One of the sounds that is ubiquitous in Old Québec is that of hooves on pavement.
Horse drawn carriages clop up and down the streets of the old city, giving tourists a privileged view at a civilized pace. They will take you around the Governors Park, by the Hotel de Ville, in front of the Parliament Building, through the Plaines of Abraham and back again. They work hard, these horses, asking only oats and water for pay.
Their masters, on the other hand, will ask for Canadian dollars – 90$, 170$, 250$ — depending on the length of your tour. Along the way, they will give you the history of the city through their eyes, loud enough to be heard over the din by customers and bystanders alike.
