Monday, Jan. 20, is MLK Day, a national holiday set aside to honor Martin Luther King Jr. and to encourage Americans to participate in a day of service to celebrate MLK's legacy.

For many, this federal holiday means a day off from school and work. It also means that there is free admission to any one of the 401 national parks and historic sites around the country.  

MLK Day is just one in a series of free-fee days offered by the National Park Service each year. For the complete schedule of free admission days, check out this post. In the meantime, don't forget to take advantage of the opportunity this Monday to visit — or volunteer — at one of your favorite national parks. Take a hike, go for a drive or soak up some history in one of our country's national jewels.
