Great Smoky Mountains National Park

Great Smoky Mountains National Park is one of the best national parks in the United States for fall foliage. In October the mountains are covered with brilliant shades of red, orange, and yellow.

Because the park has such a wide range of elevations, fall colors last for several weeks.

October is also a great time for scenic drives and hiking since the weather is cool and comfortable.

Best time to visit: mid to late October

Highlights include:

Acadia is one of the most beautiful national parks to visit in the fall. Located on the coast of Maine, this is one of the most perfectly set National parks and you will find colorful forests with dramatic ocean views.

October is peak foliage season in this region, which makes the scenery especially stunning.

Visitors love hiking the granite mountains, driving the scenic Park Loop Road, and watching the sunrise from Cadillac Mountain.

Joshua Tree National Park

October is a great time to visit Joshua Tree National Park because the intense summer heat finally begins to ease. Daytime temperatures are much more comfortable for hiking and exploring, while evenings in the desert can be surprisingly cool.

Joshua Tree is also completely different from the foliage-filled parks you might normally think about visiting in October. Instead of fall colors, you’ll find huge rock formations, wide-open desert landscapes, and the strange Joshua trees that make the park feel almost otherworldly.

You can see a lot of Joshua Tree in just a couple of days. Drive through the park, stop for a few shorter hikes, explore the rock formations, and stay after sunset if you can. With very little light pollution, the night sky is one of the best parts of visiting.

Best for: desert scenery, hiking, stargazing
How long to stay: 1–2 days
Best time to visit: mid to late October

Highlights include:

Saguaro National Park

If you’re not ready for cold fall weather, Saguaro National Park is a great national park to visit in October. Located just outside Tucson, Arizona, the park is filled with enormous saguaro cacti and beautiful desert landscapes that look completely different from most of the other parks on this list.

October brings more comfortable temperatures after the intense heat of summer, making it much easier to hike, take a scenic drive, or simply stop at the overlooks. I especially like Saguaro for a shorter national park trip because you don’t need several days to get a good feel for the park.

Try to stay through sunset if you can. Watching the sky change color behind the silhouettes of the giant saguaros is one of the best ways to end a day in the park.

Best for: warm weather, desert scenery, scenic drives
How long to stay: 1–2 days
Best time to visit: mid to late October

Highlights include:

• Cactus Forest Drive
• Desert Discovery Nature Trail

Best National Parks in Early October vs. Late October

October can be a tricky month for national parks because conditions change quickly. A park that’s perfect during the first week of October can be cold or snowy by the end of the month, while some parks don’t reach their best fall colors until later.

Best National Parks to Visit in Early October

If you’re traveling during the first half of October, I would choose Rocky Mountain, Yellowstone, or Acadia National Park.

Rocky Mountain National Park is beautiful in early October when you may still catch golden aspens and fall wildlife activity.

Yellowstone National Park is also better earlier in the month. Temperatures drop quickly as October progresses, and services and roads become more limited as the park moves toward winter.

Acadia National Park is a great early-to-mid-October choice if fall foliage is your priority. The combination of colorful trees, rocky coastline, and ocean views is spectacular.

Best National Parks to Visit in Late October

For the second half of October, head toward Great Smoky Mountains, Shenandoah, Zion, Joshua Tree, Saguaro, or the Grand Canyon.

Great Smoky Mountains and Shenandoah are two of my favorite choices for a classic fall trip. Lower elevations can hold onto their color later in the month, so there’s usually more flexibility than in northern or high-elevation parks.

Late October is also when I’d start looking seriously at the Southwest. Zion, Joshua Tree, Saguaro, and the Grand Canyon offer cooler temperatures than summer, making hiking and sightseeing much more comfortable.

What About Bryce Canyon?

Bryce Canyon can be beautiful in October, but be prepared for cold temperatures and the possibility of snow, especially later in the month. That isn’t necessarily a reason not to go—the orange hoodoos can look spectacular with snow—but pack for conditions that may feel much more like winter than fall.

Frequently Asked Questions About Visiting National Parks in October

What is the best national park to visit in October?

Great Smoky Mountains National Park is my top choice for October, especially if you want fall foliage. The changing colors, scenic drives, and cooler hiking weather make October one of the best times to visit. If you’re more interested in desert scenery and hiking, Zion and Joshua Tree are also great October choices.

Which national parks have the best fall colors in October?

Great Smoky Mountains, Shenandoah, Acadia, and Rocky Mountain are some of the best national parks for fall colors. Timing varies by elevation and weather each year, so early October tends to be better for northern and high-elevation parks, while foliage can last later in the month in the Smokies and Shenandoah.

Are national parks crowded in October?

Many national parks are less crowded in October than during the peak summer months, but popular fall foliage destinations can still be very busy. Acadia, Great Smoky Mountains, and Shenandoah can draw large crowds when fall colors peak, especially on weekends.

Is October too late to visit Yellowstone National Park?

October isn’t necessarily too late for Yellowstone, but I would plan a trip for earlier in the month if possible. Weather can change quickly, and roads, lodging, restaurants, and other park services begin closing as Yellowstone transitions into its winter season. Check current conditions and seasonal closures before your trip.

Which national parks are warm in October?

Saguaro, Joshua Tree, Zion, and Grand Canyon are good choices if you want warmer weather in October. Fall is an especially nice time to visit desert parks because temperatures are generally more comfortable for hiking and sightseeing than they are during the hottest part of summer.

Conclusion

October is one of the best times of year to explore America’s national parks. Cooler weather, smaller crowds, and beautiful fall scenery make it an ideal time for hiking and sightseeing.

Whether you’re looking for colorful foliage, mountain landscapes, or dramatic desert scenery, these are some of the best national parks to visit in October.
