The World’s Coolest Underground Attractions.
Montreal, Canada – While Australians build down to escape the heat, Canadians dig deep because of the cold. The recently rebranded RESO, better known as Underground City, is made up of 32 kilometres of mostly interconnected tunnels, used by up to 500,000 visitors and locals daily. Thanks to the sprawling network, you can get to work and back, shop, eat, visit a museum, concert hall, cinema, the library or even a hockey game, without ever stepping outside. While Toronto’s underground PATH is the longest continuous system of its kind, with 27 kilometres of uninterrupted tunnels, Montreal’s RESO, with several separate systems, adds up to the largest total area. montrealundergroundcity.com
