One of the terrific things about the National Park Service - aside from its incredible duty to serve as the caretaker of America's greatest outdoor spaces - is the annual designation of five days during the course of the year that are free to the public.
Those five days have been announced for 2020.
n Jan. 20: Martin Luther King Jr. Day
n April 18: First day of National Park Week (a weeklong celebration of all parks)
n Aug. 25: National Park Service Birthday
n Sept. 26: National Public Lands Day
n Nov. 11: Veterans Day
On those five days, you can visit any national park across the country without paying an entrance fee.
Full disclosure - three-quarters of America's national parks are already free, according to Travel+Leisure. Of the 419 National Parks, 308 do not require an entrance fee.
That said, the remaining 111 are among the most popular and most visited - think Yosemite National Park - and charge anywhere from $5 per car to $35 per vehicle as an entrance fee.
Travel+Leisure also noted that the 111 parks that do charge fees use that money to benefit the parks themselves - 80% of the money stays with the park where you paid the fee, and 20% goes to the other 308 parks that do not charge an entrance fee.
The magazine also made a great point that if you plan to visit several national parks in 2020, consider getting the America the Beautiful pass for $80. The pass allows you to visit hundreds of national parks and federal recreational lands for a year without paying entrance fees.
