PATH - The Underground City

PATH is informally, and more friendly, called the Underground City. It is a set of interconnected walkways below street level. These walkways connect the major buildings of the financial centre to each other. It is a fantastic system to move from building to building in a comfortable temperature when it is either scorching hot or icy cold outside. A lot of the walkways are nothing but shopping centres in disguise and they have stores lining the path, with food courts sprinkled in.

Close to the starting point: The Eaton Centre. The real starting point is the Atrium on Bay, but since it not accessible from Yonge Street at this time, I think it better to consider the Eaton Centre as the de facto starting point.
