This impressive landscape in Caledon was first formed at the base of an ancient sea over 400 million years ago and was exposed in the early 1900s. The site is a provincially significant Area of Natural and Scientific Interest and one of the most recognizable and visited natural heritage landmarks in southern Ontario.

The formation is mostly red in colour due to iron oxide deposits with some faint green streaks due to ground water percolation changing the red iron oxide into green iron oxide.

The Cheltenham Badlands is owned by the Ontario Heritage Trust. Caledon’s Cheltenham Badlands temporarily closed!


Cheltenham Badland is located on the south east side of Olde Base Line Road, between Creditview and Chinguacousy Roads, west of Highway 10 in Caledon, and features exposed and eroded Queenston Shale. The formation is located along the Niagara Escarpment.
