Partly enclosed by a dune belt, this vast, triangular bay stretches for 80 kilometers in circumference between the <strong>Dune du Pilat<\/strong> to the south and <strong>Cap Ferret<\/strong> to the north.

And with good reason: this vertiginous mountain of sand rises to a height of over 100 m, 102.5 m to be precise (according to the 2020 survey). <strong>Europe&#8217;s<\/strong> highest dune is constantly on the move, and its summit varies between 100 and 117 m depending on the year. From one end to the other, it is 2,915 metres long and 616 metres wide.

Distance: 77 km, for the most muscular of calves!  <\/p>\n\n<h2 class=\"wp-block-heading\">258 steps<\/h2>\n\n<p>That&#8217;s how many steps you have to climb to reach the top of the <a href=\"https:\/\/www.kerhelen.com\/l-essentiel-a-savoir-sur-la-visite-du-phare-du-cap-ferret\" target=\"_blank\" rel=\"noreferrer noopener\">Cap Ferret lighthouse<\/a>. But it&#8217;s well worth the effort! At 52 metres (height of the light bulb), you have a 360\u00b0 panoramic view of <strong>the Cap Ferret peninsula<\/strong>, the <strong>Arcachon Basin<\/strong> and the ocean. Listed as a historic monument since 2009, the <strong>Cap Ferret<\/strong> lighthouse harmoniously combines classic, original elements (reinforced concrete and bricks from 1947) with more contemporary designs (from the 2010s) structured around steel and glass materials.   <\/p>\n\n<h2 class=\"wp-block-heading\">10,000 tonnes<\/h2>\n\n<p>Between 8,000 and 10,000 tonnes of oysters are produced annually in the <strong>Arcachon basin<\/strong> and <strong>Cap Ferret peninsula<\/strong>. With some 700 hectares of oyster beds, the basin is home to 315 oyster farms and more than 500 traditional oyster huts where you can enjoy oysters with your feet in the water. It takes an average of three years for an oyster to reach maturity and reach the market.  <\/p>\n\n<h2 class=\"wp-block-heading\">6,300 hectares<\/h2>\n\n<p>This is the total surface area covered <a href=\"https:\/\/www.kerhelen.com\/bassin-d-arcachon-foret-dexception\" target=\"_blank\" rel=\"noreferrer noopener\">by the forest of the Bassin d&#8217;Arcachon<\/a>. The state forests of <strong>La Teste-de-Buch<\/strong> and <strong>L\u00e8ge<\/strong> et <strong>Garonne<\/strong> are emblematic landscapes, spaces of memory and nature in the Basin. For over 150 years, generations of foresters have succeeded one another in maintaining the durability of the dune ecosystems and the renewal of the woodlands created in the 19th century.  <\/p>\n\n<h2 class=\"wp-block-heading\">1 800 \u20ac<\/h2>\n\n<p>That&#8217;s the price per kilogram of caviar from <strong>Gironde.<\/strong> <a href=\"https:\/\/www.kerhelen.com\/le-caviar-d-aquitaine-lor-noir-du-bassin-d-arcachon\" target=\"_blank\" rel=\"noreferrer noopener\">Aquitaine caviar<\/a> was born in the 1920s on the right bank of the <strong>Gironde.<\/strong> Today, the basin is home to two sturgeon farms for caviar production, one at Le <strong>Teich,<\/strong> the other at <strong>Biganos<\/strong>.
