Hi there,
One of the best things to do in Switzerland is admire the lovely and breathtaking nature views.
Switzerland is very popular with hiking and one particular trail I can recommend it's the trail from Schwaegalp to the summit of Mt. Saentis. This trail has lovely views along the way and it is very impressive. You will enjoy beautiful views around the Alpstein region and some popular hiking points in this region include Rotsteinpass, Messmer, Seealpsee, and Schaefler.
Another great place to visit is
Niederhorn in Bernese Oberland to appreciate panoramic views of lake Thun and lake Brienz from the cable cart.
