From Chamonix to Zermatt, the skiers Haute Route (aka High Route or Mountaineers Route) glacier trek is a multi-day backcountry route along Alps with stays in catered huts. Along the way, you will be treated with huge glacial views, rugged peaks and beautiful valleys. It generally takes about a week of hut-to-hut skiing (along with some crampon hiking) to complete. The huts are managed by the Swiss Alpine Club. A guide is highly recommended.
Keep in mind that this route is not the same as the so-called Hikers Haute Route which is a lower level travers on hiking trails with lodging mainly in hotels instead of high altitude huts.
