Mario Botta's glass sails light a four-storey spa carved into the Arosa mountainside, with a private train to the snow.
Mario Botta cut a five-thousand-square-metre spa into the mountainside at Arosa and lit four subterranean floors with nine triangular glass sails that look like leaves from the outside. On a bright day the light comes down through the whole building.
The Bergsauna runs at ninety degrees with an open fireplace and infusions two or three times a day. Six pools, including ten-by-fifteen metres indoors and nine-by-six-and-a-half outdoors, both at thirty-four, plus warm and cold Kneipp pools at thirty-four and fourteen.
A private funicular, the Tschuggen Express, takes you from the hotel to the piste. The spa turns adults-only from six in the evening, which is a small and civilised piece of scheduling.
