Harbor Line Architecture Tours

The New York chapter of the American Institute of Architects has partnered with the Classic Harbor Line to offer daily architectural sightseeing tours around — and beyond — Manhattan. Passengers can select from six different trips, including an industrial waterway tour of Freshkills Park and a nighttime viewing of the lights of the city.

Times vary. Most tours leave from Chelsea Piers (Pier 62 at Hudson River Park); 2019.archtober.org (or: aiany.org/architecture/tours/boat-tours/)
