There are over 400 national parks covering over 84 million acres throughout the United States and its territories.  The majority of these parks do not charge entrance fees (though parking fees often apply). As for the roughly 110 national parks that do have entrance fees, there are a number of designated "fee free" days each year.

Here are the National Park Service Free Entrance Days in 2024:

• January 15 (Martin Luther King Jr. Day)

• June 19: (Juneteenth National Independence Day)
