The Envalira Tunnel (Catalan: Túnel d'Envalira) is a tunnel in Andorra that runs between Pas de la Casa near the Andorra-France border and Grau Roig (Ski resort). It enables its users to avoid the Envalira Pass. It is amongst the highest road tunnels in Europe.
Although situated within the borders of Andorra, the entrance at Pas de la Casa can be reached only via a bridge that is situated in France. The Andorra/France border post is therefore situated 2Â km within France, northeast of the access bridge, on RN22. On the French side it is connected to RN22, and on the Andorran side to the CGII.
