15 Best National Parks to Visit in September 

Looking for the best National Parks to visit in September? Explore stunning landscapes, vibrant fall colors, and pleasant weather in the most breathtaking national parks in the US!

As the warmth of summer slowly gives way to the crispness of fall, September is the month that US National Parks reveal the arrival of autumn as nature subtly shifts its palette to prepare for the colder months ahead. 

This transitional period offers an incredible opportunity to explore nearly any national park. The weather remains warm, and the higher-elevation trails are completely snow-free. 

In the northern half of the US, the parks retain their pleasant warmth, and the roads remain easily accessible. While regions like Utah and Arizona may still feel hot, September is a respite from the scorching heat of June and July, especially if you plan your visit toward the end of the month.

Plus, with the passing of Labor Day, the parks gradually shed their bustling crowds as families settle back into the rhythm of the school routine. Simultaneously, by the end of September, certain regions begin to display the first hints of fall colors, painting the foliage in a tapestry of reds, oranges, and golds.

With our exploration of 48 national parks to date, we have meticulously curated this guide showcasing the 15 best national parks to visit in September for an unforgettable trip! 

Tips for Visiting National Parks in September 

Plan Ahead: Check out the park’s regulations, permit requirements, and any reservations you might need. Some of the more popular National Parks might ask for advanced booking for campsites, accommodations, or activities.

Download Maps in Advance: National parks often have limited or no cellular network coverage. By downloading maps beforehand, you can access them offline, ensuring you have navigational guidance even without an internet connection. AllTrails maps are highly recommended, and it’s worth considering an AllTrails+ membership for $30 a year. 

Want to get 30% off an AllTrails+ membership? Click this link or use our code aplusk30 (you must redeem this code on the website, not the app)!

We use AllTrails+ on every single hike and it is the most helpful hiking tool out there! Some of the features we love are offline maps (so we can navigate even without cell service), wrong-turn alerts, and its 3D maps feature, so we can get a feel for trails before we hike.

America the Beautiful Pass: If you’re a National Park enthusiast and have a list of parks to conquer throughout the year, consider purchasing the America the Beautiful Pass. An annual pass for $80 lasts a year and grants you access to over 2,000 federal recreation sites, including our beloved National Parks. 

Mind the Pet Policies: We adore our furry companions, but it’s important to be aware of the pet policies in each park. To ensure the safety of wildlife and protect the park’s natural wonders, some trails and areas may be off-limits for pets. So, plan accordingly and make arrangements that keep your four-legged friends happy.

Embrace Leave No Trace: Pack out your trash, stick to designated trails, and minimize your impact on the environment. By doing so, we can preserve these beautiful landscapes for future generations.
