Sudbury, Ontario, has long been known for its mining industry — the city is home to ten mines, as well as smelters and refineries – but in recent times, it has reinvented itself as a major tourism attraction. Dynamic Earth, the Greater Sudbury Heritage Museum, and the Inco Superstack are just a few of the city's attractions. Science North is one of Ontario's most popular science attractions. It's also built right into Ramsey Lake's rocky shore.
