It's long and rough but picturesque. You can paddle and lift over several big beaver dams for about a third of the way, then you hit an impassable canyon and need to hit the portage which runs up above on the left (going downstream toward Robinson). You might be able to plop the canoe in 100 yards or so from Robinson and paddle/drift the rest of the way--pretty little stream with a white sand bottom.
Most maps do not show it but it is actually a very nice paddle in the back bays of McIntyre on the way to the portage and the portage itself is really cool. Not well used but has a nice feel to the area. Depending on water levels there can be a fair amount of dragging/pulling the canoes in the river.
Here's a shot of McIntyre Creek about 50 yards below the waterfall coming out of McIntyre Lake. After portaging around this stretch you can put in and cross a large pool, then over a beaver dam, another large pool, then more stream, then it's time to walk.
Watch the moss covered cracks between the large boulders on this portage. My partner stepped in one of these in 94 and fell. Catching himself with his hand he spraind his wrist and couldn't paddle for 2 days. It was almost a trip ending deal on the second day. Here are a couple more pictures. qp
Take your journey and never look back. Life is too short, not to enjoy the necessities of the north woods.
