Driving along the highway from the airport just outside of Toronto towards Toronto you will see at least 3 signs telling you how far it is to Algonquin Park. Algonquin Park is at least a 3 hour drive from the airport if you remain close to the legal speed limit. No other Ontario attraction has that many signs along the highway from the airport telling you how far it is, even though Ontario Place, the CN Tower, the Royal Ontario Museum, the Art Gallery of Ontario and the Ontario Science Centre are all much closer (in the city of Toronto).
