A great way to spend the day out in winter is to go snowshoeing.
This classic 4-5 hour snowshoe hike with panoramic views as far as the Glarus Alps. The marked trail from Brambrüesch to Feldis leads over a gentle plateau with many vistas around the Dreibündenstein. The descent leads along idyllic landscapes with snow-covered forests and alp settlements to Feldis from where you can take the cablecar down.
The Chur tourist website provides more information for your pleasure to go out.
