San Diego's Favorite (and Nerdiest) Halloween Weekend Event

A 21+ Party | Friday, October 30, 6–11 PM

This Halloween weekend, journey through life and death across five floors of the Museum—from decomposition and fossilization to pollination, harvest, and the afterlife. Wicked fun awaits: pop-up science, bars on every level, and DJs that'll make you boo-gie the night away. Spooky bites and spirited drinks available for purchase. Read on to learn more about featured activities.

Leave the crowded bars behind, gather your favorite mortals, and wear a costume sure to impress in this world and beyond.
