Chicago Loop Self Guided Ghosts Gangsters and Secrets Tour

Start at the memorial to the SS Eastland, which rolled over at its dock on the Chicago River in July 1915 and killed 844 people, most of them factory workers and their families heading to a company picnic. Your audio guide tells how it happened just feet from shore, and why the river has never quite let it go.

Viewed from outside. The tour does not go in. Walk into Couch Place, the narrow alley behind the theater that stands on the site of the Iroquois Theater. During the 1903 fire there, more than 600 people died, many of them trapped behind locked exits, and the alley earned the name Death Alley.

The Palmer House opened in 1871 and burned to the ground just 13 days later in the Great Chicago Fire. Rebuilt and still operating today, it is one of the oldest hotels in the country, and your audio guide shares the ghost stories guests and staff still tell. You can step inside to see the famous lobby ceiling.

Stand outside the Rookery, an 1888 masterpiece on LaSalle Street said to be haunted by its own brilliant architect, John Root, who died young just a few years after it opened. Your audio guide tells his story and why some believe he never left.

Viewed from outside. The tour does not go in. Look up at Willis Tower, once the tallest building in the world. Your audio guide explores the fear of stepping onto the glass Ledge, 1,353 feet above the street, and the day the Ledge cracked under visitors' feet. Going up to the Skydeck is optional and ticketed separately.
