Best time to visit the United States

The best time to visit the USA? Honestly, any time – this country is huuuge. With such massive distances between regions, there's always somewhere that's having its 'best time of the year' moment, so the right time to go really depends on where you're headed and what you want to do. For national parks and hiking, spring and autumn are the sweet spots. Summer is Alaska's time to shine, and winter brings snowy mountain magic and comfortable conditions in the desert. It's a lot to process, we know – so here's a general seasonal guide to help you figure out when and where to go.

When to visit

Best time for national parks

For national parks, spring and autumn are the best seasons. Waterfalls roar in Yosemite in the spring, wildflowers pop up in Utah's Mighty 5 and the Grand Canyon's rim trails feel way more walkable without the summer sizzle. Autumn's crisp weather and warm colours make for ideal conditions in almost every park, especially the Tetons' golden aspen trees. If you're into mountains covered in snow, you might want to consider a winter visit, though higher elevation parks may have closures and limited access.

Best time for hiking

For most hiking destinations in the USA, the shoulder seasons of spring and autumn are going to bring the best conditions for outdoor activities when trails are colourful, covered in either wildflowers or foliage. Temps are comfortable and crowds aren't as hectic as during summer breaks. Summer is a great time to hike in Alaska (we'll chat about that in a minute), while winter can be brilliant for desert trails when the heat has backed off – we're looking at you, Joshua Tree.

Best time to visit Alaska

It's summer's time to shine, baby. From June to August, Alaska gets long, (mostly) sunny days and the great outdoors is at its finest and most accessible. Around the June solstice, you'll get up to 18 to 20 hours of daylight, giving you heaps of time for hiking in Denali, paddling around Kenai Fjords, plus glacier walkin' and wildlife spottin'. While it may be the busiest season, it's well worth it.

Spring (March-May)

Spring is when national parks shake off the winter chill, wildflowers bloom, and California and the Southwest states see sunny-but-not-too-hot days. It's a great time to travel before the summer crowds roll in, especially if you're keen to hit the trails, explore desert landscapes, chase waterfalls in Yosemite or explore other big-name parks with a little more breathing room and a whole lotta colour. Head to some of California's best parks, or hike by day and relax by night on a glamping adventure in Zion National Park.

Summer (June-August)

Long, sunny days make summer a fabulous time for glacier hiking in Alaska, river cruising in Montana or simply relaxing on the coast. The weather fluctuates a lot depending on where you are, like scorchin' heat in the desert but cool breezes up north. It can be a busy time in some parks, but you can squeeze in way more daytime adventures than other seasons. Plus, the warm nights make for ideal camping conditions, where a tiny, nocturnal chorus of frogs might serenade you to sleep under the stars. (Psst, it's the best time of year to see the Milky Way, too!)

Autumn (September-November)

Summer crowds thin out, temperatures settle down, and the landscapes transform with foliage, especially in the Tetons, Yellowstone and Yosemite. Just like spring, autumn is one of the best times to explore national parks with comfortable days on the trails and crisp evenings spent around the campfire. Or swap canyons for culture on a road trip from Nashville to New Orleans, where cooler days are made for wandering neighbourhood streets, catching live music and eating your way through the South.

Winter (December-February)

Winter can bring snowy adventures if that's your jam, but it's also the best time to hit the desert trails – especially in places like Arizona, Utah, Joshua Tree and the Grand Canyon, where cooler days make weaving through slot canyons and exploring mars-like landscapes feel even more otherworldly with less crowds. It's also a good season to pair the wild with the city life, like road tripping with new friends from desert parks to Las Vegas. Keep in mind that during winter, road closures are common and there can be limited access to higher elevation parks.
