Best National Parks to Visit in October

October may just be the most underrated month to hit the national parks. The summer crowds have finally thinned out, temperatures are relatively cool, and in many of the parks, the trees are putting on their best show of the year!

If you’re trying to decide where to go this fall, these six parks are consistently some of the best national parks to visit in October — for the color, the weather, and the fact that you can actually find a parking spot.

Most of these picks are in the eastern half of the country, since October lines up with peak fall foliage season there, but there’s one western park on the list too, for a totally different reason: it’s finally cool enough to hike.

Let’s dive in so you can start planning your fall trip to the national parks!

1. Shenandoah National Park, Virginia

Shenandoah is only about 90 minutes from Washington, D.C., making it one of the most accessible fall-color trips on the East Coast. The mountains here put on a real show every October, and the park makes it easy to time your visit — rangers release weekly fall color reports during peak season so you know exactly where the color is best that week.

Plan Your Visit to Shenandoah National Park

• Location: Shenandoah National Park, Virginia, about 90 minutes from Washington, D.C.
• Peak Season: While open year-round, mid-October has peak foliage color, and Skyline Drive can close temporarily due to weather, so check the Shenandoah conditions page before you go.
• Where to Stay: Shenandoah has three in-park lodges — Skyland Resort, Big Meadows Lodge, and Lewis Mountain — plus four campgrounds (Mathews Arm, Big Meadows, Lewis Mountain, and Loft Mountain) right along Skyline Drive. See the NPS Plan Your Visit page for current lodging and camping details.
• Ash’s Recommended Activities: Bearfence Mountain Loop, driving Skyline Drive, and hiking to Dark Hollow Falls.
• How to Avoid the Crowds: Weekday visits during peak color will save you from the worst of the traffic on Skyline Drive.

2. Great Smoky Mountains National Park, Tennessee/North Carolina

This is actually the busiest park on the list — it’s actually the most visited national park in the country, by far! And it has beautiful fall foliage. With so many tree species packed into the park, the range of color here is hard to match anywhere else on this list. 

That popularity means you do need a plan if you want to enjoy the park without the crowds.

Plan Your Visit to Great Smoky Mountains National Park

• Location: Great Smoky Mountains National Park, Tennessee and North Carolina.
• Peak Season: The park is open year-round, but October is the single busiest month in the park because of foliage.
• Where to Stay: For an in-park stay, look at the campgrounds or the hike-in LeConte Lodge. For more amenities, base yourself in a gateway town like Gatlinburg, Townsend, or Cherokee. Our Where Should I Stay While Visiting the Great Smoky Mountains? article breaks down each option. 
• Ash’s Recommended Activities: Driving the Newfound Gap Road from Gatlinburg to Cherokee, with stops at the Campbell Overlook and Newfound Gap Overlook, and hiking to Grotto Falls through old-growth forest — the only waterfall in the park you can walk behind.
• How to Avoid the Crowds: Plan ahead. This is the single most important thing you can do for an October trip to the Smokies. If you want to see more about making the most of your trip while avoiding crowds, grab our Smoky Mountains National Park Itinerary here to get the tips!

3. Hot Springs National Park, Arkansas

Hot Springs flies under the radar compared to the rest of this list, but it’s a completely different kind of fall trip. The park is centered around natural hot springs, so you can soak in a bath or visit a spa, hike a few trails, and still get the payoff of cooler temperatures and lower humidity that October brings to Arkansas.

Plan Your Visit to Hot Springs National Park

• Location: Hot Springs National Park, Arkansas.
• Peak Season: While the park is open year-round, October brings noticeably cooler, less humid weather than summer.
• Where to Stay: The park sits right in the city of Hot Springs, so most visitors stay downtown near Bathhouse Row for easy walking access to the bathhouses, restaurants, and trails. Our Arkansas National Parks article covers where to stay and the best time to go in more detail. If you want to camp, we LOVE the in-park Gulpha Gorge Campground!
• Ash’s Recommended Activities: Strolling Bathhouse Row and touring the Fordyce Bathhouse (the park’s visitor center), soaking in a traditional bath at the historic Buckstaff Bathhouse, walking up to the Hot Water Cascade, and hiking the West Mountain Loop.
• How to Avoid the Crowds: This park sees a fraction of the visitors of the bigger-name parks on this list, so crowding is rarely an issue, even in October.

