Cambridge.

Cambridge sits on the Grand River where the Speed River joins it — a city formed in 1973 from the former mill towns of Galt, Preston, and Hespeler with the village of Blair, each retaining its own limestone heritage core. The Grand River is a Canadian Heritage River, and the Cambridge to Paris Rail Trail (about 19 km of stone-dust corridor on the Trans Canada Trail) follows the river south from the city to Brant County.

Inside city limits, the Mill Race Trail threads downtown Galt along the historic Mill Race, the Walter Bean Grand River Community Trail traces the river through Cambridge, Kitchener, and Waterloo, and Shade's Mills Conservation Area covers 365 hectares around its reservoir in the city's east end. Riverside Park in Preston anchors the Speed–Grand confluence, and Soper Park in Galt holds the Cambridge Sculpture Garden along the river.

Cambridge sits within the Haldimand Tract on the traditional territory of the Anishinaabe, Haudenosaunee, and Neutral Nations.
