Finland and Finns owe everything to water. Finland was populated along waterways and in the old days, waterways provided passage, food and culture. And livelihood: the foundation of Finnish welfare, green gold, has also been transported by water. In the fifth episode of Worlds of Water Petteri and Antti travel Finnish waterways to see what they look like today. The historical Rautalammi waterway in South Konnevesi has been revived since a national park was founded. Visitors to the national park want to go on water and have created a need for boat services. Petteri and Antti explore waterways on a cruise boat, a church boat and a steamboat. They travel by muscle power, rowing, and in winter by skiing or on snowshoes.
