Boulder’s biggest annual events & festivals

Farmers markets & recurring things to do in Boulder

The Boulder County Farmers Market is one of the best in the country, held on Pearl Street on weekends in season. Add the constant street performers on the Pearl Street Mall, CU Boulder events, and year-round trail and outdoor programming.

Boulder through the seasons

Spring and summer are packed — the Bolder Boulder, Creek Festival, Shakespeare Festival, and farmers markets; fall brings CU football and foliage hikes; and winter offers skiing nearby plus a full indoor arts calendar.

What to know about Boulder events

The Bolder Boulder and summer festivals draw big crowds downtown — bike or walk, as parking is tight. The Pearl Street Mall is the walkable event heart. Many events are free and outdoors.

What’s happening in Boulder this weekend

Printed event calendars go stale fast, and the best local happenings — pop-ups, block parties, last-minute shows — often never make the official listings. The most current, honest answer to “what’s going on this weekend?” comes from neighbors.

Where this fits in Boulder

The best events here are seasonal and neighborhood-driven, so timing is everything. The picks in this guide make the most sense once you know how Boulder is laid out. the Pearl Street Mall and the Chautauqua trails beneath the Flatirons sit at the center of where locals actually spend their time, so planning the local calendar around one of them rarely goes wrong. When you want something calmer, the Boulder Creek Path pulls you away from the busiest blocks, and the CU campus is the kind of spot regulars mention but visitors miss. Anchor your plan to one of those and the rest of the day in Boulder tends to fall into place.

Boulder events: the annual calendar

★ The BolderBOULDER is the big one. Colorado’s biggest Memorial Day tradition, the 10K runs on 25 May 2026 with over 52,000 participants and around 70,000 spectators. The finish is the part people remember: runners come into Folsom Field on the CU campus to a packed stadium, followed by a Memorial Day tribute and the elite professional race finish. If you are in Boulder that weekend, you are either running it or watching it – there is no third option.

Summer at Chautauqua. The Colorado Music Festival runs 9 July to 9 August 2026 in the historic 1898 Chautauqua Auditorium, with an orchestra of professional classical musicians from around the world. The Chautauqua Summer Concert Series runs June through August alongside it, mixing concerts, silent films, theatre, dance, forums and family events. See our Chautauqua guide.

The rest of the summer. Arts in the Park at the Bandshell runs June through August with Boulder Ballet, Boulder Symphony and Boulder Opera. The Frequent Flyers Aerial Dance Festival runs 26 July to 7 August 2026. Colorado Brazil Fest brings Brazilian music and dancing to the Bandshell on 6 to 8 August 2026. Boulder Taco Fest lands on 22 August 2026 with tacos, craft beer, tequila, lucha libre wrestling and live music. The Tulagi Music Festival runs 26 to 30 August 2026 with more than 600 artists across ten-plus stages.

Autumn. The Community Roots Art Festival (CRAFt) runs 19 to 20 September 2026, highlighting Black, Indigenous and brown self-identified artists.

Weekly, most of the year. The Boulder Farmers Market runs Saturdays 4 April to 21 November, 8am to 2pm and Wednesdays 6 May to 7 October, 3:30pm to 7:30pm on 13th Street. It is the most reliable recurring event in the city.

Boulder by season

Spring is unpredictable – heavy wet snow is possible well into May – but it brings the farmers market back on 4 April and builds toward the BolderBOULDER on 25 May.

Summer is peak Boulder: the Chautauqua concert season, the Bandshell programme, the festivals stacked through July and August, patios full, trails busy. It is also thunderstorm season – storms build over the Front Range through the afternoon, so outdoor events skew to mornings and evenings for good reason.

Autumn is arguably the best time to be here and the most underrated: the crowds thin as students settle into term, the light is extraordinary, the Flatirons look their best, and the trails are at their most comfortable.

Winter moves the calendar indoors. The trails stay open and are dramatically quieter, though shaded sections hold ice long after the streets clear. The ski resorts are within reach for day trips, and downtown carries the holiday programme.

Getting to events without the hassle

Two practical points that apply to almost everything on this page. Parking downtown on an event day is the main friction – use the paid garages rather than hunting for street spaces, or cycle in on the Boulder Creek Path, which runs right through the middle of the city.

For anything at Chautauqua in summer, the city runs a free Park-to-Park shuttle from the downtown bus station from late May through early September, which removes the Chautauqua parking problem entirely. On a concert night that is comfortably the smartest way in.

A final point on what the calendar tells you about this city. Boulder’s biggest annual event is a 10K road race that finishes in a football stadium, its summer centrepiece is a classical music festival in an 1898 wooden auditorium at the foot of a mountain, and its most reliable weekly event is a farmers market. That is an unusually accurate summary of the place: athletic, a bit intellectual, outdoors by default, and organised around things that happen every year rather than things that are new. If that appeals, the calendar here will keep you busy.

Free events, and where to find what is on

A surprising share of Boulder’s calendar costs nothing. The Bandshell programme through the summer, the street performers on the Pearl Street Mall, the farmers market itself, and the vast majority of the trail network are all free. Several of the festival events run free stages alongside ticketed ones, and the CU Boulder campus hosts public lectures, exhibitions and performances through term – the CU Art Museum is free to walk into. Our free things to do in Boulder guide collects the rest.

Because so much of this is community-run rather than commercially promoted, listings go stale fast and the smaller events often never get listed at all. That is precisely the gap residents fill.

Planning around the calendar

If you are visiting rather than living here, two dates dominate everything else. BolderBOULDER weekend at the end of May fills the city – accommodation is scarce, downtown is busy, and Folsom Field is the centre of gravity on race day. And the Colorado Music Festival through July and early August fills Chautauqua most evenings, which is wonderful if you have tickets and worth knowing about if you were planning a quiet sunset hike from that trailhead instead.

Outside those, Boulder’s events calendar is unusually easy to drop into. Most of the summer programme is free, outdoors and does not require booking, so checking what is on when you arrive works perfectly well here in a way it would not in a bigger city.
