The railway line, which runs from Jelenia Góra (Hirschberg) in Poland through Szklarska Poręba (Schreiberhau) in Poland to Kořenov (formerly Grünthal or Polaun) in Czechia, is a branch line in Poland and the Czech Republic. Formerly known as the "Zackenbahn" (Zag Railway), the line through the Jizera Mountains was one of the first electrified railway lines in Germany and became known for the use of the so-called "Rübezahl railcars" of the DR Class ET89. Cross-border service, which had been discontinued shortly after the Second World War, was resumed in August 2010.

At 1,362 meters, the Szrenica (German: Reifträger) is a prominent peak in the western part of the Giant Mountains and is part of their main ridge. Since the border between Poland and the Czech Republic runs south of the main ridge at this point, the peak lies on Polish territory. Like the peaks of many other mountains in the Giant Mountains, the peak consists of the remains of ancient granite rocks that form impressive scree slopes. Interesting rock formations can be found on its slopes, including the Horse Headstones (Końskie Łby) and the Pig Stones (Trzy Świnki). The Szrenica is the local mountain of Szklarska Poręba (Schreiberhau) and the center of the Szrenica Ski Arena, the largest ski area in the Polish part of the Giant Mountains. A two-seater chairlift leads from the town to the summit in two stages. At the summit are the Schronisko na Szrenicy (Reifträgerbaude) and a meteorological observation station of the University of Wrocław. On the pristine Szrenicka (Hala Szrenicka) border meadow on the northwest slope of the Reifträger, at an altitude of 1,200 meters, stands the PTTK mountain hut "Schronisko na Hali Szrenickiej," which roughly translates as "Hostel on the Reifträger Meadow," the successor to the "Neue Schlesische Baude."

A wonderful - mainly gravel - ride through forests and beautiful views of the Karkonosze Mountains. On the way, the High Bridge at an altitude of 810m above sea level, waterfalls and cascades, mountains visible through trees and thousands of trees, that the soul comes alive.
