Nestled between the towering peaks of the Mount‑Blanc region and the quiet villages of the valley, the Gorges de la Diosaz offer a slice of alpine magic that feels both wild and meticulously cared for. A gentle roar of water guides you through narrow stone corridors, while a series of wooden walkways swing above turquoise pools, letting you peer down at cascading waterfalls and the sheer rock faces that have been carved by glaciers over millennia. The experience is as much about the view as it is about the rhythm of the hike: a moderate trail that feels like a conversation with the landscape, perfect for families, seasoned trekkers, and anyone looking for a sustainable way to enjoy a beautiful gorge.
From the moment you step onto the first footbridge, the air changes – it smells of fresh pine and the faint mineral tang of river water. The path is dotted with informative panels that explain the geology, the flora, and the local effort to keep the site eco‑friendly, from waste sorting stations to the use of biodegradable chain oil on the suspension cables. Whether you’re aiming for a quick round‑trip walk or a longer exploration that loops through the nearby hamlet of Servoz, the Diosaz gorges promise a memorable day in one of the most beautiful gorges of the Alps.

The spectacular location of Gorges de la Diosaz
Located just a few kilometres north‑east of Les Houches and a short drive from the bustling centre of Chamonix, the Gorges de la Diosaz sit at the heart of the mount‑blanc region. The gorge follows the course of the river Diosaz, which has cut a deep, winding scar through limestone and schist, creating a series of natural chambers and ledges. The site is officially recognised as a natural site of high ecological value, hosting a variety of Alpine flora such as edelweiss, alpine saxifrage and dwarf pine.
Getting there is straightforward: from the A40 motorway, follow signs to Servoz and then take the local road toward the “Gorge de la Diosaz” signpost. Parking is available at the trailhead, and a clear map displayed on a stone plaque marks the main points of interest, including the locations of the wooden footbridges, the viewing platforms and the eco‑friendly waste sorting bins.
| What | Where | Approx. distance |
|---|---|---|
| Trailhead parking | Servoz‑Diosaz road | 5 km from Les Houches |
| Visitor centre | Near the first footbridge | 200 m walk from car park |
| Rest area | After the second waterfall | 800 m from start |
Suspended footbridges: walking the Diosaz gorges suspended path
The hallmark of the Gorges de la Diosaz is its suspended path – a series of sturdy yet elegant wooden footbridges that cling to the rock faces, giving hikers the sensation of walking on air. The path includes three main spans, each one carefully anchored with stainless steel cables treated with biodegradable chain oil to minimise environmental impact. The bridges vary in length from 12 m to 30 m and are wide enough for two people to pass comfortably, but narrow enough to keep the experience intimate.
These footbridges are not just functional; they’re also a visual celebration of the area’s commitment to sustainable tourism. The wooden planks are sourced from locally managed forests, and the design allows water to drain naturally, preserving the river’s flow around the structure. For those wary of heights, the first bridge is lower and follows the riverbank, while the second and third bridges ascend gradually, offering spectacular views of the surrounding cliffs and the misty waterfalls that tumble down into the gorge.
“Standing on the highest bridge, you feel the mountain breathing beneath you – it’s a reminder that we’re guests in a living museum.” – A frequent visitor
Practical details: opening hours, dates and fees
Because the gorge can become slippery after heavy rain or during the melt‑off period in late spring, the management sets clear opening hours and opening dates each year. For 2025, the official schedule is:
- Opening forecast: Mid‑May to early October, depending on snow melt and river levels.
- Opening hours: 09:00 – 18:00 daily, with a one‑hour closure at 13:00 for maintenance on the suspended path.
- Entry fee: €4 for adults, €2 for children aged 6‑12, free for under‑6s.
- Ticket purchase: Available on‑site or online via the official Chamonix Vibes portal.
During the peak summer months, the gorges can attract up to 300 visitors per day, so it’s wise to arrive early, especially on weekends. The parking lot fills quickly, but a waste sorting station is positioned at the exit to encourage visitors to separate recyclables, compostables and residual waste.
How to experience the trail: moderate hike, round‑trip options and family‑friendly tips
Choosing the right difficulty
The route through the Diosaz gorges is classified as a moderate hike and a moderate trail. It involves about 250 m of vertical gain over a distance of 3 km one‑way, making it accessible for most active families and casual walkers. The path is well‑maintained, with occasional steps of uneven stone and short sections of boardwalk. In general, the difficulty stems more from the desire to linger at each viewpoint than from steep ascents.
Round‑trip vs. out‑and‑back
Most visitors opt for the classic round‑trip that starts at the parking area, crosses the three footbridges, reaches the upper viewing platform, and then returns the same way. For those who prefer a linear experience, there’s an out‑and‑back variation that ends at the “Les Cascades” rest area, where a short shuttle service can take you back to the start.
- Round‑trip: 3 km, ~2 hours, ideal for photographers.
- Out‑and‑back: 2 km, ~1.5 hours, good for families with young children.
Family‑friendly considerations
The gorge is marketing itself as family friendly. Strollers can be used on the first bridge, though the second and third bridges are best tackled with children over eight years old. Remember to bring a small first‑aid kit, as the stone steps can be slippery after rain. Water bottles are essential – the river is cold and not suitable for drinking, but you’ll find a filtered water station near the final viewing platform.
Sustainable tourism: waste sorting, eco‑friendly measures and biodegradable chain oil
One of the proudest achievements of the Gorges de la Diosaz management is the seamless integration of eco‑friendly practices into the visitor experience. The site uses biodegradable chain oil on all suspension cables, ensuring that any runoff does not harm the aquatic ecosystem. Moreover, the waste sorting stations are clearly labelled and are part of a larger Alpine network that recycles nearly 80 % of the waste collected on the trail.
In addition to these measures, the wooden components of the footbridges are harvested from sustainably managed forests in the valley, and the construction process was overseen by local craftsmen to minimise carbon emissions. Signage throughout the gorge reminds hikers to stay on the marked path, to respect wildlife, and to avoid leaving any litter – a simple yet powerful message that has helped keep the gorge pristine.
Nearby attractions: Servoz, Les Houches and Lac de Passy
If you have a few extra hours after exploring the gorge, the surrounding area offers several attractions that complement the alpine experience. The charming village of Servoz lies just a short walk away and features a small museum dedicated to local mountain trades, from cheese making to traditional woodcraft. Les Houches is a larger resort town with a bustling market, ski lifts for winter sports, and a network of family‑friendly hiking trails that radiate from the town centre.
For a tranquil lakeside break, head to Lac de Passy, a crystal‑clear water body nestled at 1,950 m. The lake is a popular spot for picnics, paddle‑boarding and spotting the occasional marmot. A short, well‑marked trail connects the lake to the Gorges de la Diosaz, making it easy to combine both sites in a single day.
