Most people head to the mountains in the height of summer or the heart of ski season—but there’s a sweet spot in between that locals love just as much: shoulder season. Specifically, fall shoulder season, which runs from mid-September through mid-November, might be the most underrated time to enjoy Summit County.
You’ll find peaceful trails, golden aspens, cooler temps, and a slower pace all around. Fewer crowds, better deals, and beautiful views? Yes, please.
In short, shoulder season is the quiet period between peak travel times. In the mountains, that means:
Spring: April to early June (often called mud season thanks to melting snow and slushy trails)
Fall: Mid-September to mid-November (cool, colorful, and crisp)
While both have their perks, fall shoulder season is easier to plan around, with more stable weather, dry trails, and absolutely stunning foliage.
Hotels, rentals, and even restaurants often offer off-season specials. With fewer people around, you can enjoy popular spots without the usual crowds—or the long waits.
Fewer tourists means more of what makes this place special: friendly locals, unique shops, seasonal menus, and impromptu events you won’t find in the busy months.
While fall is a fantastic time to explore the mountains, it’s worth noting that some attractions and amenities take a break between the busy summer and winter seasons. Resorts like Breckenridge, Keystone, and Copper Mountain often close down summer operations—so ski runs aren’t open yet, and activities like mountain coasters or alpine slides are already wrapped up for the year. Even spots like the Frisco Adventure Center or Peak 8 Base Area may have limited hours or be closed entirely during this transitional window.
Many restaurants, shops, gear rentals, and tour operators also scale back or shut down temporarily for maintenance and staff time off. That said, core local services stay open, and you can often find great off-season deals if you know where to look. The key? Plan ahead. Whether you’re after a relaxing getaway or something more active, checking what’s open before you go will help you make the most of your fall visit.
What to Expect in Fall (Mid‑September – Mid‑November)
Weather: Crisp, sunny days with cool nights. Fall colors typically peak in late September, and by November, you might catch a light dusting of snow on the mountains.
Scenery: This is prime time for leaf-peeping. Golden aspens light up the hillsides, especially along scenic drives and hiking trails.
Vibe: Calm, quiet, and refreshingly uncrowded. Towns like Frisco, Breckenridge, and Dillon feel cozy and relaxed, with just enough going on to keep things interesting.
Though most resorts are closed in early fall, things change fast once the snow starts falling. Resorts like Keystone, Arapahoe Basin, and Loveland often race to be the first to open in Colorado—and sometimes even the country.
So, if you’re visiting in late October or early November, keep your eye on snow reports. You might just catch opening day turns before most people have even thought about waxing their skis.
Don’t miss Boreas Pass, Aspen Alley, or Sapphire Point for incredible views.
Lower-elevation hikes and bike rides are at their best. Dry trails + fall colors = perfect combo.
Explore the walkable downtowns of Frisco, Breckenridge, or Dillon—grab coffee, pop into boutiques, or settle in for a cozy dinner.
