While summer is full of vibrant energy and winter transforms our peaks into a snowy paradise, there is a hidden, fleeting season in the Swiss Alps that true mountain lovers cherish above all else.
It is happening right now – in September.
Locals call this time the "Alpine Indian Summer". It is the phase when the large summer crowds depart, the air becomes wonderfully crisp and fresh, and the landscape slowly transforms into warm shades of copper and gold. If you have always wanted to experience the Alps in their purest, most peaceful state, then September is Arosa’s best-kept secret.

The luxury of absolute tranquility on the hiking trails
In July and August, the mountains are a lively playground full of activity. In September, they transform into an oasis of calm. The hiking trails branching off from the Weisshorn cable car are blissfully peaceful. You can hike for miles, accompanied by nothing but the gentle rustle of the wind in the pines and the occasional whistle of a marmot. It feels as if the entire microcosm of Grisons belongs to you alone.

Razor-sharp visual magic
There is a scientific reason why photographers love autumn in the Alps: the cooler September air contains less moisture than the warm summer air, resulting in unparalleled atmospheric clarity. The view from the striking summit of the Weisshorn is sharper than ever, offering a flawless panorama of hundreds of peaks lightly dusted with snow. Further down in the valley, the larches are just beginning to turn a brilliant golden yellow, reflecting beautifully on the mirror-like surface of the Obersee.

Refreshing alpine mornings, cozy spa evenings
September offers the perfect sensory contrast. The mornings are cool and crisp – ideal for wrapping yourself in a light jacket and enjoying a hot coffee on your suite's private balcony as the mist rises over the lake. After a day of discovery in the fresh air, there is no greater luxury than returning to the Postresidenz to warm up. Spend your afternoon in the soothing heat of our Finnish sauna, steam bath, and whirlpool.

Hearty, seasonal comfort food
As soon as the evening temperatures drop, our culinary focus shifts as well. When you enter the Restaurant Luftpost in September, you are greeted by comforting, seasonal aromas. It is the perfect time of year for the transition to richer, heartier dishes and exceptional local harvests that pair perfectly with a bold red wine from our global wine cellar.

Making the most of the final days of the Arosa Card
One of the best practical advantages of a September getaway is the opportunity to enjoy all the premium benefits of the Arosa Card without the queues of high summer. Take advantage of free rides on the regional mountain railways, free admission to local attractions, and effortless mountain transport right up until our final day of operation.

Your golden autumn getaway awaits
September in Arosa is a reminder to slow down, take a deep breath, and truly savor the changing of the seasons. But just like the golden leaves on the trees, this window of time is fleeting.
Treat yourself to the experience of one last autumnal mountain sunset, a peaceful boat ride on the lake, and the unparalleled comfort of our suites right by the water, before we, on September 27th close our doors to prepare for the magic of winter.
