  • Patrimony and history

    The Gacholle lighthouse

    Located at 1500m inland, the Gacholle lighthouse entered service in 1884. It allows access to the anchorage of the Beauduc Gulf whilst avoiding the dangers of the tip of Sablon. 17m high, it is powered by solar panels and is distinguished by its sector lighting in green, white and red. The Gacholle lighthouse is one of the welcoming points of the Camargue Nature Reserve. An exhibition on the Camargue coast is open on weekends and public holidays and during school holidays from 11:00 - 17:00 / 11am - 5pm, free admission. Two other lighthouses were built: Beauduc Lighthouse (1903) and Faraman lighthouse (1840).
  • Fauna

    Marine Reserve

    The fishing lodgings of the Beauduc Gulf was established in 2013. The goal was to restore this nursery area for fish by creating a "safe area". Covering an area of 450ha and located 700m from the shore, the area is forbidden to all types of fishing, anchorage, dragging and diving. 6 yellow markings enables mark this area at sea. Scientific monitoring is carried out in partnership with fishermen and all the actors of the marine world. The surveillance of the sea and awareness are carried out by officers of the Park.
  • Fauna


    Tellin is a small shell that lives buried a few centimetres on coastal sand, close to the shore. Its colour varies from brown to lemon yellow, through a salmon pink. It takes its name from its two valves spread like butterfly wings when it's washed-up and stranded. In the morning, the tellin shell gatherers collect this bivalve using a small trawling net shaped like a fishing net rake. The exploitation of this resource is subject to licensing in the Camargue. Amateur fishermen, anglers, respect the resource and the instructions (1.5kg / day / person. ; min. size: 2.5cm).
  • Water and rivers

    The sea wall

    During the 19th century, Camargue has faced frequent floods, causing considerable damage. Thus, the sea wall was built between 1857 and 1859 to protect Camargue from sea ingression onto the land during fall and winter which stop any agricultural development in southern Camargue. 2m to 2.50m high, this structure extends over a length of over 40km. It separates the lagoons from the central ponds of Camargue, forming a visual boundary in an infinite landscape.
  • Fauna

    The Sandwich tern

    Terns are long-distance migratory birds which travel thousands of kilometres during their travels. Their final destination is West Africa. The sandwich tern is characterized by a fully black head with a shaggy crest on the neck, a long slightly curved black and yellow beak, an ash gray slender body and long wings. This migratory species, especially present in the sea and lagoons, is observable during the breeding season (spring/summer).
  • Panorama

    The beach and dunes

    Sandy, Camargue beaches extend on about 70km. The coastal dunes which make up the setting are of great landscape and botanical value with a specific flora and rare species of insects. These animal and plant species which have adjusted to the sandy soil, to drought and salt, live in the dunes (lizards, sand lilies, dune grass ...). Rich but fragile, so be careful when you pass not to uproot the dune grass that are hanging on. Accessing the dunes is strictly prohibited, even on foot.
  • Fauna

    The black-headed gull

    The feathers of the black-headed gull is white on the entire body, except for its which are gray and black in the ends, from August to December. The adult is recognizable by the dark spots behind the eyes. Its white head sports a breeding plumage of chocolate colour. Its short beak, sharp and pointed, is red and black at the tip, as its legs and fingers. Its diet consists of insects, worms, crustaceans but also plants and household waste.

    Ponds and salt marshes

    Located in the lower Camargue, shallow ponds are separated from the sea by a sand bar. With intermittent communication with the sea through the valves, these lakes are brackish or salty. Privileged shelters for birds and fishes, they also play an important role in water management. Because of their stretch and the richness in invertebrates, they are areas appreciated by birds, including the Greater flamingo.

    Hydraulic structures

    Camargue is a place of constant exchanges between the sea and the ponds. To regulate the exchanges between these two environments, three openings (or valves) have been positioned along the sea wall. The Fourcade opening is the only functional exchange zone, continuous between the ponds and the sea. It allows the flow of water and fishes and plays a major role for migratory exchanges, wildlife, salt and water levels, fishing, fish rearing and flood management.
