Marienklamm, Tragöß, Natural monument in Tragöß, Austria.

The Marienklamm is a roughly 100-metre-long gorge in the Haringgraben in Tragöß, Styria. The Haringbach, a tributary of the Laming, has cut through Holocene conglomerate rock (slope-debris breccia, Burgstall breccia). A footbridge runs through the gorge.

The gorge was carved over thousands of years by continuous erosion from the Haringbach stream cutting through the rock. This ancient geological process continues to shape this landscape formation today.

The name Marienklamm refers to Mary, but the sources record no pilgrimage or religious use of the gorge. What visitors notice today is the wooden footbridge that carries the path through the 100-metre passage, and in winter the frozen spray that once coated tree trunks felled here, making the site a practice ground for ice climbers.

A footbridge runs through the roughly 100-metre-long gorge, so sturdy shoes are needed on the wet, shaded planks. In winter the rocks and trees can ice over; the gorge was once used for ice climbing, so check conditions before entering.

The high humidity and limited sunlight create a special habitat where rare ferns and mosses grow on the rock walls. These plants are adapted to the damp environment and form a delicate ecosystem found only in protected gorges like this.
