Established in 2007, the Marion Dunn Heritage Trail, located in Chaffeys Lock, provides a pleasant, easy walk through towering trees, including many large cedar trees. It guides hikers down an old road and past the area’s old lime kiln and blacksmith’s shop all the way to the Chaffey’s Lock Cemetery. Here are cut rocks Colonel By decided were not worthy for use by the canal builders, but have become a memorial wall for residents and visitors. The cemetery has 72 graves of canal workers that came from many different lands. Although no longer maintained by Parks Canada, the Marion Dunn Trail is open to the public to use at their own risk.