INSIDER TIP: 
You have to be at least 10 years old to soak in the Buckstaff Bathhouse. If you’re bringing kids on your trip, make sure you plan around it to avoid any surprises. We have taken our kids to hot springs, but we had to trade off taking care of them while the other adult went inside.  

4. Mammoth Cave National Park, Kentucky

Mammoth Cave is the longest known cave system on Earth, with more than 400 miles of mapped passageways, and October is one of the best times to enjoy it. The heavy summer crowds have died down by then, which means better availability for ranger-led cave tours. 

Above ground, the Green River Bluffs Trail is a great way to take in the fall colors along the river.

Plan Your Visit to Mammoth Cave National Park

• Location: Mammoth Cave National Park, Kentucky.
• Peak Season: The park is open year-round with daily cave tours, but keep in mind popular tours sell out, so book ahead!
• Where to Stay: Options include the in-park Lodge at Mammoth Cave and five NPS campgrounds, with Mammoth Cave Campground the most popular for its five-minute walk to the visitor center. See the NPS Camping page for details on each. 
• Ash’s Recommended Activities: The Extended Historic Tour — my personal favorite of all the cave tours — plus a hike on the Green River Bluffs Trail.
• How to Avoid the Crowds: Booking your cave tour in advance and visiting on a weekday will get you the smallest group sizes and the most availability.

INSIDER TIP: 
Mammoth Cave tour tickets go live on Recreation.gov up to 6 months before your visit, but the park doesn’t post the full tour schedule for a given month until 1 to 3 months before that date. 

If you’re planning an October trip, don’t wait until fall to check — popular tours (especially Domes and Dripstones and Frozen Niagara) can sell out weeks in advance! Start watching the Mammoth Cave tour reservations page on Recreation.gov starting in July or August, and book when your specific October dates go live. 

5. Acadia National Park, Maine

Acadia in October is prime leaf-peeping territory, with the added bonus of a coastline. It’s a great mix of hiking and biking, and Bar Harbor, right outside the park, is a genuinely charming town to base yourself in for a few days, making it one of the best national parks to visit in October. 

INSIDER TIP:
We have made the mistake of visiting Acadia a little too late in October! Restaurants, tours, shops, and hotels start closing down hard by mid-October as the season winds down. 

The caveat with going in early October? Sometimes the fall colors haven’t reached their peak yet. If you want to be in the park during peak fall colors later in the month, be aware that your amenity options will be very limited.

Plan Your Visit to Acadia National Park

• Location: Acadia National Park, Mount Desert Island, Maine.
• Peak Season: This park is open year-round, with peak months spanning from July to September. However, October brings cooler temperatures and the chance to see breathtaking foliage. 
• Where to Stay: There’s no lodging inside the park itself, so most visitors base themselves in Bar Harbor for easy access to the whole island. Our Where Should I Stay While Visiting Acadia National Park? article covers Bar Harbor and the quieter Schoodic Peninsula option. 
• Ash’s Recommended Activities: Watching sunrise from the summit of Cadillac Mountain, biking the 45 miles of car-free Carriage Roads, and walking the Bar Island Trail from Bar Harbor — a gravel land bridge that only appears at low tide.
• How to Avoid the Crowds: Visit in early October rather than late in the month — you’ll still get strong fall color with more services open and fewer visitors than the Smokies see during the same window. I have more information about this on the Acadia itinerary here!

6. Grand Canyon National Park, Arizona

Here it is, our western park. Grand Canyon is on the list, not for the leaves, but the temperature. Summer at the Grand Canyon can be brutally hot and genuinely dangerous for hiking. By October, conditions on the South Rim are much safer and more comfortable, and everything is open and accessible.

Plan Your Visit to Grand Canyon National Park

• Location: Grand Canyon National Park, Arizona.
• Peak Season: The South Rim is open year-round; October offers comfortable hiking temperatures compared to summer’s extreme heat.
• Where to Stay: Grand Canyon Village area. If you’d rather stay just outside, the town of Tusayan is the closest option. Our Where Should I Stay While Visiting the Grand Canyon? article walks through both. 
• Ash’s Recommended Activities: Hiking part of the Bright Angel Trail below the rim, then catching the free shuttle out to Hermits Rest — with Mohave Point as a great turnaround stop for the views along the way.
• How to Avoid the Crowds: Skip the summer altogether and plan your Grand Canyon trip for fall instead — you’ll trade brutal heat for comfortable hiking weather without the peak-season crowds.

Which Park Will You Visit First?
