Aaron Provincial park is 116.7 ha in area and support a rich ecological and cultural history. Ancient Aboriginal peoples used Thunder Lake as a historic food collection area and Thunder Creek as a canoe route. In the 1880's the Canadian Pacific Railway was constructed next to the present park site and was instrumental in opening the area to settlement in the 1900s. Over time, Thunder lake became an increasingly popular recreational site, and the need for a park here became apparent.

When a tract of homestead land reverted to the Crown in 1935, the site of the park was determined. The park originally developed as a work campsite park by the Department of Northern Development in 1935. It provided recreational use for travelers and great numbers of local residents.
