The first time I did this route I saw and heard more wildlife than I'd ever experienced. It's a four day foray as deep into the park and as far away from the human-inhabited parts as you can get. So it makes sense that it would be thus. But the second time I did this route I saw nothing bigger than a chipmunk. Nonetheless I figured my burgeoning canoe-tripping pro daughter should experience this trip for its remoteness. If we saw big wild animals, it would be a bonus.
