First day of National Park Week (a weeklong event held at parks across the country)
In August: National Park Service Birthday
In September: National Public Lands Day
In November: Veterans Day
