A few years ago I made the trip to Crested Butte during peak fall color, and it was one of those Colorado moments you don’t forget. The mountains were covered in brilliant shades of gold, the air was crisp, and it reminded me why I love living here. The only problem? Everyone else wants to see the leaves change in CO too.
The short answer: most Colorado aspen peak in the second half of September. Guanella, Kenosha and Boreas Pass run from about September 15 into the first week of October. Kebler Pass and Crested Butte hold on later, into mid-October. The foothills right behind Littleton finish last, into late October, and that late color is scrub oak rather than aspen. Deer Creek is the closest at 23 minutes from Littleton.
Article Summary
- Colorado’s fall color runs from mid-September to late October, not on one statewide date, and most aspen destinations peak in the second half of September.
- Deer Creek Canyon Park is the closest color to Littleton at 23 minutes, and the foothills parks are also the last to peak.
- Book lodging now. Weekend nights in Crested Butte, Steamboat, and Grand Lake go first, and midweek is not far behind.
- Maroon Bells and Rocky Mountain National Park require reservations in fall. Golden Gate Canyon needs a state parks pass. Nothing else on this list requires either.
The best campgrounds fill early and the cabins go months out. That’s why I post this before the leaves turn. If you are planning to see the leaves change in CO, book the lodging first, then pick the weekend.
When Do the Leaves Change in CO?
Colorado’s aspens don’t turn on one date. Most aspen destinations peak in the second half of September. Elevation drives a lot of it, but not all of it: Kebler Pass sits above 10,000 feet and still peaks into mid-October, while the Peak to Peak Byway, a couple of thousand feet lower, is done by the end of September. The foothills right behind Littleton close out the season in late October. In short, peak color is the week or two when most aspens in one area have turned gold. After that, wind and frost strip them. One thing worth knowing: aspen gold is a high-country thing. Down in the foothills behind Littleton the late color is scrub oak, reds and rust rather than gold.
These are windows, not dates. Rainfall, drought, and an early cold snap all move them, sometimes by a week. If you want the timing broken out by elevation band rather than by destination, I put that in fall colors near Denver.
How Far Is Each Spot from Littleton?

Where Can I See Fall Colors Near Denver in One Day?
One of the best parts about living in Littleton is how close the good scenery is. Six of these are inside an hour and a half. Here are a few of my favorite day trips.
Guanella Pass
1 hr 30 min from Littleton, 60 miles. Aspen groves the whole way up, with Mount Bierstadt sitting right there. Mid-September into the first week of October is the window to aim for. Leave time to wander Georgetown while you’re up there.
Kenosha Pass
1 hr 19 min from Littleton, 57 miles. If you’ve ever seen a postcard of Colorado in the fall, there’s a good chance it was taken here. The Colorado Trail crosses the pass, making it a great destination whether you’re looking for a scenic drive or a short hike. The Forest Service warns that the trailhead gets very busy with leaf peepers, and tells you to use extra caution along the Highway 285 corridor. That means cars parked on the shoulder of a mountain highway. Go early on a weekend, or better, go midweek. At right around 10,000 feet, it peaks late September into the first week of October. There’s no drinking water at the site, so bring your own.
Golden Gate Canyon State Park
54 min from Littleton, 36 miles. You get a real hike out of it and you’re still home by mid-afternoon. It holds color from late September into the third week of October, about a week behind the high passes, so it is a good backup once they have dropped. It’s a Colorado state park, so you’ll need a vehicle pass at the entrance.
Mount Falcon Park
42 min from Littleton, 19 miles. You don’t have to drive far for this one. Mount Falcon has good hiking, colorful foothills, and long views back toward Denver. Here’s the part most people get wrong: there are two ways in. The West trailhead on Mount Falcon Road in Indian Hills drops you near the top, so the walk to the views stays short and nearly flat. The Morrison trailhead on Vine Street puts the Castle Trail in front of you instead, and that one climbs 2,000 feet. Same park, completely different afternoon. Mount Falcon and Deer Creek Canyon turn last around here, which makes them what I point people to when the passes are already bare. Color holds at Mount Falcon from the first of October into the third week. Matthews/Winters Park is a few minutes north on the same road if you want to make a longer day of it.
Deer Creek Canyon Park
23 min from Littleton, 12 miles. The closest color to town, and most people drive past it on their way to the mountains. About a third of the park burned in the 2024 Quarry Fire and you will see it, so aim for the unburned side. Same late schedule as Mount Falcon, which makes it worth a morning even in the third week of October. If you want more trail options on that side of town, I put together a guide to the best hikes and trails in Ken Caryl.
Peak to Peak Scenic Byway
1 hr 2 min to Black Hawk, 43 miles. Colorado’s oldest scenic byway runs from Estes Park down to Black Hawk, mixing pine forest and aspen with wide Front Range views. Peak runs mid- to late September, and because the byway crosses several elevation bands you see different stages of the season on one drive. One thing worth knowing: that hour gets you to the south end at Black Hawk. Driving the byway itself is most of a day.
Where to See the Leaves Change in CO on a Weekend Trip
If you have a little more time, these are worth a full weekend.
Kebler Pass and Crested Butte
4 hr 10 min from Littleton, 183 miles. This is still one of my favorite Colorado fall memories. The combination of historic downtown, mountain scenery, and endless golden aspens makes it feel almost unreal. Kebler holds one of Colorado’s largest aspen stands, and it peaks later than you would expect for its elevation, from late September into mid-October. The color runs for miles along the road instead of showing up in patches. Stop by the Secret Stash on Elk Avenue and try the Notorious F.I.G. while you’re in town. Kebler Pass Road is unpaved and it closes for the winter. In dry weather most passenger cars handle it fine, but check conditions before you go. If you’re headed that way, don’t wait to reserve lodging.
