Jaw-dropping pictures of all 63 of America’s stunning national parks

There are 63 national parks in America – but within them, a seemingly infinite variety of landscapes.

Here we showcase every single one with breathtaking photographs and in the captions tell you about their most fascinating features.

We invite you to scroll down and go on an armchair odyssey across 52.2million acres of nature at its most tantilising.

The virtual voyage will go south of the equator, above the Arctic circle, to towering volcanoes and epic glaciers, across prairies, above bizarre rock formations, through dramatic canyons, past some of the planet’s biggest trees, along some of its most photogenic coastlines and below ground, to caves of wonder.

Some of the parks are so remote you need a plane or helicopter to reach them. One is so otherworldly Nasa tests rovers on it. And one so big you could fit Switzerland inside it.

They’re wonderful for wildlife, heaven for hikers and irresistible for Instagrammers. And every one something to treasure.

Acadia National Park, in Maine, is the most easterly national park in the U.S and according to National Geographic, ‘is one of the first places in the United States to see the sunrise each day’. The park is home to Cadillac Mountain – the tallest mountain on America’s Atlantic coast at 1,529ft (466m). The National Parks Service (NPS) says: ‘Acadia National Park protects the natural beauty of the highest rocky headlands along the Atlantic coastline of the United States, an abundance of habitats and a rich cultural heritage’ 

Lonely Planet describes the spectacular Arches National Park in Utah as the place where 'giant sweeping arcs of sandstone frame snowy peaks and desert landscapes'. In fact, there are 2,000 documented arches spread across the area, the tallest being the Double Arch South, which has a vertical light opening of 112ft (34.1m). Pictured is the incredible view through North Window Arch, which is 51ft (15m) high and 93ft (28m) wide

The Badlands National Park in southwestern South Dakota is known for its beautiful undisturbed rolling prairie where coyote, elk, bison and white-tailed deer roam. But it's perhaps better known for its otherworldly multi-colored rock formations, which began forming 75million years ago as different types of rock were deposited on top of each other by seas, rivers and wind, 'like a layer cake' as the National Park Service puts it. The process ended around 28million years ago. These rocks, says the NPS, erode at a rate of one inch per 10,000 years and will have disappeared in 500,000 years

Located in Texas on the border between the U.S and Mexico, Big Bend National Park is named 'for the drastic change in course of the Rio Grande river from a southeastern to a northeastern flow', explains the National Park Service. It adds: 'As the Rio Grande flows through the Chihuahuan Desert, it carves not only majestic canyons, but also a political boundary. Big Bend's location on the United States/Mexico border has always provided a mystique to the park'

Around 7,700 years ago the colossal 12,000ft-tall Mount Mazama volcano in Oregon erupted, then collapsed and formed a caldera lake 4.9 miles (eight kilometres) wide and 5.9 miles (9.6km) long - Crater Lake. With a depth of 1,943ft, it's the deepest lake in America. Its formation was witnessed by Native Americans, who regarded the volcano as sacred. The lake - described by the NPS as 'one of earth's most pristine' - and its surrounding hills and forests now form Crater Lake National Park. Scientists discovered that around two million gallons of water seeps away from the lake every hour - but where it goes remains a mystery. The lake is regularly topped up by rain and snow - in fact Crater Lake receives around 43ft of snow annually, making it one of America's snowiest spots

Boat or seaplane are the two modes of transport needed to see the stunning Dry Tortugas National Park, which lies more than 70 miles off the coast of Florida's Key West in the Gulf of Mexico. The 100-square-mile park is mostly open water, coral reef and marine and birdlife. Just one per cent of the park is dry land and most of this comes in the form of seven small islands, including Garden Key. On this lies Fort Jefferson, pictured, a 19-hectare unfinished coastal fortress that was used as a prison during the Civil War. The park harbors some excellent spots for diving and snorkeling

Katmai was given national park status in 1980. Most visitors to the park reach it by floatplane and stay in Brooks Camp. Lonely Planet adds: ‘Here they [visitors] will stand spine-tinglingly close to formidable 1,000lb brown bears pawing giant salmon out of the river (some bears even catch the fish clean in their chops)’ 

Kenai Fjords National Park is located on Alaska's Kenai Peninsula and is 'a land where the ice age lingers', according to the NPS. Nearly 51 per cent of the park is covered by ice and it has almost 40 glaciers that flow from the Harding Icefield, which is described as the park's 'crowning feature'. The largest glacier is the 15-mile-long Bear Glacier, while the most popular with visitors is the four-mile-long Exit Glacier, pictured. The NPS says: 'It is a place where you can witness up close how glaciers re-shape a landscape and learn how plant life reclaims the barren rocky land exposed by a glacier's retreat'
