Although Manassa has only nearly 1,000 residents, during its annual Manassa Pioneer Days, the population soars to around 10,000. It’s one of the oldest festivals in Colorado.
It will be celebrated from Thursday to Sunday on July 17th to 19th, 2025. Generations from across the San Luis Valley and tourists from all over descend on sleepy Manassa for one of the best Western heritage festivals around.

The pioneers started the annual tradition. Events include carnival rides, a main street parade, Miss Pioneer princesses, demolition derby, fair food, an old-time bandstand, and rodeo competitions. The parade is so prized that it goes up and down Main Street two times.
