The gorge is entirely carved through crystalline rocks, specifically gneiss, typical of the Aiguilles Rouges range.
The site was pioneered for tourism by a local blacksmith named 'Ancey' in the late 19th century.
The Diosaz river acts as a natural boundary separating the Aiguilles Rouges nature reserve from the lower valley slopes.
The trail construction involves a system of wooden and iron walkways bolted directly into vertical cliff faces.
The water flow is subject to high seasonal variation, often peaking during the snowmelt period in late spring.
Gorges de la Diosaz is a natural canyon located in Les Houches, carved by the Diosaz torrent as it descends from the Aiguilles Rouges massif. The site features a series of narrow, reinforced pathways and bridges suspended directly above the water, allowing visitors to traverse the depth of the gorge. It showcases five distinct waterfalls throughout the trail. The path is built into the rock face, providing intimate views of the geological stratification and erosive patterns of the canyon. The entire route is approximately 1.3 kilometers long. It has been accessible to the public since its opening in 1875. The site remains a rare example of 19th-century alpine tourism infrastructure that is still maintained for visitor access.

Wear footwear with high-traction rubber soles, as the metal grates and stone paths remain consistently damp.
Bring a light waterproof jacket regardless of external temperature, as the proximity to the falls creates significant spray.
Visit during the early morning hours to avoid the peak crowds that arrive from the Chamonix valley.
Attempting the walk in flip-flops or open-toed sandals, which are hazardous on the wet metal grating.
Open seasonally from mid-spring through early autumn; closed during winter months due to ice and snow hazards.
Stay within the marked safety barriers; children must be supervised due to narrow walkways and steep drops.
