ALBULA PASS, the principal route from the north to the Upper Engadine in the Grisons. It was used in the 13th century and a carriage road (highest point, 7,595ft.) was made across it in 1865, but for a long time it was not as much used as the easier and more direct Julier pass (7, 504f t.) . The opening of the railway in however, vastly increased its importance. Starting from Coire the railway follows the Rhine to Reichenau (64m.), and then the Hinter Rhine to Thusis (1 olm.) . It then runs through the grand Schyn gorge (cut by the Albula torrent) to Tiefenkastell (74m.), where it leaves the Julier road on the right (south), and continues to follow the course of the Albula past Filisur and Ber gun (I2-1m.) to the mouth (5,879ft.) of the tunnel (34m. in length; highest point, 5,987ft.) which has been pierced below the pass. The railway descends through the Bevers glen to Bevers (2m.), in the Upper Engadine, about 5m. below St. Moritz, which is 56m. from Coire by this route.
