French River Provincial Park

Your first real stop out of Toronto. The French River was the first waterway in Canada designated a Heritage River — walk the 500-foot suspension bridge over the gorge before you're back on the highway.

Free to visit
02KM ~400

Sudbury

Northern Ontario's largest city, and a legitimate stop rather than a gas-and-go. Science North, Dynamic Earth and the Big Nickel anchor a day here, with Lake Laurentian Conservation Area for trails right in town.

Full day recommended
03KM ~450

Killarney Provincial Park

An hour past Sudbury and worth the detour. The "Crack" trail cuts across pink Canadian Shield granite to a panoramic lookout over the La Cloche Hills and Georgian Bay — one of the best day hikes in the province.

Moderate–hard hike
04KM ~700

Sault Ste. Marie

Your last proper city before the Lake Superior coastline gets remote. Refuel, stock up, and eat well — the drive north from here has long stretches between services.

Last major services
05KM ~800–1000

Wawa & the Lake Superior Coastline

This stretch is the reason people do this route. Dramatic cliffs, cold-water beaches, and pull-offs at nearly every bend — Pancake Bay and Batchawana Bay make good overnight anchors.

Scenic core of the trip
06KM ~1150

Ouimet Canyon Provincial Park

About an hour east of Thunder Bay. A short boardwalk leads to a canyon that plunges roughly 100 metres straight down — one of the most dramatic short stops on the entire route.

30–60 min stop
07KM ~1300

Thunder Bay & Sleeping Giant Provincial Park

Journey's end, and worth two or three nights. Walk the waterfront, visit the Terry Fox Monument, and drive the hour out to Sleeping Giant for cliff-top hikes over Lake Superior — a strong base for aurora viewing on a clear night.

2–3 nights
