The staff at Three Sisters Backcountry are outstanding. Welcoming, helpful, and very quick replies to questions. We stayed at the Tam McArthur Rim Yurts. The yurts are clean and comfortable. All the facilities and equipment is in great shape; the knives were even sharp. The yurts provide quick access to great ski terrain, and the portering service means you can bring all the luxuries you want. And theres a sauna.
