The Children's Museum of Denver at Marsico Campus lists Harvest Hoot on Friday, Oct 23, Saturday, Oct 24, and Sunday, Oct 25, 2026. The museum's what's-happening page says to dress in a favorite costume and enjoy fall activities. Museum hours on that site are 9 AM to 4 PM.
The Denver Gazette's Oct 3, 2026 story says the weekend includes the Monster Mash Circus, Adventure Forest, sensory sand potions, carnival games, spooky stuffies, and a cranberry bog. It says the activities are included with museum admission, members are free, advance tickets are not available, and tickets are bought at the museum. Costumes must be family-friendly.
This is on the family calendar because the museum is for kids. It is not filed as a free day. General admission still applies.
