Mountain Locks Park preserves traces of the old Welland Canal, giving St. Catharines a quieter way to tell its canal story than the modern Lock 3 viewing area. Stonework, green space, and interpretive context show how ships once climbed the Niagara Escarpment by a very different route.
It is best for travellers who like industrial archaeology and do not mind a modest site. Pair it with the Welland Canals Centre to see both the old engineering problem and the modern solution.
