Huemul Circuit

Part of Parque Nacional Los Glaciares, near el Chaltén. Glacier walks, massive views of the southern ice field, gnarly river crossings, swimming in an iceberg bay. Most technical hike ever done. Includes two Tyrolean traverses where you need to harness up and pull yourself across the cable - one over a deep gorge and the other over a wide river. Handful of other ropes sections as well.
