i don't know if this will be any help to you or anyone else, but here's a list of the campsites and distances we traveled from West of Edmunton AB to Sault St Marie. For your ease this is the reverse of our actual route. Because we are self contained, we hardly ever now use campground washrooms, so we can't comment on those facilities. Our comments were valid at the time of visiting in July 2022.
Sault St Marie ON: Glenview cottages and campground. Friendly hosts, clean easy site for our 34ft. fifth wheel. Would stay again.
Hattie Cove campground ON: Distance 245 miles. A little tight backing into our site, but nice campground.
If you are aware of the book Winnie the Pooh, do not miss stopping off in White river to see where the true story all began. (Also worth watching the film "A bear named Winnie")
Thunder Bay ON. Distance 205 miles. Chippewa park. OK campground. We visited Kakabeka falls, Fox viewpoint, both worth seeing.
Wabigoon ON. Distance 215 miles. Wabigoon Lake campground. Very friendly host, convenient to highway. Would stay again.
Clearwater Bay ON. Distance 143 miles. Pye's landing and RV park. friendly host and large pull through sites. Would stay again.
Macgregor Manitoba. Distance 143 miles. Macgregor Lions club Campground. Loved this site, very peaceful and fees going to good causes. Would definitely recommend.
Grenfell Saskatchewan. Distance 201 miles. Grenfell recreational park and campground. A place to stop if you must but the campground was muddy and tight to negotiate. Would not recommend.
Battleford Saskatchewan. Distance 331 miles. Eileen Kramer campground. Decent campground but we were inundated with mosquitoes the night we stayed.
Alberta Beach AB. Distance 285 miles. Alberta Beach golf club. Decent campground with a bar. If it's still open we thoroughly recommend dining at "Mama's in the kitchen" Don't be fooled by the appearance of the place, it's busy for a reason, excellent food, large portions and as cheap as chips.
