Dive into the heart of the Étang de Cousseau nature reserve in Lacanau: a wild jewel in the Médoc

Just a stone's throw from your holiday destination, an unspoilt ecosystem awaits you. Nestling between the large lakes of Hourtin-Carcans and Lacanau, the Étang de Cousseau nature reserve is a veritable sanctuary of biodiversity, just a few kilometres from the Atlantic beaches. Accessible by car from the famous 33 bends road, a car park is available between Lacanau and Carcans, providing easy access to this protected natural area. From here, a 7.5km round-trip path invites you to immerse yourself in the heart of the Reserve, through breathtaking scenery.

Cycling enthusiasts are not left out: the reserve is perfectly served by the many cycle paths winding through the lush pine forest. An eco-responsible adventure at your fingertips, ideal for exploring this wilderness gently, while respecting the fragile balance of the ecosystem.

A treasure trove of biodiversity to explore all year round

Protected by the dunes and the maritime pine forest, this exceptional site covers 875 hectares, offering a unique insight into the local flora and fauna, which change with the seasons. As soon as you arrive, the soothing silence invites you to immerse yourself in the heart of this fragile environment. Nature lovers will be delighted by the diversity of the landscapes: peat bogs, wet meadows and ancient dunes form an ever-changing natural tableau.

Meet the living treasures of the Médoc

Under the benevolent gaze of the Landes sea cows, the sturdy guardians of the area, you'll discover ancestral traditions such as gemmage, the technique of harvesting pine resin that has shaped the history of the region. Every visit is an opportunity to observe at close quarters the rare species of migratory birds that stop over here, as well as the endemic plants that populate the banks of the pond. Since 2024, water buffalo have also 'moved in' to the Nature Reserve to help preserve the ecosystem.

Grey cranes, winter guests of honour

Every winter, a spectacular sight comes to life in the reserve with the arrival of the grey cranes. These majestic migratory birds, on their way south, find refuge in this unspoilt setting for a well-deserved stopover. Their elegant silhouettes and distinctive calls echo through the air, providing visitors with a captivating natural scene. Watching thousands of grey cranes land at dusk and set off again at dawn is an unforgettable experience, perfectly illustrating the importance of this ecosystem in the migration of these emblematic species.