Trail Ridge Road and Grand Lake
2 hr 17 min to Grand Lake, 106 miles. Trail Ridge crests at 12,183 feet, well above treeline. The tundra up top turns first, while the aspens near Grand Lake, nearly four thousand feet below, are still green. Fall color and elk bugling season overlap here. The aspens down around Grand Lake peak in the second half of September. Two things to plan around: the park runs a timed entry permit system that ends in mid-October, and Trail Ridge closes for the winter when the snow wins. The Park Service says mid-October, but the average is closer to October 23 and it has stayed open into November, so check the road status page rather than the calendar.
Steamboat Springs
3 hr 5 min from Littleton, 160 miles. Everybody knows Steamboat for skiing. Fall is the quieter trip. Hiking trails are emptier, temperatures are comfortable, and the aspen viewing is up at Buffalo Pass rather than in town. Peak there is mid- to late September.
Maroon Bells
3 hr 35 min to Aspen Highlands, 168 miles over Independence Pass, or 3 hr 56 min and 204 miles on I-70 when the pass is closed. The most photographed peaks in Colorado, with gold aspens reflecting in Maroon Lake. Peak here is the third and fourth weeks of September. Plan this one properly. From late May through mid-October, October 18 in 2026, the Forest Service closes the road to inbound private cars between 8 a.m. and 5 p.m. During those hours, the shuttle from Aspen Highlands is your only way in. To drive yourself you need a parking reservation and an arrival before 8 a.m. or after 5 p.m. Independence Pass is the short way and it closes for the winter. Book either through Visit Maroon Bells, and check the current dates.
Boreas Pass
1 hr 46 min to Breckenridge, 87 miles. A historic railroad grade above Breckenridge. It’s a dirt road, but a smooth one. In fact it’s fine for a passenger car when dry. The best color runs the last two weeks of September and the first week of October.
Multi-Day Drives Worth the Planning
These two need real time off, but they are the ones people fly in for.
San Juan Skyway
A loop of roughly 235 miles through Durango, Silverton, Ouray, and Ridgway, with a spur up to Telluride. This is a three-day trip from Littleton, not a weekend one. Color peaks here at the end of September into early October, a little later than most of the state. The valleys are still gold while the peaks above them already have snow on top.
Dallas Divide
Near Ridgway, and the classic postcard view of the Sneffels Range. Same timing as the rest of the San Juans, the end of September into early October. This is the one photographers plan trips around, and it pairs with the San Juan Skyway rather than standing alone.
A Few Local Tips
- Book now. Campgrounds, cabins, and vacation rentals in mountain towns disappear quickly once September arrives.
- Weekdays are worth it. If your schedule allows, you’ll enjoy fewer crowds and easier parking.
- Pack layers. A sunny afternoon in Littleton can turn into a chilly mountain morning or evening.
- Fill your gas tank before heading into the mountains. It’s usually less expensive, and you’ll have more options.
- Don’t chase the perfect Instagram photo. Every year is different. Some of my favorite memories have come from places that weren’t at peak color but were simply beautiful because I was there to enjoy them.
One More Reason I Love Living Here
I’ve lived in Littleton for 27 years, and one of my favorite things about calling this community home is how easy it is to escape into the mountains. You can leave after breakfast, spend the day hiking through golden aspen groves, enjoy lunch in a mountain town, and still be home in time for dinner. That’s something I never take for granted. If you’re weighing a move toward the foothills, the current Littleton listings are a good place to start.
Frequently Asked Questions
It depends on the area, not one statewide date. Most aspen destinations peak in the second half of September. Guanella, Kenosha and Boreas Pass run from about September 15 into the first week of October, Kebler Pass and Crested Butte hold on into mid-October, and the Littleton foothills come last, around October 1 to 23, with scrub oak rather than aspen. The chart above shows each window.
Golden Gate Canyon State Park, Mount Falcon Park, Guanella Pass, and Kenosha Pass are all reachable in a single day from Littleton or Denver. Deer Creek Canyon Park involves the least driving at 23 minutes, with Mount Falcon Park next at 42 minutes.
Usually yes. From late May through mid-October, October 18 in 2026, the Maroon Bells Scenic Area is closed to inbound private vehicles between 8 a.m. and 5 p.m. During those hours the only way in is the shuttle from Aspen Highlands. If you want to drive yourself you need a parking reservation and you have to arrive before 8 a.m. or after 5 p.m. Book either at visitmaroonbells.com, and check the current dates because they shift each year.
Yes, usually. Rocky Mountain National Park runs a timed entry permit system that ends in mid-October, October 12 in 2026 for the standard permit and October 18 for the Bear Lake Road one, booked on recreation.gov. The dates and hours change every year, so check before you drive up to Grand Lake or Estes Park.
August. Campgrounds, cabins, and vacation rentals in mountain towns such as Crested Butte, Steamboat Springs, and Grand Lake are typically gone before September starts, and weekend nights go first.
The Littleton foothills. Mount Falcon Park and Deer Creek Canyon run about two weeks behind the high passes, into late October, and their late color is scrub oak rather than aspen. They are the fallback if you miss the mountains.
Whenever you go to see the leaves change in CO, I hope you get out and enjoy it. Fall is the best few weeks we get. And if you miss the passes, don’t write off the season. Mount Falcon and Deer Creek are still turning when the high country is bare.
