I'll give you a hint right off the bat; I know how frustrating
it can be to find yourself on the wrong side of the river, so here
you go: North side.
You don't need to put yourself in danger, but this may involve
rock ledges and the possibility of a perilous drop to a watery
demise, so for goodness sakes, be careful.
Also there is a small fence with a path around it where kids go
to jump into the river. You can go around this fence, but not the
bigger one with the "no trespassing" signs on it. In other words,
use common sense.
