Ancien Aérodrome de Soustons

The closure was due to economic reasons and a strategic change in land use. The local municipality, which owned the land, chose not to renew the lease for the airfield. Instead, the site was repurposed for the development of a large-scale photovoltaic power plant (solar farm), a project considered more economically beneficial.

The site of the former airfield is now the 'Parc Solaire de Léon' (Léon Solar Park). The entire length of the former runway and adjacent areas are covered with thousands of solar panels. The facility, developed by companies like Photosol (now part of Rubis), is a fully operational photovoltaic power plant that feeds electricity into the national grid. The site is an industrial energy facility and is completely inaccessible for any form of aviation.

Ancien Aérodrome de Soustons was a general aviation and recreational airfield, primarily serving ultralight aircraft (ULM), for which it was officially designated as a 'Base ULM'. It was a popular destination for private pilots due to its location in the tourist-heavy Landes region, near the Atlantic coast and the large lakes of Léon and Soustons. The airfield featured a single unpaved (grass/sand) runway, oriented 15/33, with a length of approximately 850 meters. It did not handle commercial or significant military traffic but was an important local hub for leisure flying, flight training, and aerial tourism, supporting the local flying club.

There are no plans or prospects for reopening the airfield. The complete and long-term conversion of the land into an industrial solar farm makes a return to its former aviation use virtually impossible. The infrastructure for the power plant is permanent, and its removal would be prohibitively expensive and is not under consideration.
