North America might only be the world’s third-largest continent, but it’s arguably the most diverse. This is a land of rocky canyons, hulking glaciers, soaring mountains, dense forests, pristine lakes, and vast, sun-scorched deserts. But North America isn’t just home to staggeringly beautiful scenery; it also boasts some of the most impressive national parks in the world.
North America’s national parks are far more than protected areas of wilderness; they’re corners of the continent that inspire awe. Whether it’s towering redwoods, smoking volcanoes, or alligator-filled wetlands, these national parks never fail to inspire – and if you’re looking for an outdoor adventure, they’re the best place to head.

1. Yellowstone National Park, Wyoming, USA
Yellowstone isn’t just the oldest national park in North America; it’s the oldest in the world. Since it was first designated in 1872, its dramatic, unearthly beauty has awed visitors from all across the globe, and today it remains one of the most visited national parks in the US. Shaped over millions of years by geological activity, Yellowstone is essentially a vast volcanic playground.
Here you can find the world’s most impressive concentration of hydrothermal features, from geysers and mud pots to hot springs. There are over 900 miles of hiking trails that wind past gleaming lakes and alpine tundras, and through rugged canyons and glacier-carved valleys. Then there’s the wildlife: keep an eye out for bears, deer, moose, wolves, elk, bison, and bighorn sheep, to name a few.

2. Yosemite National Park, California, USA
It might not be the oldest, nor the biggest, but California’s Yosemite National Park is certainly a contender for the most spectacular and iconic. It’s packed with more natural wonders than you can imagine, from the highest waterfall in North America (Yosemite Falls) to the world’s tallest granite monolith (El Capitan, which rises a dizzying 3,000 ft).
Thanks to the many skyscraping monoliths dotted across the landscape, Yosemite is beloved by climbers – but there’s just as much here to please even the most discerning hiker. This park’s glacier-carved beauty is breathtaking, and the memories of hiking through soaring sequoia forests, rugged canyons, and snow-capped mountains will stay with you forever.

3. Denali National Park, Alaska, USA
If you’re searching for raw, untamed wilderness – a chance to feel like you’re the only person in the world – then few places can match Denali National Park. Alaska is known as the USA’s last frontier, and it’s one of the wildest and most remote places in North America. Due to Alaska’s sheer size ( more than twice the size of Texas!), exploring can be tricky, which is why Denali is a must-visit.
A single road cuts through this six-million-acre wilderness, giving you access to the astounding scenery. Here, you can admire North America’s tallest mountain, do some incredibly challenging trekking, experience a unique sense of peace and tranquillity, and spot wildlife including bears, moose, caribou, sheep, wolves, and eagles.
4. Banff National Park, Alberta, Canada
As Canada’s top tourist attraction and the gateway to the Canadian Rockies, the beauty of Alberta’s Banff National Park is certainly no secret. Regularly topping lists of the most beautiful places on Earth, Banff draws millions of visitors from around the world – and while you may encounter crowds at some of its most famous sites, there are also plenty of places to find solitude.
Lake Louise and the town of Banff are always busy, but still worth visiting – particularly if you fancy canoeing. But there are 1500 km of trails to explore here, and no matter which path you pick, you’re guaranteed sublime scenery. From thundering waterfalls and churning rivers to majestic mountains and alpine meadows – and even hot springs – Banff is as dazzling as it is diverse.

5. Grand Canyon National Park, Arizona
Home to one of the Seven Natural Wonders of the World, it’s no surprise that Grand Canyon National Park is one of the most famous – and popular – parks in the USA. No matter how many videos or photos of the Grand Canyon you might have seen, nothing can prepare you for seeing it in person. The sheer size and beauty of this canyon may leave you speechless.
If you’re interested in geology, you’ll be fascinated by how the canyon walls tell a story that’s two billion years old. The colour of the canyon changes from yellow to orange as the sun moves across the sky, and staring down into the shadowy abyss from the canyon’s edge is a truly magical experience. If you like adventure, you can go hiking or whitewater rafting along the Colorado River.
6. Crater Lake National Park, Oregon, USA
Home to craggy cliffs, sandy beaches, and dense coniferous forests, the state of Oregon is beautiful…but nowhere is more impressive than Crater Lake National Park. The lake itself lies inside the collapsed summit of a now-dormant volcano, and the water is an astonishing sapphire blue. It’s the deepest and clearest lake in the country, and the waters are some of the purest in the world.
The lake is perfect for swimming and, in the summer, you can take a boat over to Wizard Island, a volcanic cinder cone that rises 800 ft above the water’s surface. While the lake is the heart of the park, there are 90 miles of hiking trails that weave their way through ancient forests, wildflower meadows, and over wooded peaks, so hikers and photographers will be spoilt for choice.

7. Hawaiʻi Volcanoes National Park, Hawaii, USA
If you’re interested in the power of nature, few places in the world compete with Hawaiʻi Volcanoes National Park. Home to two active volcanoes, the landscape rises 13,677 ft from the palm-fringed coastline to the smoking summit of Mauna Loa. Hawaiʻi Volcanoes is one of the most volcanically active spots in the world, a place where you can see land being born before your eyes.
The park was established to protect this unique geological, biological, and cultural landscape, and during your visit, you can learn about the significance of the volcanoes to local Hawaiian culture. Excellent hiking trails wind through the park, and the scenery will take your breath away as you trek through lush rainforests teeming with birds, eerie lava tubes, and alpine tundra.

8. Jasper National Park, Alberta, Canada
Stretching 4,200 square miles, Jasper National Park is the largest in the Canadian Rockies – but it isn’t just its size that makes it worthy of a place on this list. Jasper National Park is a magnificent part of the world, a region that’s wild in every sense of the word…and it’s also full of fascinating wildlife, from grizzly bears and wolves to moose, elk, and eagles.
The landscape is just as inspiring, comprising towering rock spires, sweeping valleys, foaming rivers, rugged mountains, emerald-green lakes, and cascading waterfalls. There are over 100 ancient glaciers here, and you can admire them simply by driving along the phenomenally scenic Icefield Parkway. But it’s the hiking Jasper is most famous for – and, luckily, there are more than 600 miles of trails.

9. Great Smoky Mountains National Park, Tennessee, USA
While Yellowstone, Yosemite, and Grand Canyon may be some of the US’s best-known national parks, they’re not the most visited. That honour falls to the Great Smoky Mountains National Park, which straddles the border of Tennessee and North Carolina. Stretching a whopping 522,427 acres, the park is stupendously picturesque and is home to one of Earth’s oldest mountain ranges.
There are over 850 miles of hiking trails that cut through the park, taking you through shady forests, over mist-shrouded peaks, and past plunging waterfalls. Mornings are especially brilliant here, as the fog causes the ridgelines to haze against the sky, which gives the mountains their iconic smoky look. The flora and fauna are just as impressive as the views, so don’t forget your camera!

10. Arches National Park, Utah, USA
Utah is home to five national parks, but Arches National Park is arguably the most impressive. The landscape here is otherworldly, and there’s nowhere on the planet with such a large array of natural arches, whittled down over millions of years by water and wind. There are over 2,000 arches here, and the grand, craggy landscape has a timeless and indestructible quality.
If some scenery looks familiar, it’s because the park appears in countless films, from Thelma & Louise to Indiana Jones, and the soaring spires and jagged pinnacles look incredibly cinematic against the huge blue sky. Arches is especially popular with thrillseekers, who enjoy climbing the peaks, jumping off, and even mountain biking over them. But for something more laid-back, hiking here is just as fun.
