Captain Grant's, 1754, Preston
Captain Grant’s 1754 — Preston
Tucked away in Preston, Connecticut, Captain Grant’s 1754 is a historic bed and breakfast housed in a home dating back to 1754. The property offers guests the chance to stay surrounded by centuries of New England history, but according to reports from visitors, there may be more than history occupying the house.
Guests have reported hearing footsteps throughout the property, along with disembodied voices and other unexplained sounds. Some visitors describe the spirits associated with Captain Grant’s as friendly, creating an atmosphere that is more intriguing than frightening.
The property has also gained attention from paranormal television, including an appearance on 28 Days Haunted. For those interested in combining a historic getaway with a taste of the paranormal, Captain Grant’s offers an experience unlike an ordinary bed and breakfast.
Captain Daniel Packer Inne, Mystic
Captain Daniel Packer Inne — Mystic
Along the Mystic River, the Captain Daniel Packer Inne is known for its historic atmosphere, cozy pub setting, and classic New England character. But according to local stories, the building has another side that diners and staff have noticed over the years.
Reports of unusual activity include glasses mysteriously falling, unexplained noises, and voices heard throughout the building. One of the most well-known stories involves Ada, a young girl who is said to haunt the inn.
According to the legend, Ada was seven years old when she died and is believed to remain at the property. Some stories describe her as a friendly presence, particularly around children.
Whether you visit for dinner, the history, or the possibility of encountering something unexplained, the Captain Daniel Packer Inne has a story that adds another layer to Mystic’s historic waterfront.
Seaside Sanatorium — Waterford
Overlooking Long Island Sound in Waterford, the former Seaside Sanatorium has a history that is both fascinating and unsettling.
The facility originally served as a hospital for children with tuberculosis before later being used as a geriatric and mental health facility. Today, the former hospital buildings are abandoned, while the surrounding property is part of Seaside State Park.
The abandoned buildings are not open for visitors, but the surrounding state park provides striking views of Long Island Sound and a chance to experience the history of the area from a safe and legal vantage point.
Over the years, stories surrounding the property have included reports of apparitions, shadowy figures, unexplained voices, and other paranormal experiences. Its abandoned structures and history have helped make Seaside one of the most talked-about locations along Connecticut’s haunted trail.
