You'll love north of Superiour ride! Fill your tank every chance as there are big gaps between gas stations especially from Wawa to the Soo. Be sure to take in the Bush Plane Museum in the Soo. I live in the Muskoka 'cottage country' and you could spend a few days enjoying local rides here if you have a place to stay. Lots of accommodation in Huntsville. A ride from Huntsville through Algonquin Park, then south to Bancroft on the Haliburton up to Dorset and back to Hunstville is a fantastic day loop with lots of great scenery and places to eat (Firey Grill in Dorset, Mckecknies in Haliburton, Dockside or Cottage Grill in Huntsville) You'll love the twisting roads and low traffic on this route... even more on a SERG...I speak from experience!
Enjoy your trip!
