The Central Experimental Farm is a 426-hectare working agricultural research station that has been surrounded by the city since the late 19th century — one of those truly unlikely urban spaces that you have to see to believe. Established in 1886 as one of five experimental farms created by the new Dominion of Canada to develop farming for the climate, it now operates as both a research facility and a public green space open to all.
The farm contains ornamental gardens, an arboretum, working fields and livestock barns — all within Ottawa city limits, with Parliament Hill visible in the distance. The Canada Agriculture and Food Museum occupies part of the site and gives an engaging look at Canadian farming history, with live animals and seasonal demonstrations. The four kilometres of tree-lined lanes through the arboretum make it one of the best places in the city for a long walk, especially in autumn colour. In winter the fields are used for cross-country skiing. Free admission to the farm grounds; the museum charges a small fee.
