The deep red color of the Badlands is caused by high concentrations of iron oxide, or rust, within the shale.
The formation dates back to the Ordovician period, approximately 450 million years ago.
Improper agricultural techniques in the early 1900s, specifically over-farming and soil removal, triggered the accelerated erosion that formed these gullies.
The Ontario Heritage Trust acquired the site in 2002 to protect it from increasing recreational damage.
Geologically, the feature is a rare window into the Queenston Formation that underlies much of the Niagara Escarpment.
The Cheltenham Badlands feature exposed Queenston Shale, a soft, red sedimentary rock formation eroded into undulating hillocks and gullies. Located in Caledon, Ontario, the site is managed by the Ontario Heritage Trust. The landscape was created by poor farming practices in the early 20th century, which stripped the soil and exposed the underlying soft shale to water erosion. The site underwent a major restoration project completed in 2018 to stabilize the land and mitigate human impact. Public access is strictly confined to a designated boardwalk to prevent further geological degradation. It is a rare geological site in Southern Ontario, characterized by its high iron oxide content which provides the deep red coloration.
From the elevated lookout point on the boardwalk, which provides a panoramic view of the entire eroded landscape.
Parking reservations are often mandatory; check the official portal before driving to the site.
Stay strictly on the elevated wooden boardwalk as the exposed shale is fragile and easily damaged.
Bring sun protection as the site is completely exposed with no natural tree cover.
Attempting to climb or hike off the designated boardwalk, which is strictly prohibited and monitored.
Closed during the winter months due to safety and ground conditions; parking reservations required during peak season.
No walking on the rock surface; pets must remain on leashes; strictly carry-in, carry-out waste policy.
