Scenic Backroads of Southwestern Ontario

A scenic journey through the backroads of Southwestern Ontario, exploring coastal towns, provincial parks, and historic routes.

Chatham-Kent → Erieau → Rondeau → Petrolia → Bayfield → Grand Bend → Pinery → Sarnia

  1. Coastal Cliffs and Lakeside Charms

    Starting in Chatham, we’ll skip the 401 entirely and head south toward the shores of Lake Erie. This route is all about the "Talbot Trail" (Highway 3), which offers a much more soulful look at Ontario's farmland and lakeside bluffs than any expressway ever could.

    • Chatham-Kent

      grab a coffee and some snacks for the road before heading south. The goal is to hit the water as quickly as possible.

    • Erieau

      This is a hidden gem on a sandbar. Walk out onto the long pier to feel the lake breeze, then grab some perch or pickerel for lunch at a local spot near the marina. It feels more like the East Coast than the Midwest here.

    • Rondeau Provincial Park

      Driving through the old-growth Carolinian forest here is magical. It’s one of the best spots in Canada to see rare birds or just walk the sandy beaches without the crowds of Wasaga or Grand Bend.

  2. The Slow Road to the Shore

    Today we cut across the peninsula toward Lake Huron. We’ll be using Highway 21, often called the "Bluewater Highway," but we’ll take the inland county roads first to see the rolling hills and quiet hamlets that make south Ontario feel so peaceful.

    • Petrolia

      Known as "Canada's Victorian Oil Town," the architecture here is surprisingly grand. Drive past the Victoria Playhouse and take a quick peek at the old wooden oil derricks that are still pumping in the fields nearby.

    • Bayfield

      This is arguably the prettiest town on Lake Huron. The main street is lined with massive trees, boutiques, and cafes. It’s a bit of a detour north, but the historic vibe and the view from Pioneer Park down to the lake are worth every extra kilometer.

    • Grand Bend

      Since we're avoiding the highways, the drive south along the coast from Bayfield to Grand Bend is stunning. It’s a classic beach town—walk the main strip and find a spot on the sand to watch the famous Lake Huron sunset.

  3. The Blue Coast Finale

    Our final leg hugs the coastline of Lake Huron all the way down to the mouth of the St. Clair River. It’s a short drive, so we can afford to linger at the parks along the way.

    • Pinery Provincial Park

      This is the star of the show. The rare oak savanna ecosystem and the massive sand dunes are incredible. I'd recommend renting a kayak for an hour on the Old Ausable Channel—it’s super calm and great for spotting turtles.

    • Canatara Park

      As we pull into Sarnia, this park offers a massive beach and a "mini-farm" that’s fun for a quick nostalgic walk. It’s the transition point from the wild lake to the industrial heart of the city.

    • Blue Water Bridge

      We’ll end the trip under the massive arches of the twin bridges. Grab some "bridge fries" from one of the iconic food trucks—it’s a local rite of passage—and watch the massive freighters navigate the turquoise waters of the St. Clair River.
