Belleville UFO Days

Every October, the small village of Belleville, Wisconsin, transforms into one of the state’s most unusual celebrations: UFO Days, an annual festival inspired by a series of reported UFO sightings that put the community on the map among alien enthusiasts and fans of strange Wisconsin history. The event traces its origins to January 1987, when Belleville police officer Glen Kazmar and other law enforcement officers reported seeing unusual lights hovering over the area. The sighting reportedly involved officers from multiple jurisdictions, including Dane County and Green County, and attracted national attention. Later sightings in the region continued the mystery, eventually inspiring Belleville’s annual UFO celebration.

Held each year on the last Saturday in October, UFO Days combines Wisconsin small-town festival traditions with a full dose of extraterrestrial weirdness. The centerpiece of the celebration is the UFO-themed parade through downtown Belleville, where costumed participants, alien-themed floats, unique vehicles, and Halloween characters take over the streets. Children are encouraged to dress in costume and collect candy from parade participants, creating a crossover between Halloween fun and Wisconsin UFO folklore. Beyond the parade, visitors can explore an outdoor marketplace, food vendors, live entertainment, and other community activities spread throughout the village.

More than just a UFO festival, Belleville UFO Days has become a celebration of local creativity, community pride, and the strange stories that make Wisconsin travel destinations memorable. Visitors can find alien-inspired decorations, themed activities, vendor market, and family-friendly attractions throughout the day, with local organizations and businesses participating in the festivities. Whether you believe the 1987 Belleville UFO sightings were evidence of something unexplained or simply enjoy Wisconsin’s collection of oddball roadside lore, UFO Days offers a uniquely Wisconsin experience where paranormal history, Halloween atmosphere, and small-town charm collide.
