At PureTravel we think there’s something magical about September travel. The summer rush is over, the air turns crisp in many places, and destinations that were packed just a month ago suddenly feel more welcoming. I’ve always found September to be the perfect balance—warm enough to enjoy the outdoors but without the stifling heat, and bustling cities still lively but not overwhelming. Whether you’re chasing fall colors, planning a beach escape, or looking for a cultural getaway, the USA has plenty to offer this time of year. Let’s dive into the best places to visit in the US in September!
1. Aspen, Colorado – A Golden Autumn Wonderland
As summer fades, Aspen’s famous aspen trees burst into brilliant shades of gold, making this mountain town one of the most breathtaking fall destinations. The cooler temperatures are perfect for hiking, biking, and scenic drives through Independence Pass or Maroon Bells. September also brings vibrant festivals like the Aspen Film Festival and the Snowmass Balloon Festival, adding an extra layer of charm to this alpine retreat. It’s no surprise that Aspen is considered one of the best places to visit in the US in September for outdoor lovers and fall foliage seekers alike
2. Yellowstone National Park (Wyoming/Montana/Idaho) – Wildlife and Natural Wonders Without the Crowds
September is one of the best times to visit Yellowstone. The crowds have thinned, but the park remains full of life—elk are in their rutting season, bears are busy preparing for winter, and geysers like Old Faithful continue their dramatic eruptions. The mild weather makes hiking more enjoyable, and you’ll start to see patches of fall foliage across the park’s vast landscape. If you’re looking for a national park adventure, Yellowstone easily ranks among the best places to visit in the US in September for nature enthusiasts.
3. New York City, New York – The City Comes Alive in Fall
New York City in September is electric. The sweltering summer heat gives way to perfect sightseeing weather, making it a great time to stroll through Central Park, visit iconic landmarks, or catch a Broadway show. September also kicks off the cultural season, with events like New York Fashion Week, the U.S. Open, and the lively Feast of San Gennaro in Little Italy. Whether you’re exploring the city’s rich history or indulging in its famous food scene, NYC is undeniably one of the best places to visit in the US in September for those craving an urban adventure.
4. San Francisco, California – The Best Weather of the Year
Unlike much of the U.S., San Francisco enjoys some of its warmest and sunniest days in September—locals call it “Second Summer.” This is the perfect time to explore Alcatraz, take in the views from Twin Peaks, or visit the vibrant Mission District. Plus, major events like the Folsom Street Fair and Hardly Strictly Bluegrass Festival add to the city’s dynamic atmosphere. With its blend of scenic beauty, culture, and perfect weather, it’s easy to see why San Francisco is one of the best places to visit in the US in September for travelers looking for an ideal mix of urban and outdoor experiences.
5. Great Smoky Mountains (Tennessee/North Carolina) – Early Fall Foliage and Misty Mountain Mornings
September marks the start of fall in the Great Smoky Mountains, with hints of red and gold beginning to appear among the green. The cooler air makes for comfortable hikes through Clingmans Dome or Cades Cove, and wildlife activity is at its peak. Nearby towns like Gatlinburg and Pigeon Forge offer charming music festivals and mountain culture, making it a well-rounded trip. If you’re looking for breathtaking landscapes and an early glimpse of fall, this national park is undoubtedly one of the best places to visit in the US in September for nature lovers.

7. Maui, Hawaii – Tropical Paradise Without the Crowds
If you’re craving a beach escape, Maui in September is perfect. The summer rush has ended, meaning fewer tourists and better hotel rates.

September also marks the Aloha Festivals, where you can immerse yourself in Hawaiian culture, music, and dance.
8. Boston, Massachusetts – Historic Charm Meets Autumn Vibes
Boston is at its best in September—mild temperatures, fewer tourists, and the first signs of fall appearing along the historic Freedom Trail.

The city also hosts the Boston Film Festival and Head of the Charles Regatta, adding even more cultural appeal.
9. Sedona, Arizona – Red Rock Adventures in Perfect Weather
Sedona’s scorching summer heat finally eases in September, making it the best time for outdoor adventures.

The Sedona Winefest in September offers a perfect blend of wine tasting and desert scenery, making for an unforgettable getaway.
10. Seattle, Washington – Sunny Skies and Artsy Vibes
September is one of the driest months in Seattle, making it an excellent time to visit before the rainy season kicks in.
