i am getting so mad at this part i cant figure out how to get to old hugh after climbing down the cliff someone please help im desperate!!!

If you've climbed all the way down and can't go any further turn to your right and walk around to the back of where you climbed down. There is a hidden walkthrough tunnel at the back that you cannot see. Walk through here and it will take you over to Old Hugh. Hope this was of help to you. I remember this was a tough spot for me too. Just keep in mind while playing the game that there are tricky hidden things like this.
