The Natural Bridge is a stunning geological formation located near Hirschegg in the Kleinwalsertal, accessible via the parking lot at the Ifenbahn valley station. The hike to the Natural Bridge passes by the so called Kessellöcher and continues along the Schwarzwasserbach stream.

Geologically, the Natural Bridge is a naturally formed rock arch that spans over the cascading waters of the Schwarzwasserbach waterfall. This impressive formation was created over thousands of years by continuous erosion and weathering, where softer rock layers were worn away beneath harder, more resistant rock, leaving this spectacular bridge suspended above the water. It’s a vivid example of the dynamic power of alpine waterways shaping the landscape.

The walk from the Ifenbahn parking lot to the Natural Bridge is about 3.5 km one way, taking approximately one hour. The trail is well marked and mostly follows the river, offering beautiful views of waterfalls, rock formations, and forest scenery. Passing the Kessellöcher — bowl-shaped potholes formed by swirling water erosion — adds to the geological interest of the hike.
