Lenzerheide/Lai - known as Lai in the Rhaeto-Romanic (rätoromanisch) - is a place in the Swiss Canton of the Grisons situated at a height of around 1450-1600m above sea level. The village forms part part of the municipality of Vaz/Obervaz, its governing body. Despite the village having a name of German origin, the Lenzerheide region itself falls within Romansh-speaking territory. The "Lenzerheide" or "Lenzerheidepass" often serves as the nickname for the section of the A-road (Hauptstrasse 3) that leads from Chur to Tiefencastel.
