Ready to visit? Here's what to know before you go.

A ghoulish good time with a scientific twist.

Join us for a frighteningly fun day at the Museum! We’re opening the doors up just for our members, giving you the chance to explore your favorite exhibits, solve our sinister scavenger hunt and visit trick-or-treat stops! Creative and creepy costumes are encouraged, though face coverings are required for all guests age 2 and up.

See all the Boo Fest Member Day activities below.

Timed Museum entry tickets are required. Members are allowed to bring up to their admit number only. You’ll need to arrive at your ticketed entry time, but once inside, you are welcome to explore the Museum (and all its dark, haunted corridors) for as long as you’d like.

For those not comfortable visiting the Museum yet, we’ll help you throw the perfect shocking shindig at home! We’ll be sharing our favorite creepy coloring pages, spine-tingling science activities, ghoulish games and more.
