Did you know there are 20 national parks, monuments and historic sites in Arizona? Everyone knows about Grand Canyon, but there are many more natural wonders to explore on federal land in Arizona.

If that’s not enough incentive to get out and explore our public lands, get this: a few days each year, the National Parks Service allows free entrance to all park properties.

Take Petrified Forest National Park for example. Just a few miles from the town of Holbrook, you can explore hundreds of acres of land where the fossilized remains of massive prehistoric trees adorn the landscape. Bonus: a sizable swath of the beautiful Painted Desert passes through the north end of the park. You can also experience ancient ruins and petroglyphs.

Then there’s Saquaro National Park near Tucson. Explore trails that weave through stands of Arizona’s iconic cactus that are so tall and dense you’ll feel like you’re walking in a forest.

How much is admission to National Parks on normal days?

Daily admission fees vary from park to park. To enter Grand Canyon National Park, a 7-day pass costs $35 per vehicle. A permit to Petrified Forest or Saguaro National Park is only $25. Many of the national monuments and historical sites are free to access year-round.

Best value: annual pass

If you plan on visiting multiple park properties throughout the year, the America the Beautiful annual pass is the best value at $85 per year. Free and reduced rate passes are available for military members, seniors, some parks volunteers and, get this, fourth graders.

How the National Parks came about

America’s National Parks are the result of efforts by the U.S. Government to designate certain federally-owned land parcels as “public parks or pleasuring-ground for the benefit and enjoyment of the people.” Yellowstone National Park was the nation’s first, after receiving Congressional approval in 1872. Next came Sequoia (1890), Mt. Rainier (1899), Crater Lake (1902) and Yosemite (1890).

Grand Canyon National Park received its designation in 1919. President Herbert Hoover signed Saguaro National Park into existence in 1933. Petrified Forest didn’t have national park status until 1962, but earned protection as a national monument by President Theodore Roosevelt in 1906.
