Why September Is Arosa's Best-Kept Secret
While summer is brimming with vibrant energy and winter transforms our peaks into a snow-covered paradise, there is a hidden, fleeting season in the Swiss Alps that true mountain lovers cherish more than anything else.
It's happening right now—in September.
Locals call this time of year the “Alpine Indian Summer.” It’s the season when the summer crowds have left, the air becomes wonderfully clear and fresh, and the landscape slowly takes on warm copper and gold hues. If you’ve 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 bustling with activity. In September, they transform into an oasis of tranquility. The hiking trails branching off from the Weisshornbahn are pleasantly peaceful. You hike for miles, accompanied by nothing but the gentle rustling of the wind in the pine trees and the occasional whistle of a marmot. It feels as if the entire microcosm of Graubünden belongs to you all by yourself.
The razor-sharp visual magic
There’s a scientific reason why photographers love fall in the Alps so much: 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 that look almost like they’re dusted with icing. Further down in the valley, the larch trees are just beginning to turn a brilliant golden yellow and are beautifully reflected on the mirror-smooth surface of the Obersee.
Refreshing Alpine mornings, relaxing 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 cup of coffee on your suite’s private balcony as the fog rises over the lake. After a day full of discoveries in the crisp outdoors, there’s no greater luxury than returning to the “ Postresidenz ” to warm up. Spend your afternoon in the cozy warmth of our Finnish sauna, steam room, and hot tub.
Hearty, Seasonal Comfort Food
As soon as the evening temperatures drop, our culinary focus shifts as well. When you step into the Luftpost restaurantin September, you’ll be greeted by comforting, seasonal aromas. It’s the perfect time of year to transition to richer, heartier dishes and exceptional local harvests that pair beautifully with a full-bodied red wine from our global wine cellar.
Make the most of the last few days of the Arosa Card
One of the best practical benefits of a short trip in September is the chance to enjoy all the premium perks of the Arosa Card without having to deal with the long lines of peak summer. Take advantage of free rides on the regional mountain railways, free admission to local attractions, and hassle-free mountain transportation until our last day of operation.
Your golden fall vacation awaits you
September in Arosa reminds us to slow down, take a deep breath, and consciously savor the changing of the seasons. But just like the golden leaves on the trees, this window of time is incredibly short.
Treat yourself to the experience of one last autumnal mountain sunset, a peaceful boat ride on the lake, and the unparalleled comfort of our waterfront suites before we close our doors on September 27 to prepare for the magic of winter.
