The Rear Range Lighthouse at Port Dalhousie is a compact reminder that St. Catharines grew around water routes as much as roads. Range lights helped vessels line up safely with harbour and canal approaches, a practical maritime system now easy to overlook.
Visit it while walking the Port Dalhousie waterfront or Lakeside Park. It is not a major lighthouse museum, but it gives a tangible point of connection to Lake Ontario navigation and the Welland Canal story.
