Seasons and Events Around Sunshine Canyon
Our growing library of guides to the Boulder area's seasons and recurring events, written from the canyon: what each one is, who runs it, what to plan around, and where to stay while it happens.
Leaf-Peeping Season
Fall Colors in Boulder and the Sunshine Canyon Foothills
Aspen gold up high, cottonwood red down low, and a maple avenue in town. The places we send our own guests, with the agency that manages each one and what to check before you go. Updated each fall.
Fall Color 2026: The Season Is On
This year's working guide: Brainard Lake timed entry, Chautauqua parking, the Peak to Peak drive, and how the color moves down the mountains toward town.
Race Weekends
Boulderthon 2026: The Morning After
The overall winners of the marathon, half, 10K and 5K, where to find every finisher time and race photo, and the 2027 date: September 26, with registration open.
Game Days
CU vs Kansas State: A Halloween Game Day at Folsom Field
The Buffs host Kansas State on Saturday, October 31, 2026 at Folsom Field. The date, the stadium, getting there, and where to put a group of twelve on a weekend Boulder fills up early.
Coming This Season
We are building this out week by week: Boulder race weekends, CU Buffs football home games at Folsom Field, and the festivals that fill the Boulder calendar. Each page is checked against the organizer's or agency's own site before it publishes. Check back, or tell us what you are planning a trip around and we will cover it next.
