Muskoka Steamships and Discovery Centre is the clearest expression of Gravenhurst's old lake-resort identity. The cruises leave from the wharf, and the centre tells the story of the steamships, wooden boats, and grand summer hotels that once stitched the Muskoka lakes together.
The star is RMS Segwun, launched in 1887 and still operating as a steam-powered Royal Mail Ship. Even if you skip a cruise, the museum side is worth time for anyone interested in how cottage country worked before the roads took over.
