The Graubünden path, in Romanic Via Son Giachen, leads pilgrims coming from the Val Müstair and from South Tyrol through the canton of Graubünden and finally also the canton of Uri to the "path Central Switzerland", which it meets at Seelisberg/Oberdorf above Lake Lucerne. The partly quite alpine hiking trail (up to Amsteg it is signposted as regional route 43, then 77) is, by nature, only passable in summer on some sections.
