The USA’s national parks are more than just protected areas; they are vast landscapes of incredible beauty and diversity. From jagged mountain ranges and geothermal wonders to ancient forests and dramatic coastlines, these parks offer some of the most memorable travel experiences in the world. Deciding which ones to visit can be a challenge, so we’ve highlighted some of the very best to help inspire your next adventure.

Yellowstone National Park
As the world’s first national park, Yellowstone sets a high standard. It’s famous for its unique geothermal features, including the ever-reliable Old Faithful geyser which erupts with impressive regularity. Beyond the geysers and bubbling hot springs, the park is a sanctuary for wildlife. It’s common to see vast herds of bison roaming the valleys, and you might even spot bears or wolves. The best time to visit is from late spring to early autumn when roads and facilities are fully open.

Yosemite National Park
Located in California’s Sierra Nevada mountains, Yosemite is a masterpiece of granite cliffs, powerful waterfalls, and ancient giant sequoia trees. The park’s icons, El Capitan and Half Dome, are legendary among climbers and photographers alike. In the spring, the park’s waterfalls are at their most spectacular as the snow melts. Visiting between May and October ensures full access to all areas, including the high-altitude Tioga Pass.

Glacier National Park
For breathtaking mountain scenery, it’s hard to beat Glacier National Park in Montana. Known for its turquoise lakes, carved valleys, and, of course, its glaciers, the park is a hiker’s paradise. The Going-to-the-Sun Road is one of the most scenic drives in North America, offering unbelievable views at every turn. The ideal time to visit is during the short summer window of July to September, when the famous road is fully clear of snow.

Great Smoky Mountains National Park
Straddling the border of Tennessee and North Carolina, the Great Smoky Mountains are named for the persistent morning fog that settles over the rolling hills. This park is celebrated for its incredible biodiversity, with dense forests and countless waterfalls. It’s a wonderful destination year-round, but spring brings a spectacular display of wildflowers, while autumn transforms the landscape with brilliant foliage.

Grand Teton National Park
Just south of Yellowstone in Wyoming, Grand Teton makes an immediate impression with its sharp, jagged peaks rising straight from the valley floor. The park is a haven for outdoor enthusiasts, offering pristine lakes for kayaking, miles of hiking trails, and fantastic opportunities for wildlife watching. The scenery is particularly stunning from summer into early autumn, when the weather is ideal for exploring.

Other, perhaps lesser known, national parks are also well worth a visit too. Acadia National Park in Maine combines dramatic coastal cliffs with the thrill of being one of the first to see sunrise from Cadillac Mountain. Death Valley National Park, straddling California and Nevada, stands out for its striking desert scenery and extreme conditions, best experienced during the cooler parts of the year. Down in Florida, Everglades National Park is a haven for wildlife enthusiasts, with subtropical wetlands providing a home for alligators, manatees, and a dazzling variety of birds.

Is your favourite one not on my list? I have planned so many different itineraries it’s hard to know where to start and what to include. But if you’re thinking of a road trip across USA to explore some of these destinations then please get in touch, I’d love to help make it memorable (for the right reasons).
