Interior of the Old Croton Aqueduct waste water weir at Ossining, New York.

The Old Croton Aqueduct, New York City’s original water supply, runs from, Croton-on-Hudson into the Bronx and Manhattan, passing through Sleepy Hollow and Tarrytown. For most of its length, the Aqueduct is a horseshoe-shaped brick tunnel 8.5 feet high by 7.5 feet wide, set on a stone foundation and protected with an earthen cover and stone facing at embankment walls. Don’t miss this rare chance to enter one of the historic water diversion chamber to view the tunnel itself!

This is a free, easy, 2-hour tour operated by Friends of the Old Croton Aqueduct. Meet at the benches in front of the Joseph Caputo Center, which is located at 95 Broadway, Ossining, NY 10562, just west of Rte. 9/Highland Ave. at the junction of Croton Ave. (Rte. 133) (from Metro-North Ossining Train Station by taxi or 15-minute uphill walk). (Parking lots nearby) After a brief walk, descend into the Weir in Ossining and explore the original 1842 brick water tunnel and learn its history.

Required: pre-registration (limited number); bring masks, and social distancing. Walk will be rescheduled if weather does not cooperate.
