Visiting a national park can be a breathtaking experience. From snowy trails to wildflower meadows, the best national parks in the U.S. offer something magical year-round.
Whether you’re chasing fall colors or escaping the summer heat, this guide helps you time your visit for the best weather, lightest crowds, and most unforgettable views.
Winter: Desert Calm and Snowy Silence
Looking for peaceful landscapes and fewer crowds? Winter is the ideal time to explore desert parks or snow-covered scenery without the usual tourism surge. Before you visit, please check the National Park Service website for seasonal closures and current alerts.
Best national parks in winter:
- Death Valley (CA/NV): Enjoy the salt flats and golden dunes under crisp blue skies, with daytime temps in the 60s.
- Everglades (FL): Dry season draws out wildlife like gators, manatees, and tropical birds.
- Yosemite (CA): Visit in February to see the famous Firefall, plus snowy cliffs and frozen waterfalls.
Crowd Level: Low
Climate Tip: Winter brings mild desert weather and stunning snowy vistas in higher elevations.
Spring: Bloom Season and Perfect Trails
Spring brings blooming flowers, waterfall runoffs, and cooler temperatures, which are ideal for active travelers. Many national parks are at their most photogenic between March and May. You’ll want to book early because of the spring break crowds at popular parks.
Top spring national parks:
- Grand Canyon (AZ): Comfortable weather and clear views make spring a prime time for rim hiking.
- Zion (UT): Waterfalls peak and flowers burst across canyon walls.
- Big Bend (TX): A hidden gem with blooming cacti and fewer crowds.

Climate Tip: Spring is the best season for desert hikes and low-altitude trails before summer heat sets in.
Summer: Epic Views and Alpine Adventures
Summer unlocks access to high-altitude parks, alpine lakes, and longer daylight hours. It’s the most popular time to visit, but also the busiest. Skip desert parks like Joshua Tree and Death Valley. Temperatures during summer can exceed 115°F.

Fall: Colorful Trails and Crisp Air
Fall is a favorite for seasoned park-goers who want cooler temps, golden foliage, and lighter crowds. It’s the perfect time for road trips and photography. Bring a light jacket. Temperatures drop quickly in the evening, especially in the mountains.

- Great Smoky Mountains (TN/NC): Home to some of the most stunning fall foliage in the U.S.
