La Vallon Airfield is an abandoned World War II military airfield in France. It is located 13 km north of Istres in Bouches-du-Rhône.
La Vallon was an all-weather temporary sod airfield built by USAAFXII Engineer Command. The runway was 7,800 feet (2,400 m) in length, 300 feet (91 m) wide, and aligned 13/31. The airfield was equipped with an access road was built to the existing road infrastructure; a dump for supplies, ammunition, and gasoline drums, along with a drinkable water and minimal electrical grid for communications and station lighting. Tents were used for billeting and also for support facilities.
When the Americans pulled out in April 1945, the airfield was dismantled by engineers and returned to agriculture. An outline of the airfield remains as agricultural fields in aerial photos today.
