The highest and lowest airfield in France (or most northerly and below sea level).
A grass strip two fields from the Belgian border on a very flat area surrounded by rectangular drainage ditches (the photo makes it easier to find). Until 2013 a restricted-use airfield; maybe because of this the visual approach chart is a slightly different format and doesn't list the radio frequency: just use 'club' 123,5. Bicycles available by pre-booking, and taxi companies listed on the website.
