Beautiful wooden boardwalk opposite the climbing rock. A beautiful, varied hiking trail runs along the river, and a panoramic path leads back above it.

October 4, 2025, Elbe Source

Its symbolic source lies at an altitude of 1,386 m above sea level. It is enclosed in a brick ring with inflow and outflow, and its stone-paved surroundings offer benches for relaxation. In 1968, a wall of rough rock was added, bearing the coats of arms of 26 important cities through which the Elbe flows on its way to the North Sea.

The castle was founded between 1260 and 1280 by the Markwartings. This family, from which several Bohemian noble families emerged, rose to prominence during the reign of King Otakar II Přemysl and owned extensive estates in the Jizera region up to the Giant Mountains. The first documented owner was Zdeněk (1280–1304), who named himself after the castle of Waldstein. He was the son of Jaroslav of Turnov (1234–1269). In addition to the castle, the Waldstein domain included several villages on both sides of the Jizera River, around Turnov, up to the Cistercian monastery of Hradiště. Even during Zdeněk's lifetime, disputes over ownership arose, which continued in subsequent generations. From 1318 onward, court proceedings between members of the Waldstein family for robbery in the associated villages are documented.
