From massive glaciers to sun-soaked beaches, national parks offer some of America’s wildest and most iconic landscapes. When the U.S. Congress established Yellowstone as the first national park in 1872, it was “for the benefit and enjoyment of the people.” Its founding marked the birth of the U.S. National Park System and eventually launched a worldwide movement to protect outdoor spaces and historical landmarks. Since 1904, some 15 billion visitors have explored the wild wonders of the U.S. parks. Inspired by the National Park Service, photographer Jonathan Irish inspired by the visited every U.S. national park over 52 weeks. “[National parks] are sacred and cherished places—our greatest personal and national treasures,” says Irish. “It’s a gift to spend a year adventuring and capturing incredible images and stories in some of the most beautiful places on Earth.” Since Irish’s journey, the National Parks Service has designated four additional parks: the Gateway Arch in St. Louis; Indiana Dunes on Lake Michigan; White Sands in New Mexico; and New River Gorge in West Virginia. There are now 63 spaces to explore across the country. Celebrate the grandeur of these priceless national treasures in images, from the crystalline waters of Dry Tortugas in Florida to the deep, dark recesses of Kentucky’s Mammoth Cave. 1. Zion National Park , Utah One of the most photographed views in Zion National Park is of Watchman Mountain from the Canyon Junction Bridge. Irish’s favorite spot is at the center of the bridge where the river leads the eye to the Watchman Spire in the background. 2. Yellowstone National Park, Wyoming, Montana, and Idaho America’s first national park, Yellowstone is home to wildlife from bears to bison and geological stunners such as hot springs and geysers. The Great Fountain Geyser, pictured here, erupts every 9 to 15 hours, shooting water up to 220 feet (67 meters) high. 3. Acadia National Park , Maine Avoid the crowds at Cadillac Mountain and see the first sunrise in the country at Bass Harbor Head Lighthouse, in the southwest portion of Acadia National Park. Bikers looking for the best trails in the park should consider these trails , once carriage roads. 4. Yosemite National Park , California Irish says the best time to see a rainbow in Yosemite is at night during a full moon. To photograph these so-called moonbows, he recommends a wide-angle lens, a tripod, and a lens cloth (to continually wipe off the waterfall spray). Visitors may want to consider staying at these 10 places when visiting the park. 5.

Cuyahoga Valley National Park , Ohio North of Hale Farm is Cuyahoga Valley’s Everett Covered Bridge, a reconstruction of an 1870s structure that was destroyed in a 1975 flood.

Katmai National Park , Alaska A brown bear (nicknamed “Uno” for her one ear) and her two cubs walk along a river in Katmai National Park and Preserve.
