This Halloween weekend celebrate the BOO season on this zany journey around the museum.
Daily, Now - Nov 01, 2025. 4 p.m. to 11 p.m.
Come in costume and have a spooktacular time exploring our 100 room Museum — decorated special for Halloween. O Museum in The Mansion (also called The Secret Door Museum) has over 80 secret doors. Be warned secret doors are tricky to find — if you find 3 you are an above average sleuth.
Also includes a costume contest and a cash bar.
Online reservations required.
Bring your own shopping bags. Everything is for sale! Proceeds support programs at O Street Museum.
