Because of its location at the bottom of a wide valley, Arosa is very sunny and to a great extent sheltered from strong winds. As there is no transit traffic, the air is particularly pure which is why Arosa has been a famous Alpine health resort since 1877. Arosa is accessible by Rhaetian Railways from Chur or by car across over 365 serpentines and through several tunnels, past the smaller holiday resort of Langwies.

Arosa is among the Swiss holiday resorts which have been awarded the «Families Welcome» quality label. In summer and winter the «Arosa JUNIOR Club» does its very best to provide an exciting children's programme. A few hotels in Arosa have come together under the label «AlpenClub Mickey Mouse Family Hotels» and cater for the needs of families in particular.

The Arosa Card is a special, visitor-friendly feature of the resort: it entitles visitors staying one or more nights in a holiday apartment, on a camp site or at a hotel to free offers, such as rides on mountain transport facilities up the Hörnli and Weisshorn.

Summer

The hiking region boasts 200 kilometres of varied walking and hiking trails. The 15-kilometre-long ten-lake-hike, for example, takes you past one crystal clear lake after another. And walkers doing the several-day tour from Davos via Arosa to Lenzerheide can have their luggage transported from one stopover location to the next. For mountain bike riders there are 50 kilometres of trails. There is also a luggage transport service for riders embarking on several-day tours.

Winter

For skiers and snowboarders there are 70 kilometres of groomed pistes as well as a 30-kilometre freeride area and a half-pipe. 13 transport facilities take passengers to altitudes of up to 2653 metres above sea level. Some of the 60 kilometres of winter walking trails take you right into the snow sports region which means that winter walkers can take advantage of the cosy huts and meet up with their relatives and friends who are indulging in sports on the slopes. And there are attractive routes for snow-shoe trekkers and toboggan riders too. At the snow sports schools of the «Arosa Junior
 Club» children learn to ski and ride snowboards in a fun way while experiencing an imaginative holiday at the same time.
