As part of Parc Jean-Drapeau, the Circuit is open to visitors, between races, for walking, running, biking, in-line skating, etc. During the few days of the Grand Prix, Île Notre-Dame is one of the noisiest places in Montreal. At just about any other time of the year, it is one of the quietest, being located in the middle of a river, on an island filled with greenery and animals, joggers and cyclists.
