Custom-built for the Magnificent Mile, the Iceberg Trail is the result of three years of research and development. Each of the six icebergs is equipped with a state-of-the-art, human-powered mechanism that activates unique light displays and custom music. What makes this experience truly special is that each iceberg accumulates energy, offering users up to 12 minutes of experience after just 20 seconds of interaction. Together, the six icebergs are bringing much-needed light and laughter to Chicago during the cold winter months.
