Hey Nullzone! When you start out as the human, turn left towards the snowy mountain peaks. There is then a gap between two rock faces. Travel between those. You will know you are in the right place because there is a group of men cutting down trees once you travel through. You will also see two large statues of men holding out their hands towards you (much like the Argonath in the LoTR). The Ents are walking around that area. I hope that helps!
