• Watching the ibices (this animal is on the flag of the Canton)

• Spring hiking or Spring hiking 2 (some of the hikes includes the visit of the ideas above, i.e. Rhine Gorge or Cauma Lakes à 4-Lake-Hike)

• Viaducts are quite special to Graubünden

• Castles

Take the Rhätische Bahn (small local train) up to Alp Grüm (it wall pass some viaducts on its way). The landscape is absolutely incredible: glaciers, mountains and lakes without even stepping out of the train!
