The RhB also connects the Upper Engadine with the Lower Engadine as far as Scuol, and connects the Lower Engadine since 1999 via the Vereina Tunnel to Klosters and the Prätigau; another connection to the rest of Switzerland. In the summer, the Albula Pass is also open for car travel. The Julier Pass, north above St. Moritz, connects the Engadine with the rest of Graubünden for the whole year. Regular Swiss PostBus lines connects the Upper Engadine with the Val Bregaglia, Chiavenna in Italy, and even further to Lugano in Switzerland again in the west.
