The Seaway Trail meanders along Lake Shore Road through northern Irondequoit and the city-owned Durand–Eastman Park and Sweet Fern Drive to Culver Road. The trail takes Culver Road south, away from Lake Ontario, in order to go around Irondequoit Bay. At Empire Boulevard, the trail starts eastward again. NY 404 begins a short distance along Empire Boulevard, and the trail follows them east and north-northeast along the shore of the bay. The trail next follows Bay Road, staying close to the bay shore, north-northwest to its terminus at Lake Road, just a tenth of a mile (.15 km) from Lake Ontario.
