The trail was pioneered by Henri Kastler, a local engineer and member of the Club Vosgien.
It is frequently referred to as one of the most technical and challenging hiking paths in the Vosges range.
The route segment between the Col de la Schlucht and the Frankenthal provides views into the heart of the glacial cirque of the Hohneck.
Hikers on the path must frequently navigate narrow passages where the mountain wall directly abuts the trail edge.
Portions of the trail are maintained using iron cables and pinned metal ladders for safety in steep sections.
The path serves as a critical link for accessing the various rocky buttresses used for historical climbing in the region.
It is situated within the Parc naturel régional des Ballons des Vosges.
The Sentier des Roches is a high-altitude cliffside path in the Vosges Mountains of France connecting the Col de la Schlucht to the Frankenthal cirque. The route traverses steep, exposed rock faces using metal handrails, steps, and bridges anchored directly into the cliffside. It represents one of the oldest marked trails in the Vosges, established by the Club Vosgien in 1893. The path features significant elevation changes and traverses rugged, uneven terrain along the side of the mountain. Hikers navigate past dramatic geological formations, including overhangs and vertical drops. The trail passes through protected forest areas and alpine meadows typical of the Grand Est region. It is classified as a technical trail requiring sure-footedness and a high level of physical conditioning. The route is prone to rockfall and localized erosion due to its extreme exposure.

Wear stiff-soled hiking boots with high traction, as smooth rock surfaces become extremely slippery when damp.
Carry a headlamp or flashlight if attempting the route late in the day to navigate shadowed sections.
Avoid this path entirely during or immediately after rainfall due to high risks of slips and falling debris.
Attempting the path in sneakers or standard running shoes; visiting during foggy, wet, or icy conditions.
Closed or highly dangerous during winter months due to heavy snow, ice, and avalanche risk; trail markers are often removed or become invisible in winter.
Hikers must yield to uphill traffic; stay on the marked path to protect fragile alpine flora and avoid loose rock edges.
