The Sagamore Resort

The Sagamore first opened in 1883 on a Lake George island as an exclusive resort for the wealthy. Two fires later, the current building went up in the 1920s. It's named after a character from "The Last of the Mohicans" and sits on land once believed to be a Native burial ground.

Multiple spirits haunt the Sagamore. Lillian, a woman in a pinkish-brown dress with lace details, stands on the porch gazing at the lake -- still waiting for the boats she loved during her 1880s visits. "Walter," a portly man, materializes in elevators. An employee once bumped into him right before he appeared.

In Mr. Brown's restaurant, a tall woman in white evening attire with sandy blonde hair walked up to a prep cook, spoke to him, passed straight through him, and vanished. The cook quit immediately. A ghost boy, killed by a car in the 1950s while chasing golf balls to resell, throws balls at golfers on the course while laughing. Guests also report silverware moving on its own and sharp temperature drops in the dining room.
