Domaine de Certes-Graveyron, nestled on the Arcachon Bay in the Gironde department, is a remarkable testament to the enduring power of nature and the evolving relationship between humans and the environment. Spanning 530 hectares across the communes of Audenge and Lanton, this protected natural area offers visitors a chance to immerse themselves in a diverse coastal landscape shaped by centuries of history and ecological transformation. Originally conceived in the 18th century by Emery de Durfort-Civrac, the Baron of Audenge, the Domaine de Certes was initially designed for salt production. A network of basins and sluices was meticulously constructed to harness the natural wealth of the area. However, the salt production venture proved to be less profitable than anticipated, and by the 19th century, the focus shifted towards fish farming. Ernest Valeton de Boissière, a visionary with a passion for social progress, transformed the domain into a thriving aquaculture operation, planting pines and championing philanthropic endeavors. In 1984, the Domaine de Certes was recognized as a "sensitive natural area," encompassing 396 hectares of basins, wetlands, agricultural lands, and mixed woodlands. This designation marked a turning point, signaling a commitment to preserving the ecological integrity of the site. In 1998, the Conservatoire du Littoral acquired the neighboring Domaine de Graveyron, a more untamed and intimate landscape, further expanding the protected area. Today, the Domaine de Certes-Graveyron stands as a vast, embanked domain where nature reigns supreme. It has become a sanctuary for biodiversity, attracting over 120,000 visitors each year who come to explore its trails and observe the rich tapestry of life that thrives within its borders. The site is particularly renowned as a migratory stopover of international importance for numerous bird species, including the elegant white spoonbill. The landscape itself is a mosaic of diverse habitats, each supporting a unique array of flora and fauna. Ancient salt marshes, now dedicated to the protection of natural environments, provide a glimpse into the area's industrial past. Wet meadows and salt meadows offer grazing grounds for livestock, while also serving as vital feeding and nesting areas for birds. Woodlands of mixed deciduous and coniferous trees provide shelter and sustenance for a variety of mammals and insects. Visitors can explore the Domaine de Certes-Graveyron via two main circuits: the Certes circuit, which stretches for 9.3 kilometers and takes approximately 3.5 hours to complete, and the Graveyron circuit, a shorter 6-kilometer loop that can be covered in around 2 hours. These well-maintained trails wind through the heart of the domain, offering breathtaking views of the Arcachon Bay and the surrounding landscape. Information panels along the way provide insights into the natural and cultural history of the area. Birdwatchers will be in paradise, with the opportunity to spot gray herons, swans, egrets, cormorants, black kites, and even storks. The Domaine de Certes-Graveyron is home to over 150 species of birds, making it a prime location for observing both resident and migratory species. Lucky visitors may even catch a glimpse of one of the 42 species of mammals that inhabit the area, or one of the nearly 400 species of insects. Beyond its natural beauty, the Domaine de Certes-Graveyron also offers a glimpse into the region's rich cultural heritage. The Château de Certes, built in the 18th century and rebuilt in the 1840s, stands as a reminder of the area's aristocratic past. Although the château is not open to the public, its presence adds to the charm and historical significance of the domain.
