Star Mine Suspension Bridge
I've no Idea if you can go into the old mine at all (probably not), it was closed in the 70s. But lots of people are out crossing the bridge and hiking on the East side of the river.
The Take out is just after this bridge on river right.
However it may be easier taking out one River left just above the bridge where the two fishermen are in the picture
