Arosa - Viaduct Langwies
Easy hike through the forest to Litzirüti and on under the impressive Langwieserviadukt, where the Fondeierbach and Plessur rivers flow together.
The hike starts at the Untersee lake Arosa on the old Poststrasse. After the first hundred metres you may already enjoy a fantastic view on the reservoir lake, the Schiesshorn and the Furggahörner. The trail continues through the forest along the Plessur river all the way down to Langwies where a short cut leads on a narrow, romantic path under the 62m high viaduct of Langwies. The view from above can be admired from the train on the return journey.
