MacKinnon Ravine is long and wide. It borders Crestwood on one side and the Grovenor and Glenora communities on the other. It starts in the west on 149 Street near Stony Plain Road and continues east to Government House Park.
Government House Park offers places to picnic, shady trees to sit under and restful views of the river. In winter, the hill below the Royal Alberta Museum is a popular place for tobogganing. Ramsey Ravine is a tributary to MacKinnon Ravine.
