Las Animas celebrates an annual Santa Fe Trail Day, a celebration of the pioneers and traders who used this trail. This local holiday is the oldest student council-sponsored event in the US. The Las Animas High School Student Council organizes the day, with assistance from the Bent County Chamber of Commerce. Festivities have included a parade, a costume contest, square dancing, a demolition derby, and a traditional "Ranchburger" lunch, as well as many other activities.
