The New London Maritime Society will be hosting tours to Ledge Lighthouse with The Atlantic Paranormal Society as part of a fundraiser for the Maritime Society Saturday. The tour runs from 1 to 4 p.m. and departs from the floating dock next to New London’s City Pier on a Project Oceanology boat.

Paranormal Society lead investigator Traci Boiselle and investigator Cody DesBiens will lead both tours and plan to cover “basic theories of the paranormal and why hauntings might occur,” while also explaining the methods and equipment used by investigators to aid in their paranormal research.

The Atlantic Paranormal Society is the same group associated with the long-running “Ghost Hunters” television show which aired on the Syfy Channel from 2004 to 2016.
