Whether you’re a longtime local or a visitor passing through, witnessing the aspens in their autumn glory is one of the most memorable experiences you can have in Colorado. Below are the top spots around Boulder to soak in the brilliance of the season.

1. Peak to Peak Scenic Byway

No list is complete without the Peak to Peak. This iconic route, stretching from Estes Park through Nederland and down toward Black Hawk, is arguably the most breathtaking fall drive in the state. You’ll be surrounded by stands of glowing aspens with the Rockies towering in the background. Stop in Nederland for a coffee and a stroll—this quirky mountain town adds to the charm of the journey.

2. Brainard Lake Recreation Area

Tucked into the Indian Peaks Wilderness just west of Ward, Brainard Lake is a fall favorite. The mix of alpine lakes, rugged peaks, and groves of aspens creates a postcard-perfect backdrop. On a calm day, the golden reflections in the water double the beauty. Arrive early, as parking fills quickly during peak foliage weekends.

For a quieter escape just minutes from downtown Boulder, head to Betasso Preserve. The rolling trails offer a peaceful hike or mountain bike ride through patches of aspens. It’s close enough for an afternoon outing, yet still delivers those sought-after golden views without the crowds of higher-altitude spots.

4. Boulder Canyon Drive

The drive up Boulder Canyon toward Nederland offers vibrant color around nearly every bend. The canyon walls are dotted with aspens that catch the afternoon light, making the golds even more striking. Pull over at one of the roadside picnic areas to take photos and enjoy the crisp mountain air.

5. Caribou Ranch Open Space

Located near Nederland, Caribou Ranch is a mix of history and scenery. Old mining relics add character, but it’s the sweeping meadows framed by groves of aspens that steal the show in fall. Hike the Blue Bird Loop Trail for an easy trek through golden corridors and panoramic views.
