About Barrage de l’aménagement hydroélectrique de Lavey (VD)

Its modest height of 11 m makes it approachable for visitors, while the surrounding valley offers sweeping vistas of verdant meadows, rugged rock faces, and the distant silhouette of the Swiss Alps.

What to Expect
Arriving at the Lavey weir, you’ll be greeted by a modest concrete structure spanning the river, its spillway gently guiding water toward the hydropower intake downstream. The site is deliberately low‑key—there are no ticket booths or large visitor centers—so you can enjoy an unfiltered encounter with both engineering and nature.
- Soundscape: The constant, soothing rush of water creates a natural soundtrack, punctuated occasionally by distant bird calls.
- Visuals: The 11‑metre‑high wall contrasts with the emerald‑green river, while the surrounding alpine meadows provide a vivid backdrop. On clear days, the peaks of the Bernese Alps peek through the clouds.
- Photography: Early morning light casts soft reflections on the water; late afternoon sun highlights the weir’s texture. A wide‑angle lens captures the full panorama, while a telephoto lens can isolate the water’s flow.
- Accessibility: A short, well‑maintained path leads from the parking area to a viewing platform. The terrain is mostly flat, making it suitable for families and casual walkers.
- Safety: The water can be swift near the spillway. Stay behind the railings and avoid stepping onto the concrete spillway itself.
