Is Yellowstone Worth Visiting in September? Here’s What to Know

Yellowstone National Park is spectacular any time of year, but September might just be one of the best-kept secrets for travelers looking to avoid summer crowds and still enjoy great weather, active wildlife, and fewer traffic jams.

If you’re wondering, “Is Yellowstone worth visiting in September?” — the short answer is: Yes, absolutely. And here’s why.

What’s the Weather Like in Yellowstone in September?

September in Yellowstone brings the crisp, golden beginning of fall — a beautiful and refreshing time to explore the park.

Average Temperatures:

• Daytime highs: 55–65°F (13–18°C)

• Nighttime lows: 25–35°F (-4 to 2°C)

Higher elevations can get frost or even snow by mid to late September.

What to Expect:

• Mornings are cold, but afternoons are pleasant and sunny.

• Layered clothing is key: think warm jacket, fleece, and a rain shell just in case.

• Snow is possible in late September, especially at higher elevations like Dunraven Pass or Craig Pass.

  
  

Why September Is a Great Time to Visit Yellowstone

1. Smaller Crowds

Labor Day weekend can still be busy, but after that, the park gets noticeably quieter. You can explore popular spots like Old Faithful, Grand Prismatic Spring, or Lamar Valley without the summer congestion.

2. Incredible Wildlife Viewing

September marks the elk rutting season — a dramatic time when male elk bugle and battle for dominance. You can hear the eerie calls echo through valleys like Mammoth Hot Springs or Hayden Valley.

Other wildlife highlights:

• Bears are active, foraging before winter

• Wolves, bison, moose, and eagles are all visible in key areas

3. Gorgeous Fall Colors

While Yellowstone isn’t known for classic fall foliage, areas with aspens and cottonwoods start turning yellow in mid to late September, especially in Lamar Valley and along the Madison River.

4. Cooler Hiking Weather

The cooler temperatures make for perfect hiking conditions. Trails are less dusty, and you won’t be overheating. Just watch for icy spots in the mornings.

Getting Around in September: Shuttle and Tour Tips

As the season winds down, parking lots become less chaotic, but tour shuttles still offer convenience and guided insight — especially if you’re unfamiliar with the park or want to avoid driving.

Why Consider a Shuttle or Tour in September?

• Less stress: No navigating or parking worries

• Expert guides: Learn about geysers, wildlife, and geology

• Comfort: Relax and enjoy the scenery while someone else drives
