Médoc Lakes: Hourtin and Carcans, the Largest Natural Freshwater Lake Wholly in France

easy

250 + 100 XP

Behind the Medoc's Atlantic dunes lies the Lac d'Hourtin-Carcans, 18 km long and 5 km wide at 56.67 km2, the largest natural freshwater lake lying wholly in France, and the same size in every season. Its dune shores were pinned down with pine plantings in the 19th century, part of the largest planted forest in western Europe, and the 2,150-hectare dunes and marshes reserve at its northern end was classified in 2009. A greenway on the old timber railway runs through the pines beside it and the Velodyssee follows the dunes behind the ocean beaches.

Before you go

The Maubuisson beach on the lake is only lifeguarded in the summer season; the lake is 5 km wide and gets a real chop in a westerly, so keep inflatables off it.

The dunes and marshes reserve at the north end of the lake is managed by the ONF and has restricted areas - stay on the waymarked paths.

The ocean beaches at Hourtin-Plage and Carcans-Plage have strong rip currents and are only supervised in the flagged zone in summer - never swim outside it.
