One of My favorite hiking trails is the one to the Lago di Saoseo
The beautiful Lago di Saoseo is a lake in the Val da Camp, a valley in the Poschiavo region of the Grisons, Switzerland. It is famous for its deep blue water. The lake is considered the most beautiful lake of Grisons. It is a very nice but also easy hiking trail to the lake. During summer you will meet a lot of Swiss cows up there. On the way there you will pass many fountains where you can fill up your water bottle with cold and super fresh mountain water.
Once at the lake you can enjoy the epic view of the lake and the surrounding area invites you to a picnic. The circular hike goes from Sfazù, on the Bernina pass road, to Rifugio Saoseo, to Lago di Saoseo and back again.
