Siweschlëff Travel Guide

Siweschlëff, sometimes referred to as the 'Seven Holes,' lies tucked away in the rocky heart of the Mullerthal—often called Luxembourg's Little Switzerland for its striking geological shapes and winding woodland trails.

This natural labyrinth, beloved by families, hikers, and keen explorers, offers a rare chance to wander through slots so slim that you can stretch your arms and touch time-worn stone on either side.As you delve deeper, a cool, earthy air surrounds you, accompanied by the soft crunch of forest debris underfoot and shafts of light sneaking in from above. The magic of Siweschlëff lies in its playful unpredictability—a new window or rocky chamber appears at every turn, inviting whispers, echoes, and laughter. Though the trails curve in many directions, there’s always a sense of discovery, whether you’re tracing ancient watercourses along the base of massive cliffs or letting curious young ones climb up mossy boulders under the watchful gaze of natural stone arches.The surrounding Mullerthal region supports a diverse suite of hiking routes, with Siweschlëff serving as a highlight along one of the most scenic stretches near Berdorf.
