This tour is offered by Viator, a Time Out partner.
If you always turn up to late to the High Line's free tours (visit thehighline.org/tours for more information), or if it doesn't fit in with your schedule, try this two-hour guided walking tour which begins in the Meatpacking District then traverses the length of the nearly 1.5 miles of elevated park. Stops include the White Star Pier, where the survivors of Titanic disembarked, and the old Nabisco factory, where the Oreo Cookie was invented.
