Whether you crave the desert’s dry heat, dream of alpine summits, revel in tropical sunshine, or live for the rocky beaches of the North Atlantic, America’s national park system has what you’re looking for. While some national parks and monuments are free, over 100 national parks, monuments, seashores, and battlefields are fee-charging.
Visit battlefields, monuments, and military parks to explore history. Enjoy the waves and water at national seashores and lakeshores. Take a driving tour on one of America’s four national byways or go rafting on one of 10 wild and scenic rivers. Wherever you choose to go, there’s a KOA campground close by. Over 500 KOA campgrounds across the country have roomy campsites and comfortable cabins, loads of family activities to wind down after a day in the national parks, and friendly staff who are ready to help you get the most out of your park visit.
Visiting the national parks is one of the most economical vacation options there is, but it’s never more affordable than on six free entry days, when all the national park sites that normally charge an entry fee of as much as $35 offer free admission. Pick a new park to explore, or return to an old favorite, to celebrate these special park holidays in 2025.
When are All National Parks Free? Visit National Parks for Free on These Six Days
Martin Luther King, Jr. Day – January 20
First Day of National Park Week – April 19
Juneteenth National Independence Day – June 19
Anniversary or the Great American Outdoors Act – August 4
National Public Lands Day – September 27
Veterans Day – November 11
Martin Luther King, Jr. Day – January 20
Monday, January 15 is the first admission-free day of the year, and hundreds of volunteers will be participating in park service projects to honor the occasion. Check a park near you for volunteer opportunities, or celebrate with a visit to the Martin Luther King, Jr. Memorial in Washington, DC, a journey along the 46-mile Selma to Montgomery National Historic Trail in Alabama, or a visit to Georgia’s Martin Luther King, Jr. National Historical Park.
First Day of National Park Week – April 19
Kick-off National Park Week by participating in a ranger-led hike, interpretive program, or Park Week festival on fee-free Monday, April 20. Pick one of the National Park’s least visited sites, like Craters of the Moon National Monument in Idaho, Ebey’s Landing National Historical Reserve in Washington, or Bighorn Canyon National Recreation Area in Montana and Wyoming, all as spectacular as any national park but a lot less crowded.
Juneteenth National Independence Day – June 19
One of the oldest known commemorations of the abolition of slavery in the United States, Juneteenth National Independence day is the newest federally recognized holiday and a new addition to the fee-free days at national parks. Juneteenth celebrates the final emancipation of enslaved African Americans, which took place in Texas in 1865, three years after the Emancipation Proclamation. Consider a visit to Harriet Tubman Underground Railroad National Monument or Mammoth Cave National Park – where enslaved Black people and later generations of Black guides helped develop modern cave exploration.
Anniversary of the Great American Outdoors Act – August 4
Passed in 2020, the Great American Outdoors Act (GAOA) provides funding to improve infrastructure and expand opportunities for recreation in national parks and other public lands. Providing billions of dollars to make significant enhancements to America’s national wonders, the GAOA is critical to ensuring preservation and education for current and future park visitors. Go rafting in Glacier National Park, cycle the paved Shark Valley loop in the Everglades, try fishing in Denali or Voyageurs, or stay up late to enjoy the starry skies in Death Valley.
National Public Lands Day – September 27
Established in 1994, National Public Lands Day is held the fourth Saturday in September and is traditionally the nation’s largest single-day volunteer effort celebrating the connection between people and green space in their community. Hike a portion of the Appalachian Trail or Wisconsin’s Ice Age Trail. Paddle California’s Trinity and Klamath Rivers or Missouri’s Ozark National Scenic Riverways. It’s also the perfect opportunity to look for volunteer opportunities in your nearby parks and nature areas. As an added benefit, when you volunteer in the parks on September 28, you’ll receive a one-day pass to use on another park visit in the future.
Veterans Day – November 11
The final fee-free day of the year falls on Veterans Day to commemorate and honor the service of American veterans. Choose a battlefield, military park, or historic site to visit on November 11 and learn about the men and women who gave their lives in defense of our country. Take a trip to Mount Rushmore in South Dakota to learn about the iconic sculpture of four legendary presidents, or the USS Arizona Memorial at Pearl Harbor to see where World War II began for the U.S in 1941.
