For any interested in visiting Point Abbaye, the beginning point is L'Anse. When I was up there in October 2013 for the first and only time since 1982, there were some signs, but it'd be a good idea to ask for directions to confirm.
The road(s) from Skanee to Champion have not been traversed by yours truly since 1982. If anything, I'd imagine they're better, but things don't happen on the UP at the same pace expected elsewhere, so there again, I'd do some homework before cutting through there.
Enjoy!
