As you approach a structure, you should be able to see two bear traps on the platform above. These are actually attached to ropes and they will swing down when you get close enough. Move forward slowly, and as the first trap releases move slightly to the left to avoid it, then jump quickly to the right to avoid the second trap.

Avoid the traps that swing beneath the structure (left) and then climb the rope on the left (right).

You can now use the rope to the left of the structure to climb up onto a platform. Jump across two platforms then drop back down to ground level, continue to the right.
