WOW! All sorts of ideas going off in my head regarding West to East. Allow me to share:
ITINERARY # 1:
Night 1: Washington Creek. (Grab a shelter or campsite ASAP then spend day #1 doing a day hike of Huginnin Cove loop)
Night 2: Feldtmann Lake (With Sunset at Rainbow Cove)
Night 3: Siskiwit Bay
Night 4: South Desor
Night 5: Hatchet Lake
Night 6: McCargoe Cove
Night 7: McCargoe Cove
Night 8: Moskey Basin or Daisy Farm?
Night 9: Rock Harbor
ITINERARY # 2:
Night 1: Feldtmann Lake (With Sunset at Rainbow Cove)
Night 2: Siskiwit Bay
Night 3: South Desor
Night 4: Hatchet Lake
Night 5: McCargoe Cove
Night 6: McCargoe Cove
Night 7: Moskey Basin or Lake Ritchey or Daisy Farm or Three Mile
Night 9: Rock Harbor
In either itinerary--spending only ONE Day at McCargoe Cove--opens up the possibility of spending an extra night at one of the other camp sites--OR spending just one day at McCargoe on itinerary # 2--would permit you to stay at any two of the following four (Lake Ritchie, Moskey Basin, Daisy Farm, Three Mile).
All great options!
