Sweden's inland waterways comprise two separate commercial routes serving the hinterlands of the ports of Stockholm and Gothenburg respectively, and a number of smaller canals. Mostly interconnected, these were built to serve the country's industrial and agricultural development, but since the last barges ceased operating in the 1950s (or earlier), these canals have all become important tourist assets, used by passenger vessels and private boats, as well as some hire boats, during the four-month season (mid-May to mid-September)…

"Six canals in six days" is the theme of the 10th World Canals Conference, was held in Sweden on August 21-27 2005.
