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, which pay homage to the thousands of lives lost. You may also upgrade your tour to include a pre-reserved ticket to the One World Observatory.
