The National 9/11 Memorial & Museum
The fourth stop is the World Trade Center, as we visit the 9/11 Memorial. The tour does not include entry into the 9/11 Museum, but visitors can walk the grounds of the Memorial, visit the waterfalls of "Reflecting Absence," (the footprints of where the original twin towers stood), and see the Survivor Tree that stood up to the destruction of 9/11.
