Darnley Cascade, Waterfall in Crooks Hollow Conservation Area, Greensville, Hamilton, Ontario, Canada

Darnley Cascade is a small waterfall in Crooks Hollow Conservation Area in Ontario that drops about 4 meters over rocky terrain. The water is part of Spencer Creek and flows through a quiet, tree-lined setting surrounded by lush vegetation.

The cascade takes its name from the Darnley Grist Mill, completed in 1813 by Scottish settler James Crooks, who admired Lord Darnley and claimed him as an ancestor. The mill was sold to James Stutt after Crooks' death in 1860 and burned down in 1934; its ruins remain. In 1829 the mill complex was expanded to include a distillery, tannery, woollen mill and Upper Canada's first paper mill.

The waterfall takes its name from the Darnley Mill, which once used water as a power source for local industry. Visitors walking the trails can still see remnants of this past industrial use woven into the natural landscape.

The waterfall is easily accessible by car with parking available nearby and trails leading to the water. Wear comfortable hiking shoes since the paths cross uneven ground and you will be walking near rocks and stream beds.

Darnley Cascade is also called Stutt's Falls, a name used on vintage postcards after James Stutt bought the grist mill following James Crooks' death in 1860. The mill ruins beside the cascade are considered among Ontario's oldest ruins.
