What: Scenic mountain resort spa with an expansive hammam area, including a warm "crystal" pool with underwater jets to massage, and a hotter "emotional" pool with sea salts that leads to the outdoor whirlpool, white-marble steam bath, alpine sauna, experience shower, frigidarium, gym, and treatment rooms.
The look: Contemporary cool, with pine-wood treatment rooms and raw marble in the hammam area. The "crystal" pool and a Kneipp bath are under a glass pyramid (think Louvre) with views of the mountains and stars.
Who goes: Après-skiers in winter, après-trekkers in summer, and family members who do neither.
The treatment: The Green Forest includes a massage with fragrant mountain pine essential oil and will leave you ready to tackle the slopes.
P.S.: Want to skip the treatment? A $28 spa entry fee gives hotel guests access to the hammam and gym.
