Great A/A French airport. Check air club website for more information (e.g webcam, wind->runway): https://achr.asso.fr/ I have frequented this airport to go to Basel. the cost of taxi is prohibitive in the other direction (Basel to airfield, around 100 CHF). Landing fees could be paid during the operational hours, otherwise I think they don't bother. If not French, try with German if you can (air or ground). The office door has a number to close the flight plan, but it didn't work for some reason on my last visit. FIS called me for that.
