More Than 100 National Parks Are Waiving Fees on Martin Luther King Jr. Day

The National Park Service is hosting five "free days" in 2020—the first of which lands on January 20. In honor of Martin Luther King, Jr. Day, the NPS is waiving its regular entrance fees at 110 national park properties around the country, USA Today reports.

Of the 400-plus parks managed by the agency, 110 charge admission fees ranging from $5 to $35. These include some of the most popular sites in the system, like Yosemite, Yellowstone, and Grand Canyon national parks.

Every one of those parks will be free to visit on Monday. Martin Luther King, Jr. Day is a day of service, and parks across the U.S. will be hosting service projects for volunteers looking to give back to their communities. If you'd like to participate, you can find volunteer opportunities at your local NPS property here.

If you're just looking for a place to reflect, you can't go wrong with any of the sites in the national park system. Before planning a visit to one the parks below participating in the free day, read up on these facts about Dr. Martin Luther King, Jr.
