Last time up that way I did Highway 60 through Algonquin Park. This time I'm going to stitch together another route that is as different as possible.
Algonquin does a colour report that I'll keep an eye on and see if we can time a couple of days up that way when the colours are peaking. Discover Muskoka does one too. Last year we went up to the Kawarthas for Thanksgiving (early October in Canada):
...and it was right before the colours changed. Only the somac was in full colour. I'll see if I can time it a bit better this time around at sync it up with a big last ride before the snows come.
Autumn on the Canadian Shield is a beautiful thing.
