This October, a new epic immersive theatrical Halloween adventure is overtaking Mystic Seaport Museum—and it’s unlike anything we’ve done before.
The Grampus set sail for a three-year whaling expedition in October 1826. After a brutal storm in the North Atlantic, rations ran out and a violent mutiny erupted on board. The Grampus went adrift. The ravenous crew was never heard from again, and there were thought to be no survivors.
Until tonight.
Two hundred years later, the Grampus has appeared at the seaport docks—and its rowdy, mutinous ghost whalers are looking for mischief, mayhem, and revenge. Follow the crew as they tell their tale and confront the supernatural forces that dragged them back in a wild, riveting seaside homecoming 200 years in the making.
Produced with New York-based Clockjack Productions, What Lurks Beneath: Ghost Ship unfolds across the Museum’s historic waterfront, where eerie stories and larger-than-life maritime characters create a mysterious world filled with strange encounters and secrets lurking beneath the surface.
Wander the waterfront at your own pace, following the stories and characters that draw you in. Around every corner, ghostly whalers, eerie tales, and unexpected encounters build the suspense. The experience is more spine-tingling than terrifying, letting the setting, the story, and your imagination do the haunting.
Spooky, swashbuckling, and full of surprises, What Lurks Beneath: Ghost Ship is a Halloween adventure recommended for ages 8 and up.
Feeling brave? Step inside the Ropewalk and Burrows House, where the mood grows darker and the story takes a spookier turn. These indoor scenes are optional, so you can choose just how far into the mystery you want to venture. Enter at your own risk.
What Lurks Beneath: Ghost Ship is a self-guided nightly theatrical experience that takes place across a large portion of the campus of Mystic Seaport Museum. Inspired by Edgar Allan Poe’s 1838 novel, “The Narrative of Arthur Gordon Pym of Nantucket,” the experience involves thrilling performances—live music, wild storytelling, unexpected sound effects, and staged swashbuckling. The audience will meet a colorful cast of characters, each telling terrifying tales from their misadventures on the high seas over the past two centuries!
The event is recommended for ages 8 and up; however, every family will have a different comfort level with Halloween experiences, so we encourage you to use your own judgment based on what you and your child enjoy. The Haunted Factory and Captain Barnard’s House are scarier (optional) indoor encounters, and are labeled as such with signage. There are NO jump scares in any part of the experience.
The experience has limited timed entries, so purchasing your tickets in advance is highly recommended in order to get the ticket entry time of your choosing. Attendees can stay until the end regardless of what time they enter.
