Denver Zoo's Halloween institution returns with dated 2026 evenings now published: October 18, 19, 20, 25, 26, 27, and 31. Kids work trick-or-treat stations through the zoo grounds after regular hours while the animal buildings stay open into the evening.
Sessions run 4 to 8:30 PM, with Halloween night extending to 9 and offering a sensory-friendly 4:30 start. It is a ticketed event separate from daytime admission, and the near-Halloween nights sell out most years, so book the 31st early.
