Smokey Hollow Falls, also known as Grindstone Falls, Waterdown Falls or Great Falls is a beautiful ribbon waterfall in a leafy forest setting that flows from Grindstone Creek in Waterdown.

At 10 metres tall, this isn’t the area’s biggest waterfall, but this short and fast-flowing waterfall is surrounded by a great section of the Bruce Trail. It has a rugged footpath tracing its way up and down the ravine formed by Niagara Escarpment.

Once used to power a local sawmill, the falls are now the centre of beautifully rehabilitated park land.
