2. About Barrage de Monteynard

A Brief History

The Barrage de Monteynard (also known as Monteynard‑Avignonet) is a concrete gravity dam built to harness the hydro‑electric potential of the Drac river. While the exact construction date is not the focus of this guide, the dam has become an integral part of France’s renewable‑energy network, supplying clean power to the surrounding region. Its imposing 135 m height makes it one of the most striking dams in the French Alps, and the reservoir it creates—Lake Monteynard—covers an area that stretches over several kilometres, offering a pristine water surface that reflects the dramatic Alpine landscape.

Why It Matters

Beyond its functional role, the Monteynard dam is a symbol of the harmonious balance between engineering and nature. The structure’s sleek, modern lines sit seamlessly against the rugged mountains, while the reservoir has transformed the valley into a year‑round playground for water sports, hiking, and wildlife observation. The dam also serves as a gateway to the Parc naturel régional du Vercors, a protected area renowned for its limestone cliffs, deep gorges, and rich biodiversity.


3. How to Get There

By Car

  • From Grenoble: Take the A48 motorway toward Briançon, then exit onto the D1090 toward La Motte‑Saint‑Martin. The drive is about 45 km and takes roughly 1 hour, depending on traffic.
  • From Lyon: Follow the A43 to the A48, then continue as above. The total distance is around 150 km (≈ 2 hours).

Parking is available at the Monteynard Visitor Area near the dam’s main access road. Look for signs that read “Parking Barrage de Monteynard” – the lot fills quickly in summer, so aim to arrive early.

By Public Transport

  • Train: The nearest SNCF station is Grenoble. From there, catch a regional TER bus (line G) to La Motte‑Saint‑Martin.
  • Bus: Local bus routes (e.g., the RĂŠgion RhĂ´ne‑Alpes line 140) stop within a 5‑minute walk of the dam’s main entrance.

By Bike

The dam sits on the VéloVercors cycling network, a series of well‑marked routes that connect the Vercors plateau to surrounding valleys. Cyclists can enjoy a scenic ride along the Lac de Monteynard trail, which offers dedicated bike lanes and stunning lake views.


4. Best Time to Visit

Season What to Expect Why Visit
Spring (April‑June) Snow melt raises water levels; wildflowers bloom along the shoreline. Ideal for photography, gentle hikes, and bird‑watching.
Summer (July‑August) Warm weather, calm waters perfect for paddle‑boarding, kayaking, and swimming. Peak season for families and water‑sport enthusiasts.
Autumn (September‑October) Golden foliage on surrounding hills; cooler temperatures. Excellent for trekking and capturing dramatic sunrise/sunset shots.
Winter (November‑March) Snow‑capped peaks; the reservoir often freezes partially, creating a serene, icy landscape. Great for quiet walks, snowshoeing, and enjoying the peaceful atmosphere.

Overall, late spring to early autumn offers the most diverse activities, but the dam’s dramatic backdrop makes it worth a visit any time of year.


5. What to Expect

Scenic Walks & Panoramic Views

A network of well‑maintained footpaths circles the reservoir, ranging from easy 2‑km loops to more challenging 8‑km hikes that climb to the Cime du Vieux‑Roche viewpoint. From the top, you can gaze across the lake toward the towering Massif du Vercors—a postcard‑perfect panorama that’s especially striking at sunrise.

Water Activities

The lake’s crystal‑clear surface is a magnet for water sports. In summer, you’ll see locals and tourists alike gliding across the water on kayaks, paddle‑boards, and pedal‑boats. The dam’s regulated flow also creates safe zones for swimming and family picnics along the sandy shoreline.

The “Passerelle du Lac” – A Must‑See

One of the most Instagram‑worthy attractions is the Passerelle du Lac (Lake Bridge). This sleek, cable‑supported footbridge stretches across the reservoir, offering a unique perspective of the water below and the dam’s massive concrete wall above. The bridge is fully accessible, making it a great spot for all ages and abilities.

Wildlife & Photography

The surrounding wetlands attract a variety of bird species, including kingfishers, herons, and the occasional golden eagle. Early mornings are prime time for bird‑watchers, while the ever‑changing light conditions provide endless opportunities for landscape photographers.
