The National Park Service invites the public to experience all national parks on four days in 2018. The 2018 entrance fee-free days are:
- January 15: Martin Luther King, Jr. Day
- April 21: First Day of National Park Week
- September 22: National Public Lands Day
- November 11: Veterans Day
Fee-free days for national parks mark opportunities for the public to participate in service projects, enjoy ranger-led programs, or just spend time with family and friends exploring these diverse and special places.
Last year, 331 million people visited national parks, spending $18.4 billion, which supported 318,000 jobs across the country and had a $35 billion impact on the U.S. economy.
