Geography
Biscarrosse is a commune in the Landes department of the Nouvelle‑Aquitaine region in southwestern France. It lies on the Atlantic coast, between the estuary of the River Adour to the north and the Arcachon Bay to the south. The commune encompasses both a maritime zone, featuring a long sandy beach (Plage de Biscarrosse), and an inland area dominated by the Lac de Biscarrosse et de Parentis, a large freshwater lake covering approximately 18 km². The surrounding landscape is characterized by extensive maritime pine forests, typical of the Landes region.
History
The settlement’s origins date to the medieval period, with the earliest recorded mention in the 13th century. Throughout the Middle Ages, Biscarrosse was part of the Gascon province and its economy centered on forestry, salt production, and fishing.
During the 20th century, Biscarrosse gained strategic importance as a site for aviation activities. In the 1930s a seaplane base was established on the lake, later expanded in World War II for the construction and testing of German aircraft, notably the Messerschmitt Me 262 jet fighter. After the war, the former military site was converted into a civil aviation facility, known as Biscarrosse‑Parentis Aerodrome (ICAO: LFBX).
Post‑war development focused on tourism, driven by the lake’s recreational opportunities (sailing, windsurfing, fishing) and the coastal beach, leading to significant urban growth and the construction of holiday accommodations.
Demographics
According to the latest available census data (2020), Biscarrosse had a population of approximately 12 500 inhabitants. The population exhibits a seasonal increase during summer months due to domestic and international tourism.
Economy
The local economy is diversified, with primary sectors including:
- Tourism – waterfront leisure activities, beach resorts, and heritage tourism.

Etymology
The name “Biscarrosse” is of Gascon origin. While the precise derivation is not definitively established, it is commonly interpreted to stem from the medieval Gascon biscarròssa, possibly combining bis (meaning “two”) with carròssa (a variant of carrassa, meaning “rock” or “stone”), suggesting a reference to a landscape feature. Further linguistic analysis would be required for confirmation.
