Set on the Saint Lawrence River where the dome of the Montreal Biosphere forms an arresting backdrop, the Parc Jean-Drapeau is a wonderful hub of culture and entertainment. This urban recreational park straddles two islands – the Saint Helen's Island and the man-made Notre Dame Island - which were bases for the Expo 67 World's Fair. Come summer, the park comes alive with a flurry of activities brought about by the major attractions that dot its vast, picturesque stretch, from La Ronde and Montreal Casino, to Fort de l'Île Sainte-Hélène and the Circuit Gilles Villeneuve. Its summery sprawl also invites droves of tourists who congregate here for the vibrant streak of festivals that are held year-long.
