Cheltenham Badlands in Caledon is the perfect day trip from the Golden Horseshoe to see a provincially significant Earth Science Area of Natural and Scientific Interest (ANSI).
The Cheltenham Badlands were formed over 400 million years ago by erosion and deposition, and their unique red colour is a result of the oxidation of iron.
The area was once fertile farmland, as settlers grew various crops, but farming practices caused erosion of the shallow topsoil, exposing the underlying Queenston shale. The changing seasons further accelerated shale erosion, resulting in this unique landscape. The gray streaks on the badlands are caused by chemical reactions with acidic groundwater that streamed over the shale.

Earlier, this distinctive landscape was open fully, allowing visitors to walk over the formation. This resulted in accelerated erosion of the sensitive red shale surface and caused permanent changes to the Badlands’ unique appearance.
To protect the Badlands from further erosion, the Ontario Heritage Trust and its partners at Credit Valley Conservation (CVC) and the Bruce Trail Conservancy closed the site in 2015 and developed a boardwalk that closed off physical access to the Badlands.
The site reopened in 2018 and is now managed by the Ontario Heritage Trust.

Taking pictures of this Mars-like geological feature isn’t the only activity you can do at the Cheltenham Badlands. You can also walk the accessible boardwalk section. Remember, there is no physical access to the badlands (i.e., you can not walk on them).
The 60 m boardwalk and viewing platform connect to 0.32 km Cheltenham Badlands Trail. If you want to hike more, walk the 1.33 km section of the Bruce Trail that traverses through the forest.
The region boasts stunning Fall colours, and the brick red coloured badlands, backdropped by golden autumn hues, provide a fabulous experience.
