What Lurks Beneath: A Halloween Experience

Wander through eerie indoor and outdoor spaces where ocean legends come alive October 17, 18, 24, 25, and 26, 2025. Timed entries at 6:00, 6:30, and 7:00 p.m. This limited-time experience blends Halloween thrills with maritime lore for all ages. Families and kids will love our fanciful performers, towering sea creatures, and ghostly projections. Make your own sea creature in our craft zone, then climb aboard the children’s mini-ship playscape for an imaginative adventure. Along the waterfront, explore the twilight ambiance of our historic seaport village, stop by Schaefer’s Spouter Tavern for Halloween-themed food and drinks, and gaze at massive Kraken tentacles climbing the rigging of the historic Charles W. Morgan.

Brave adults and older kids can join a haunting guided tour through the Museum’s shadowy corners. The town of Greenmanville has been overtaken—infested by creatures of the deep. You must escape the inhuman souls that crawl from the water, intent on turning you into one of their own. With a local as your guide, you’ll flee town and be swept into a tale guaranteed to make your blood run cold…with salt water. Come prepared to extinguish your lanterns and delve into what lurks beneath the waters of the Mystic. What Lurks Beneath: A Halloween Experience is sponsored in part by the State of Connecticut on behalf of the CHET 529 College Savings Program. We thank our community partner Power Posse Productions for their support of What Lurks Beneath.
