The best bars in Boulder Colorado are not where the out-of-town lists tell you they are, and August 2026 is a good time to say that out loud. The single most famous name in this city just closed, and every stale roundup on the internet is still sending people to a locked door on Baseline. So here is the honest version, built from bars that were verified open this month: cocktail dens, a Czech beer hall, two rooftops with Flatirons views, dives that have outlasted every trend, and a couple of rooms where the live music is the whole point. Boulder goes to bed earlier than Denver, sure, but the drinking here is better than its reputation.
Cocktails first
License No. 1 sits in the Hotel Boulderado's basement at 2115 13th St, and it pours under the same hard-liquor license first issued to this space in 1969, one of the first legal liquor licenses granted in Boulder after the city's long dry stretch. The room feels like it earned that history. It runs Wednesday and Thursday from 5pm to midnight, then Friday and Saturday from 5pm to 2am, so it doubles as one of the few genuinely late cocktail options downtown.
A few blocks over, The Bitter Bar at 835 Walnut St is the city's original craft-cocktail speakeasy. It has been open since 2009, runs Tuesday through Saturday from 5pm, and keeps a nightly happy hour from 5 to 7. If you want the drinks-are-the-reason experience without the basement, this is the one.
For a view with your gin, Corrida puts a Spanish steakhouse and its rooftop bar on the fourth floor at 1023 Walnut St, Suite 400. The signature move is a roving gin-and-tonic cart that comes to your table, with the Flatirons filling the western sky behind it. It is open daily, and it is the kind of place you take someone you are trying to impress.
Beer, properly
The Bohemian Biergarten at 2017 13th St is the loud, communal Czech hall a block off Pearl, complete with liters and long shared tables. It opens daily at 11:30am and runs a happy hour from 3 to 6. This is where you go with a group when nobody can agree on anything except that they want beer and space to talk over it.
Mountain Sun Pub & Brewery at 1535 Pearl St has been brewing its own on a six-barrel system since October 1993, and it is still, after all these years, the most Boulder room in Boulder: house beer poured daily. If you only have time for one brewpub, make it this one. If you want the full tour of what the city pours, our craft brewery guide goes deeper into the taprooms and production breweries.
The dives, and thank goodness for them
Sundown Saloon at 1136 Pearl St, tucked into the basement and known to every local simply as the Downer, has held the dive-bar line for more than thirty years. PBR, pool, shuffleboard, foosball, and exactly zero pretense. It runs daily from 3pm to 2am, which makes it both an afternoon hideout and a last-stop-of-the-night bar depending on your mood.
Out on the east side, the Outback Saloon at 3141 28th St has been open since April 1990. Five pool tables, skee-ball, and karaoke on Wednesday, Friday, and Saturday from 9pm to 1:30am. It is not trying to be charming and that is exactly the charm. Note the address, because it is on 28th, not 30th, and people mix that up.
Wine and rooftops
Postino WineCafe opened in May 2023 at 1468 Pearl St, Suite 110, right on the Pearl Street Mall, and it immediately became the easy answer for a low-stakes glass. Boutique wines, bruschetta boards, open daily until 10 or 11pm. When you cannot decide where to go, this is the safe yes.
Two spots stack their bars up top. Rosetta Hall at 1109 Walnut St runs eight kitchens and two craft-cocktail bars under one roof, with a rooftop that opens seasonally from April through November and stays late until 1am Thursday through Saturday. Avanti Food & Beverage at 1401 Pearl St is the food-hall rooftop that opened in October 2020, and it also delivers Flatirons views with your drink and a rotating cast of small kitchens if you get hungry.
For something more focused, West End Tavern at 926 Pearl St pairs a rooftop deck facing the Flatirons with one of the largest bourbon and whiskey selections in the Rocky Mountain West, plus 25 taps. It is the grown-up rooftop, the one that rewards a slow evening. Full rooftop rankings live in our rooftop guide.
Music, arcades, and late night
The Velvet Elk Lounge at 2037 13th St is a 220-capacity cocktail-and-live-music room with a real concert calendar, roughly a dozen shows booked across 2026. Check what is playing before you go, because the night changes completely depending on the act.
Press Play Bar at 1005 Pearl St covers the arcade-bar niche with 25 vintage cabinets, pinball, four-player Pac-Man, and skee-ball, open to 2am daily. It has its own listing in our business directory if you want hours and details. The Spotted James at 1911 11th St picks up the truly late shift as a neon bar and pool hall with live DJs and a dance floor, open nightly to 2am.
Up on the Hill, The Sink at 1165 13th St has been pouring for students since 1923. President Obama dropped in unannounced on April 24, 2012, and the order he placed became the menu's "POTUS Pie." It opens daily at 11am and is as much a Boulder landmark as a bar. If you are on the Hill and want the other student rite of passage, Half Fast Subs at 1215 13th St has reopened after an eight-month fire-repair closure and is still known for its personal pitchers of Long Islands.
A moment for the Dark Horse
The World Famous Dark Horse closed on March 14, 2026, after 51 years at 2922 Baseline Rd, taken by the Williams Village II redevelopment. Nearly every "best Boulder bars" list on the internet still sends people there, and those people are now standing in front of a demolition site. The owners have talked about a possible relocation to Louisville, but nothing in Boulder and nothing confirmed. Until it resurfaces, if it does, raise one at whichever room above suits your mood. For deal windows across town, our verified happy hours guide keeps the current times.
Frequently asked questions
Is the Dark Horse still open in Boulder?
No. The World Famous Dark Horse closed on March 14, 2026, after 51 years at 2922 Baseline Rd, when the site was cleared for the Williams Village II redevelopment. Its owners have discussed a possible relocation to Louisville, Colorado, but nothing has been confirmed and there is no Boulder location anymore. Most online bar lists still list it by mistake.
What are the best cocktail bars in Boulder?
License No. 1 in the Hotel Boulderado basement and The Bitter Bar on Walnut Street are the two originals worth building a night around. License No. 1 pours under a liquor license first issued in 1969, and The Bitter Bar has been Boulder's craft-cocktail speakeasy since 2009 with a nightly 5-to-7 happy hour. For a view, Corrida sends a gin-and-tonic cart around its Walnut Street rooftop.
Which Boulder bars have rooftops with Flatirons views?
Corrida on Walnut Street, Avanti and West End Tavern on Pearl Street, and Rosetta Hall on Walnut all put bars on their roofs facing the mountains. Rosetta's rooftop runs seasonally from April through November, and West End Tavern pairs its deck with one of the largest whiskey selections in the Rocky Mountain West. Our rooftop guide ranks them in full.
Where do you go for a good dive bar in Boulder?
Sundown Saloon, the basement bar at 1136 Pearl St that locals call the Downer, is the classic: PBR, pool, and shuffleboard, open daily until 2am. On the east side, the Outback Saloon at 3141 28th St has run since 1990 with five pool tables, skee-ball, and karaoke three nights a week. Neither is fancy, and that is the point.
What bars in Boulder are open late?
Several run until 2am, including License No. 1 on Friday and Saturday, Sundown Saloon and Press Play daily, and The Spotted James nightly. Rosetta Hall stays open until 1am Thursday through Saturday, and the Outback Saloon runs karaoke until 1:30am on weekend nights. Boulder closes earlier than Denver, but these are your late options.
Which Boulder bar did President Obama visit?
The Sink, at 1165 13th St on University Hill, has been open since 1923, and President Obama dropped in unannounced on April 24, 2012. The order he placed became a permanent menu item called the "POTUS Pie." It is one of the oldest and most storied bars in the city.
