1000 Islands cruises of the magnificent St. Lawrence River and 1000 Islands. Gananoque Boat Line offers 1-hour, 2.5-hour and Boldt Castle Stopover cruises. 1000 Islands Cruises - Gananoque Boat Line is proud to feature our Canadian Tourism Commission and Ontario Tourism Signature Experience: 'The Lost Ships of the 1000 Islands'. Just off the historic town of Gananoque, half way between Toronto and Montreal, is a unique underwater archaeological site. Gananoque Boat Line offers passengers a cruise through postcard perfect island escapes, but the real story of the St. Lawrence is hidden under the waves. The boat line’s specially equipped vessels offer a spectacle few ever see without a wetsuit – the Lost Ships of the 1000 Islands. Using side sonar technology, researched interpretation, exclusive underwater video and historical photos, the 2.5-hour cruise highlights several wrecks, from the ice-ravaged Iroquois (sunk in 1763) to the Sir Robert Peel, an 1838 victim of pirate Bill Johnston. Once over a wreck, the vessel’s GPS system kicks in, illuminating large video screens. Passengers see exactly what lies beneath, from the delicate ribs of an 18th-century battleship to the masts of a scuttled schooner. Though it’s difficult to tear your attention away from the sumptuous mansions, the silent wrecks offer alternative evidence of an era of war, crime, terror and opulence. Ample parking, gift shop, restaurant, fully licensed vessels, accessible vessels, canteen on all vessels.
