Get off of the boat and pull it to the right and up to the wall. Use the boat to jump up to the higher ledge. Climb the vine against the far wall and jump over to the hanging rope when possible. At the top of the rope climb up to the ledge above and continue right.
Shortly after you start downhill, you will be able to see a pair of bear traps on the ground. Pull the nearest one back towards you and then jump over it and the second trap. Continue right.
You will see a body on a rope, drop down below the rope and pull the bear trap in the corner so it is directly below the body on the rope. Jump onto the rope with the body on it and quickly climb up (if you are too slow, you will also be caught in the trap), the body should be snapped up by the trap. Swing across to the higher ledge.
