The Breitachklamm near Oberstdorf is not only the deepest, but also one of the most spectacular and impressive gorges in Central Europe.
However, in geological terms the gorges is relatively young. It was formed in the course of the last 10,000 years following the Würm glaciation. It is roughly 2.5 km long and 150 m deep. High waterfalls alternate with natural pools.
The Breitach, one of three Iller headstreams, flows through the gorges that is one of the deepest ravines in the Alpine area and was pracitcally inaccessible until the beginning of the 20th century. In 1904 the 2.5 km long gorges was made accessible by passageways that were chiseled in the rocks. You can still walk through Breitachklamm on those very same passageways today to admire the roaring water masses.
In the past, the Breitachklamm was called Zwingschlucht. The name of the bridge, Zwingsbrücke, still refers to that name. According to an old legend, the Zwinggeister (ghosts) haunted the gorge and mistreated everybody who made fun of them. Walking through the rocks at midnight to challenge the ghosts was regarded as a test of courage.
The entrances to the gorge, that are located at the upper end of the Kleinwalsertal and at their lower end in Tiefenbach near Oberstdorf, are usually open to the public all year round. If you do not mind the extreme cold, which is caused by the lack of sunlight in the gorge, a visit to the Breitachklamm during winter is recommended: the freezing cold turns the water masses into ice and thus create spectacular and almost surreal icicles.
