Barker's Bush is a forest located in the Grand River watershed near the banks of the Nith River in the community of Paris, County of Brant, Ontario, Canada. The bush is directly north and west of Lion's Park, and less than one kilometre northwest of the confluence of the Nith and the Grand rivers.
Consisting of a mix of both coniferous and deciduous trees common to the Carolinian forests of southwestern Ontario, the bush itself is riddled with extensive bike and hiking trails which are used frequently, especially so through the warmer months (typically late Spring through early Fall). The vast majority of Barkers Bush historically has been located on private property, however, trespassing has generally been accepted and the public has used the trails extensively for many years.
