Collector that you can't get to?

When you leave Amnoon, just before you get to the teleporter, there is a collector on the cliff above you. How do you get to him?

You have to go through the teleporter, hook a right, go through the minotaurs, and then continue to the right until you're in the valley.

Once you go through the valley, you'll see a small path to the left. You can access him through there (I think he has collector's boots).

You can also get to the valley from the north.
