Take a 1.5-hour walking tour of Ground Zero and the National September 11 Memorial, and gain insight into the September 11 attacks on the World Trade Center. A local guide shares firsthand stories of the event and its aftermath while you visit 9/11-related sites such as St Paul’s Chapel, the Fireman’s Memorial and the reflecting pools, an homage to the thousands of lives lost. You may also upgrade your tour to include a pre-reserved ticket to the One World Observatory.
