If you are planning to visit a National Park next year, you may be able to get in without paying a dime. The National Park Service (NPS) just announced five dates where visitors will not have to pay the entrance fee. This applies to all 111 national parks in the United States that charge a fee. The majority of parks don't charge a fee.

Typically, it costs between $15-35 per car to enter a park that charges an entrance fee. The five fee-free days in 2020 are as follows:

Martin Luther King Jr. Day – January 20

First day of National Park Week – April 18

National Park Service's Birthday – August 25

National Public Lands Day – September 26

Veterans Day – November 11

To see the full list of park sites, by state, you can do so at the NPS website. Keep in mind that even though there are five fee-free days where you can visit at no charge, those entering will still have to pay for extras such as special tours or to camp on-site.

Also, while there are over 400 National Park sites, many require no entrance fee at all. In fact, over 300 do not charge entry fees.

Senior citizens, active military, as well as disabled citizens can enjoy free or discounted admission any day of the year.

If you are a nature lover and love to visit parks all year, you may want to invest in an annual $80 America the Beautiful National Parks and Federal Recreational Lands Pass. This gives the pass holder unlimited entry to over 2,000 parks and recreation areas throughout the United States. The NPS just added its newest park, White Sands National Monument, this month.
