Golden Aspens and Alpine Lakes: Driving Guanella Pass in Fall

If you’re searching for golden aspens, reflective alpine lakes, and sweeping mountain views, Guanella Pass in fall is hard to beat. Just an hour from Denver, this high-country scenic byway is one of our favorite places to see fall colors in Colorado. The 22-mile drive winds from the historic mountain town of Georgetown to Grant, passing brilliant stands of golden aspens, quiet creeks, alpine lakes, and plenty of scenic overlooks along the way. You can simply enjoy the Guanella Pass fall colors from the road, or stop for photos, a lakeside picnic, or a hike into the surrounding mountains.

We’ve driven Guanella Pass during peak fall color and found that knowing where to stop—and when to go—makes a big difference, especially during the busy leaf-peeping season. Here’s our local guide to the best stops, hikes, photo spots, and practical tips for planning a Guanella Pass fall road trip.

When to See Guanella Pass Fall Colors

Late September through the beginning of October is typically the best time to see the fall colors on Guanella Pass. The timing varies year to year, depending on weather conditions. Check local news sites and fall color sites for the latest information before you head out. Be sure to check the weather forecast and road conditions too, there can be snow this time of year.

Pro Tip: Plan your visit midweek, starting early in the day for the best light and less traffic on the road.

Tips for Experiencing Guanella Pass Fall Colors

The Guanella Pass fall colors drive is one of the most popular leaf peeping routes in Colorado, because of its proximity to Denver. Here are some tips to enjoying Guanella Pass without the crowds.

• Avoid weekends: The pass can get so busy on peak weekends that you can’t find parking. In extreme cases, officials close the road except to locals until the road becomes less congested.
• Go early or late: Start your drive before 9:00 am or after 3:00 pm on weekdays to avoid traffic and secure parking.
• Bypass I-70 construction: Check traffic before you go on COTrip.org. I-70 construction delays often start around 9:00 AM—beat them by leaving early, or plan to spend the night in Georgetown before you go.
• Drive one way: Begin off of I-70 in Georgetown, end in Grant, and take Highway 285 back to Denver.
• Pack food and water: Bring snacks (or lunch) and extra water—there are no water sources or food on the pass. There are beautiful spots for a picnic en route.
• Allow time: While you can complete the drive with no stops in under an hour, it’s better to plan 2-4 hours for the full drive with scenic stops, hikes, and photos.
• Follow parking rules: Parking is very clearly marked and it is heavily enforced. Do not park outside designated areas. This can result in both fines as well as towing of your car.

Georgetown Visitor Center

Start your trip in Georgetown, where the Gateway Visitor Center offers restrooms, water refill stations, and maps. For those looking to enjoy a coffee before your drive, we’d recommend Mountain Mama’s or Nara Visa Coffee.

Best Stops for Guanella Pass Fall Colors

Scenic Overlooks Georgetown to Summit

There are a handful of marked pull-offs as you ascend the pass. Be sure to stop at as many of these as you have time for to take in the views (and take photos).

One of the earliest stops has beautiful views over the town of Georgetown, which is even more lovely with the aspens framing the photo. The town sits in the shadow of the mountains early in the morning (see in photo below). Capturing this shot late afternoon is typically a better option.

Silverdale Interpretive Trail

One of the first main parking areas is for the Silverdale Interpretive Trail. This historic area has interpretive signs, short hikes, and a port-a-potty. It’s also a great spot to see Guanella Pass fall colors mixed with mining history. For an easy trail through the aspens and crossing South Clear Creek, try the Sporting Times trail. It has QR codes that you can scan for historical information about the area. If you connect to the moderate Railbed Trail, you’ll come across the remains of the Silverdale Mining Town.

Pro Tip: If you are visiting Colorado in December, the Sporting Times trail is one of our go-to spots for Christmas tree cutting. Georgetown issues permits for tree cutting, which helps with their wildfire mitigation efforts.

Clear Lake Picnic Area

One of the top stops for fall colors on Guanella Pass is the Clear Lake picnic area. It’s perfect for photos or for a picnic by the lake, as the name implies. As you exit at the Clear Lake picnic area turn off, stay left at the fork to reach the lake. There are picnic tables and pit toilets available near the parking lots. Walk down to the lakeshore to capture the golden aspens reflecting in the water.

Cabin Creek Hydro Plant

The pull-off for the Cabin Creek Hydro plant parking area may not sound like an ideal spot to stop, but the views are simply stunning. Take the time to read up on the historic high-altitude, clean-energy water plant, which Xcel Energy is renovating, supporting their commitment to a 2050 goal of carbon free electricity.

Guanella Pass Summit

At 11,669 feet (3,500+ meters), Guanella Pass’ summit has stunning alpine views. From here, many take the trail to Square Top Lakes, a 4.9 mile easy-moderate hike through tundra and golden meadows.

The Mount Bierstadt Trailhead is a classic hike from the east side of the summit, leading 7.2 miles challenging miles to the summit of one of Colorado’s 14’ers (14,000 foot+ elevation mountains).

Pro Tip: Check the weather forecast carefully before you go. Even if it is warm in Denver, it can be much cooler (and often windy) at the summit. The hikes from the summit are quite exposed to both the sun and wind.

Scenic Overlooks on the Descent

As you begin to continue past the summit toward Grant, take the time to stop at the marked overlooks. These offer broad views of the large aspen groves and fall colors across Guanella Pass,

Burning Bear & Abyss Trailheads

As you continue down towards Grant, you’ll see the very popular Burning Bear and Abyss Trailheads. While we had no issues finding parking anywhere else on Guanella Pass on a recent weekday visit, we found one of the last spots for the Abyss Trailhead. Almost as many people were taking fall portraits here as were hiking on the trails. If you don’t find a parking spot right away, just wait a few minutes. Spots seem to open up fairly quickly here.

There are 2 primary trails to choose from here. In both cases, they are out and back trails, and you can choose to do just a portion of the trail, then turn back around.

• Abyss Trail: a hard, 11.9 mile hike up to Abyss Lake.
• Burning Bear Trail: a moderate, 7.5 mile trail.

If you prefer not to hike, there are typically find beautiful fall colors right at or near the parking area.

Whiteside Gulch & Geneva Creek

These quieter stops are perfect for picnics along Geneva Creek, which winds through bright stands of aspen in fall. These spots are very popular for those who come out to take portraits with Guanella’s fall colors in the background.

Lunch Spots After Driving Guanella Pass

After finishing your Guanella Pass drive, you can either re-trace your steps or make a loop back to Denver by taking US-285. As you come off the pass, follow signs for Denver. For those who didn't stop for a picnic lunch along the way, you'll find a number of options in Grant and Bailey, along US-285.

• 2 Dads Eatery and Taproom (Bailey): Known for their pizzas, wings, sandwiches.
• The Shaggy Sheep (Grant): A local favorite named after Colorado's Bighorn Sheep is open for breakfast and lunch. For lunch, enjoy burgers, salads, and Colorado craft beers.

Where to Stay Near Guanella Pass

While many visitors do Guanella Pass as a day trip from Denver, staying overnight nearby makes it easier to enjoy the drive at a more relaxed pace. In Georgetown, you’ll find charming lodging options like the Rose Street Bed & Breakfast, a cozy inn within walking distance of downtown shops and restaurants.

Final Thoughts on Guanella Pass Fall Colors

Guanella Pass fall colors are not to be missed, whether you're an avid photographer, hiker, or simply a casual leaf-peeper. With smart planning—visiting on a weekday, starting early, packing lunch, and pacing your stops—you’ll enjoy one of Colorado’s most iconic autumn drives.
