The bill aims to provide free admission or use of federal recreational lands and waters on certain days each year to encourage volunteerism and celebrate national pride. These fee-free days will align with important dates and holidays, such as Martin Luther King, Jr.'s birthday, National Park Week, Juneteenth, Great American Outdoors Day, National Public Lands Day, and Veterans Day. The bill also amends the Federal Lands Recreation Enhancement Act to require the Secretary to provide these fee-free days each year and gives the Secretary additional authority to provide for more fee-free days as deemed necessary.
