This may be 30 kilometres west of where the Saint Lawrence officially starts, but its feels like it should be the first ferry in my set. Unlike many it is not linking an island to the mainland. It is not a lifeline, but it is a very useful and picturesque way of going between Kingston and the pleasant lands of Prince Edward County.
My first use of this ferry goes back to the first time I visited Kingston in 1975 before I moved to Canada. I saw my first pileated woodpecker near the ferry on that occasion! Over the years since we made the very occasional crossings, but now we are living part-time in South Frontenac Picton and Prince Edward County are local to us and the ferry is by far the nicest way of getting there.
Highway 33, The Loyalist Parkway, starts in Kingston as Bath Road, and runs west, past the back garden of my wife's one-time home and at Collins Bay it reaches the shore of Lake Ontario which is follows all the way to the ferry dock at Adolphustown. It continues at the dock at Glenora, passes through Picton and then wends its way through the middle of Prince Edward County. The last time I visited the excellent National Air Force Museum of Canada at Trenton I returned via Prince Edward County and the Glenora ferry; I had the time and that was a far better experience than following trucks on Hwy 401.
If the weather is nice when you use the ferry take a small detour from Glenora to Lake on the Mountain. This is a lake and small provincial park on top of the hill immediately behind the ferry dock at Glenora, and gives an excellent view to the north. There are no park facilities here except for parking, a viewing platform and a toilet—
you're mainly here to look at the view out over the Bay of Quinte, and to watch the ferry cross. (From the ferry at Glenora head west along Hwy 33 for 700 m and then turn left onto County Road 7, and you will reach Lake on the Mountain after another 1.5
