The Oldman River valley parks system is a continuous collection of eight urban parks in the Oldman River valley of Lethbridge, Alberta, 100 metres (330 ft) below the prairie level. The parks were created in the 1980s as part of the city's Urban Parks Project. Today they are a combined 16 square kilometres (6.2 sq mi) in size and comprise one of the largest urban park systems in North America, and the third largest in Canada.[1]
