I am stuck in the part with all the platforms in the trees. I get to the point where the bridge is broke and there appears to be a cable slide above my head. But I am unable to reach it. There are a couple of crates to jup on but I still can not reach it. Please help

The place with the crashed plane at the end of the gorge? (it's hidden up in the trees)

Go right to the end after the huge batle between you and all these super soldiers (or whatever they are called... ferral dudes..) use your ferral vision on some of the trees near the plabe (i think its the one to the left if your facing it...)

You will have to jump up to reach the climbable part of it.... (its pretty hard to see too... how annoying this game can be at times!)
