Closure Notice: Access to the tunnel along the O&W Railroad Pedestrian Promenade and Bikeway is interrupted while the canalway undergoes a myriad of projects. It is unknown when this connection will be reestablished.
The O&W Railroad Pedestrian Promenade and Bikeway, a unique city trail, was built on portions of the former Ontario and Western Railway Line through the City of Oswego. The Ontario and Western Railway ran its last train in March of 1957. The trail passes through a short tunnel, which was used by the now defunct railroad.
The O&W Railroad Pedestrian Promenade and Bikeway offers no dedicated trail user parking.
Please see TrailLink Map for detailed directions.
Well maintained short walk in the city ending at Fort Ontario. Includes an historic rail bridge over the Oswego River with great views. Would be 5 stars except the tunnel mentioned in the description is closed with no evidence that it’s going to be reopened.
