The 9/11 Memorial at the World Trade Center has extended hours through December 31. Holiday hours are 10 AM to 8 PM daily, with the last entry to the site at 7 PM. After New Year’s Eve, the 9/11 Memorial returns to its regular winter hours, closing at 6 PM daily, with the last entry at 5 PM. You still need a ticket or reservation — and remember, please, that the 9/11 is FREE always free, and anybody who wants to sell you a ticket is a scam artist fraudster. The only exception to the word FREE is if you have paid for a group sightseeing tour that includes the 9/11 Memorial as one of the stops, and the tour operator provides tickets as part of the tour package. See the NYCOTC 9/11 Memorial Resource Page for all the information you need to reserve tickets, clear security and find a name.
