We used skis only the first two days - up to 11,000 ft. After that we switched to crampons. We picked up our skis on the way out and ended up putting them on the sled. Skiing with a pack, a sled, in mountaineering boots is fairly ridiculous. Not to mention it cost an extra 50 bucks to get the skiis on the plane. If I were to go back I would definitely bring plastic snowshoes.
