Free National Parks Days 2025

Sometimes you’ve just got to get away from it all and clear your head with the peace and serenity of a national park.

On certain “fee-free” days throughout the year, enjoy free entry to all national parks and monuments including Muir Woods and Yosemite National Park, and free admission aboard all of the historic vessels at the Hyde Street Pier of SF’s Maritime National Historical Park.

Please always check with each National Park before heading out to confirm that the park and its facilities are open and admission is free.

Free Entrance Days in the National Parks | 2025

The National Park Service now offers six free days a year. All National Park Service sites that charge an entrance fee will offer free admission to everyone.

National parks are America’s best idea, and there are more than 400 parks available to everyone, every day. The fee-free days provide a great opportunity to visit a new place or an old favorite, especially one of the national parks that normally charge an entrance fee. The others are free all the time.

The entrance fee waiver for fee-free days does not cover amenity or user fees for activities such as camping, boat launches, transportation, or special tours.

In addition, there are also free or discounted passes available for senior citizens, current members of the military, families of fourth-grade students, and disabled citizens. Learn more about the variety of passes offered by the America the Beautiful National Parks and Federal Recreational Lands Pass series.
