Sometimes the track was 20 meters off the river bank and other times if you tripped, you might just end up taking a swim.  Later in the track, I would hike along the Seaforth and it's a moderate sized river and as one ascends higher up towards Centre Pass, it turns into a mere trickle.  Neither of these apply to the river at this point.  It's wide, deep, and flowing very fast.  Tripping into the river on this day would have been a one-way ticket to misery.  So as long as you stay out of  water, it's a pretty river to see.
