The Cheltenham Badlands are in Caledon, Ontario, on the southeast side of Olde Base Line Road, between Creditview and Chinguacousy Roads. The site occupies an area of approximately 0.4 square kilometers and features exposed and highly eroded Queenston shale. The Cheltenham Badlands are a significant educational site due to the readily visible geologic processes and the red colour and the unique topography of the exposed shale make this a popular tourist site. The site is a Provincial Earth Sciences Area of Natural and Scientific Interest (ANSI) since it is considered one of the best examples of "badlands topography" in Ontario.

Caledon is a town in the Regional Municipality of Peel in the Greater Toronto Area of Ontario, Canada. The name comes from a shortened form of Caledonia, the Roman name for what is now Scotland. Caledon is primarily rural with a number of hamlets and small villages, but also contains the larger community of Bolton in its southeastern quadrant, adjacent to York Region. Some spillover urbanization also occurs in the south bordering the City of Brampton.
