Take an after-lunch stroll on the Aqueduct Trail. Meet at Irvington’s Town Hall at 85 Main Street, less than ½ mile east up Main Street from the Irvington Metro-North train station (free parking). Visit the Tiffany Reading Room, one of a handful of Tiffany interiors. Meander north on the Old Croton Aqueduct Trail (which intersects with Main Street) to Lyndhurst and back, admiring architectural landmarks, including the skeletal remains of a Lord & Burnham conservatory, and Hudson River views. Learn the history of the Old Croton Aqueduct and the millionaires who lived along the trail in the 1800’s. On the return trip, you might stop to tour Jay Gould’s Lyndhurst or Washington Irving’s Sunnyside mansion (paid guided tours are available at both). When you return to Main Street, if you would like to see more, you may choose to continue your walk south (and back) on the Aqueduct to view more historic mansions. (From Metro-North Hudson Line Irvington Train Station, a 5-10-minute uphill walk). Inquiries: Sara Kelsey, email@example.com, 646-303-1448.
