There is a campsite on an island right at Ivy Falls, as I recall.  There is a complete lack of privacy (few trees) so it might be best used as a lunchtime stop.  It's kind of pretty there.

Yes, if you kept moving everyday, I wouldn't think you'd have much trouble completing this route in 5 days.  The current heading up Bearpelt Creek can be formidable after big rains.  Its serpentine nature makes it particularly challenging for solo paddles... you just get up a head of steam & then you have to pry yourself off the bend, straighten out, & get going again.  If you are looking for solitude, this is a great route.  I doubt you'll see anyone once you've left Wolseley and then, again, until you reach Badwater (or, more likely, West Bay).  The portage into Badwater can be a bit tough to find.  The cliff campsite on Badwater offers a great view.  There's another such cliff campsite & view on the east side of West Bay on Quetico (though I prefer the nearby island campsite myself, just SE of the narrow strand of sand that separates West Bay from the main body of Quetico).

Walleye fishing along the Bearpelt Creek strand of lakes is pretty good, especially early in the season.  Also, some of the beaver dams along the way are quite remarkable structures.

I suspect Solotripper, Jim J, & a few others who frequently paddle this area can add quite a bit to my comments.
