An evening at the museum for guests 21+
21+ Only | A valid government-issued ID is required for entry for all attendees
OMSI After Dark: Bogs & Swamps is our usual April Earth Day theme, with a marshy twist. Vendors and lectures will revolve around the world’s bogs, swamps, marshes, and wetlands – so come embrace Rot Girl Spring with us.
Unfamiliar with the event? OMSI After Dark is for guests 21 and over, where you can have a drink and wander the exhibits after hours. Interact with hands-on science experiments, live performances, local educational groups, lectures, food and beverage samplers, and more. Each event has a different theme, which means a new set of people and entertainment to engage with each month!
