Go to Lake Superior Provincial Park. Your best chance of seeing sandhill cranes is along 17 between Espanola and the Sault. I have seen them twice there - once in th ditch beside 17 and most recently at Hwy 6 and Lang Lake Rd (Hwy 6 is the road that comes up to intersect with 17 from the ferry to Manitoulin.)
The best place to eat once you get north of th Sault is Batchewana Bay - the Voyageur (look it up on tripadvisor) has great breakfasts andd is also a motel. Across the road from it is Batchewana Bay Provincial Park, a day use park with a stunning long beach. We have seen mergansers and mink there. It is also where the Superior water is warmest.
Just outside Batchewana is Salzburger Hof, which has a great fish fry each summer Friday. See its website. North of Batchewana, there is not much civilization. Just big honkin' group of 7-type sweeping vistas of lake and rock and sky and trees. You can camp at Pancake Bay Provincial Park, which has another beautiful beach but isn't too wild as it parallels the highway. It has electrical
hookups, showers, etc. - try to go towards the north end as you get less highway noise.
If you want seclusion, go up to the Crescent Lake campground in Lake Superior PP, or Rabbit Blanket Lake. Beware of the giant grade at Montreal River Harbour (which is about the only place to get gas between Batchewana and Wawa.) At Rabbit blanket Lake we have fished and had loons swim up to check us out.
I might even reveal where Secret Beach is.....
