Vorderkaserklamm

Vorderkaserklamm is a narrow gorge system in Sankt Martin bei Lofer through which the Oedenbach stream flows for about 400 meters. At certain points, the rock walls narrow to less than a meter, while depths reach 80 meters at other sections.

The gorge formed about 14,000 years ago when melting glacial water carved through the rock after the last Ice Age ended. It opened to the public in 1882, when wooden walkways and steps were first installed to allow passage through the narrow canyon.

The name references a former barracks nearby, and today wooden walkways and stairs shape how visitors move through and experience the narrow passages of this gorge.

Access is possible from May through October, with extended hours during July and August. Sturdy shoes with good grip are recommended, as the walkways can be wet and slippery from water spray and moisture.

A Stone Age experience trail leads to the gorge and displays full-size animal replicas, including a life-sized mammoth figure. This pathway blends geology with prehistoric history in an engaging way for visitors.
