Colorado is gearing up for a vibrant St. Patrick’s Day season, offering a range of celebrations from large-scale parades to unique community events. Whether you’re seeking a lively pub crawl, a family-friendly fun run, or a charming puppy parade, the state has something to offer for everyone looking to celebrate the Irish holiday. From the bustling streets of Denver to the smaller communities of Boulder and Colorado Springs, festivities are planned throughout the weekend of March 14th and 15th, 2026.
The Denver St. Patrick’s Day Parade, billed as one of the largest west of the Mississippi, will kick off the weekend’s events on March 14th at 9:30 am, starting at 19th and Wynkoop Streets. This year’s theme, “Stars, Stripes and Shamrocks,” promises a patriotic and festive atmosphere. For those looking for a more active way to celebrate, the 38th annual Runnin’ of the Green, a popular 7k run/walk, takes place on March 8th at Washington Park. Participants can choose between a 7K race, a 2-mile “Leprechaun Leap,” and enjoy an Irish festival afterward.
Boulder’s Blend of Tradition and Whimsy
Boulder is embracing the spirit of St. Patrick’s Day with a diverse lineup of events. The city is known for hosting the “World’s Shortest St. Patrick’s Day Parade” on March 14th, a fun, block-long procession on 16th Street followed by a pub crawl. For animal lovers, the 3rd annual St. Patrick’s Puppy Parade & Costume Contest at Boulder Social on March 14th at 1pm is a must-attend. Located at 1600 38th Street, the event will feature a costume contest, photo opportunities, adoptable pups from POSO Dog Rescue, vendor booths, and a special puppy menu. A $10 donation per dog benefits POSO Dog Rescue, and attendees can enjoy a complimentary Social Beer with their donation.
