1. Discover the red ruffes, a unique lunar landscape
The first wonder of a visit to the Lac du Salagou in the Hérault region is undoubtedly the bright red earth. These geological formations, known as ruffes, offer an extraordinary spectacle, worthy of a Martian landscape. Made up of fine clays and sandstones enriched with iron oxide, these sedimentary rocks date back to the Permian period, around 250 million years ago. At that time, the region was at the heart of the supercontinent Pangea, with a tropical climate.
The striking contrast between the intense red of the ruffes and the deep blue of the lake creates a palette of colours that is absolutely unique in France. Photographers and nature lovers flock to capture these exceptional panoramas, which are particularly magical at sunrise and sunset, when the low-angled light intensifies the purple hues. There are several trails that take you right up close to these remarkable formations, allowing you to fully appreciate this unrivalled geological wealth.
2. Visit the village of Celles, witness to a deeply moving history
When exploring the shores of Lac du Salagou, it’s impossible to miss the village of Celles, whose poignant history fascinates all visitors. When the dam was built in 1969, this medieval village was destined to disappear completely under the water. Its inhabitants were expropriated and several houses demolished, but in the end only part of the village was flooded, leaving only the surviving buildings standing.
Now classified as a protected area, Celles is undergoing a veritable renaissance thanks to rehabilitation projects. Wandering through its quiet streets is a moving and relaxing experience. Its Romanesque chapel, stone facades and panoramic views over the lake bear witness to the region’s rural past. This abandoned then reinvested village is a perfect symbol of resilience in the face of upheaval. If you’re visiting Montpellier and the surrounding area, Celles is a must-see, steeped in history and authenticity.
3. The Salagou dam, a technical feat at the service of irrigation
The construction of the Salagou dam was an ambitious project launched in the 1950s and completed in 1969. This 63-metre-high structure, built of earth and rock, holds back the waters of the Salagou river to form a 750-hectare reservoir. Its initial purpose was twofold: to irrigate farmland on the Hérault plain and to control the devastating floods that regularly hit the region.
Today, the Salagou dam still plays an essential role in the department’s water management. Visitors can observe the dam from a number of vantage points, and discover educational panels explaining how it works and its history. This impressive infrastructure blends harmoniously into the landscape and is a testament to 20th-century French engineering. When you visit Lac du Salagou in the Hérault department, take the time to appreciate this technical achievement, which has shaped the entire surrounding area.
4. Hiking and mountain biking trails
For hiking enthusiasts, a visit to the Lac du Salagou in the Hérault is a real godsend. The site offers a multitude of signposted trails to suit all levels, from casual walkers to seasoned hikers. The complete tour of the lake covers around 28 kilometres and can be completed in a day for experienced hikers, or in two days with an overnight bivouac.
The routes allow you to discover the diversity of the landscape: hills of red ruffes, wooded areas, wild creeks and spectacular views over the water. Mountain bikers won’t be left out either, with a host of technical routes winding their way through the rugged terrain. Whether you’re on foot or by bike, every diversions has its own surprises in store: unspoilt Mediterranean flora, migratory birds and breathtaking views. Don’t forget your camera to capture these unique moments!
5. Water sports on the waters of Salagou
Over the years, Lac du Salagou has become one of the Hérault’s leading water sports locations. A number of leisure centres on the shores offer a variety of boats for hire: pedalos for families with children, canoes and kayaks for exploring secluded coves, windsurfers and wingfoils for water sports enthusiasts, and electric boats for peaceful cruising.
The regular wind conditions make Salagou a popular spot for windsurfers and catamaran sailors. Lessons and courses run by qualified instructors allow beginners to learn in complete safety. Stand-up paddling is also becoming increasingly popular, offering an original and zen way to discover the lake.

The calm, shallow waters near the shore are perfect for younger children, while more experienced swimmers can venture further afield.
It is important to respect the regulations in force: dogs are allowed on a lead around the lake, but may not swim near the supervised areas. Motorised vehicles are prohibited to preserve the tranquillity of the site and protect the ecosystem. After a morning’s hiking in the Mediterranean sunshine, there’s nothing like a refreshing dip in the waters of Salagou, against a backdrop of the glowing hills that make this area so special.
7. Explore the nearby Cirque de Mourèze
Just a few kilometres from the Lac du Salagou lies the spectacular Cirque de Mourèze (34800 Mourèze), an absolutely fascinating dolomitic chaos. This exceptional natural site features a maze of astonishingly shaped white rocks, sculpted by erosion over millions of years. Some of the formations evoke human or animal silhouettes, stimulating visitors’ imaginations.
There are several signposted footpaths leading through the heart of this mineral labyrinth. The hike up to Mont Liausson, the highest point at 535 metres, offers breathtaking panoramic views of Lac du Salagou, the red ruffes and the whole surrounding region. This loop takes around 7 kilometres and 2 to 3 hours to complete, and is suitable for walkers in good physical condition.

It’s a 30-minute walk from the village of Mérifons.
The summit of Mont Liausson offers an absolutely exceptional 360-degree panorama: the lake, the Cirque de Mourèze, the surrounding vineyards and even the foothills of the Cévennes on a clear day. These viewpoints are particularly popular with photographers in search of the perfect shot. The light at the end of the day sublimates the landscape and creates an almost unreal atmosphere. Bring good walking shoes, as some of the access points require a short climb, but the effort is always rewarded with unforgettable views.
