Unlike the other four Great Lakes, Lake Ontario is posted not as a circle tour but as part of the US-only Seaway Trail. The trail begins in Erie County, Pennsylvania and travels through Buffalo, Niagara Falls, Rochester, Oswego, and Ogdensburg before ending at the Seaway International Bridge near Massena.
