Although, as we have before said, almost every valley of the Hohen Tauern range is notably beautiful, none excel in interest either pictorially or geologically the longest and widest, the Gastein Valley, with the fine falls some 500 feet in height near Bockstein, where the Gasteiner Ache, after passing through narrow gorges, plunges down into the valley, and thence flows through the broad, flat plain of Hof-Gastein to join the Salzach, passing on its way delightful Bad-Gastein, with its old town of interesting and picturesque wooden houses nestling on the eastern slopes of the valley, and the newer, with its hotels, churches, villas and other handsome buildings, peeping out from amid the pine-clad slopes or lying in the valley itself. It is a delightful though nowadays fashionable health resort, at which many tastes, both gay and quiet, are consulted. From Lend at the foot of the Gastein Thal to pretty little St. Johann, where the Salzach flows northward, the river has passed without opposition quietly onward. But at St. Johann are some towering and remarkable limestone peaks, including those of the Tennen and Hagen Ranges, some of them attaining an altitude of 8000 feet; with the desolate-looking Steinerne Meer, 8800 feet on the western flank, and the Dachstein more than a thousand feet higher on the eastern. The river flows onward to a point where the two ranges we have mentioned coalesce. Here the great ravine known as the Lueg Pass, six miles in length and possessing fine scenery, forms a very fitting entrance to the beautiful valley of Golling, which gradually opens out from Hallein onwards till Salzburg itself is reached. The valley of the Salzach on its eastern side is bordered by a range of pleasant green-clad heights and gentle slopes, with the Gaisberg, 4290 feet, a short distance to the north-east of Salzburg itself, dominating them, from which point the mountains gradually decrease in height. From Golling onwards, however, the western side of the valley is shut in by great peaks, some of which spread out their lower and rounded emerald green slopes towards the river. Of these impressive and beautiful mountains the Hohe Göll, 8275 feet, the majestic Watzmann, 9050 feet, the chief of the Berchtesgaden group, are the most noticeable. The cave-pierced and lofty, dome-shaped Untersberg, the highest point of which is the Berchtesgadener Hochtron of 6480 feet, standing isolated like a sentinel in the plain near the city.
