The small Alpine hamlet of Vals in Switzerland is where this high-altitude stay has thermal baths built from 60,000 slabs of local quartzite; book a penthouse suite and a helicopter pick-up is included in the room rate. Every room looks out over the Swiss Alps; the coffee shop stocks serious design books. A grown-up overnighter for spa and design devotees.

The Ursern Valley at 1,444 metres is home to The Chedi Andermatt, which has quietly redefined what Alpine smartness means since 2013. Sleek timber-and-stone architecture; an exceptional spa; and food across several restaurants that takes the local larder seriously. The ski access is first-rate; the summer hiking is extraordinary. A very considered and thoroughly well-run address.
