Yellowstone, Yosemite, Grand Canyon: the US National Parks Association manages a total of 423 protected areas, including national parks, memorials, coastal areas, and recreational areas.

Of these, 115 cost entry, and visitors must pay between $5 and $35 to explore famous sights such as the Grand Canyon ($20-35) or Yellowstone Park ($25).

But according to an announcement from the US National Park Service (NPS), visitors will enjoy free admission to parks on these five days in 2022:
