Overview Tennyson Fall Fest is a free one-day October street fair on Tennyson Street in northwest Denver, and it opens with a pet parade and costume contest down the closed street. More than 100 local vendors set up between West 41st and West 43rd Avenue, beside the street's own restaurants and food trucks, and live music runs until 6. Team Player Productions produces it for the Tennyson Berkeley Business Association as the fall counterpart to the Tennyson Street Fair in July. Team Player, based in Golden, has produced events since 1996, among them the Boulder Creek Festival and the Vail and Breckenridge Wine Classics. On site The 2026 day ran 10 a.m. to 6 p.m. The pet parade took the first hour, Ohana Yoga and Barre taught a free class at 11, and three local bands followed: Swift Current, The Midnight Soulbirds and AFB, who closed the afternoon. A Wax Trax DJ pop-up, a photo booth, inflatables and kids' activities ran all day. Beer and spirits are sold at several points along the street, and a water refill station sits outside Berkeley Untapped. The footprint is mostly pavement and sidewalk, with some grass and uneven ground. Audience Leashed dogs are welcome and get the opening hour to themselves. The festival has no parking lots of its own and marks out designated bike parking. Brand presence Sponsors on the 2026 festival site included Frank Azar, Crispy Cocktails, Polar and Mountain Safe Exteriors. Sponsorships are built to order rather than sold from fixed tiers. The festival bars unauthorized vending, sampling and petitioning, so product sampling on the street goes through the organizers.
