Le Touq is a lovely place to fly into. Not sure where you are coming from but once you arrive at the Cap (normally shortest crossing point)having been dismissed by Lille who insist you talk to them but then don't answer..., turn right, follow the coast to Bolougne, give Touq a shout and probably, turn left at the estuary for downwind over Etaples. Other directions/runways may apply but that's the normal direction but obviously listen out carefully.
Once you're there, park nicely in the rows as advised or, on busy days marshalled. I have never been stopped taking photos. Go through customs..if he's there..and then pay/check in just inside the building.
Our normal procedeure is a 30-40 min walk into town through the avenue lined with Maison tres cher, lunch in any number of perfect restaurants, walk to the beach then taxi back to l'Aeroport.
Low hassle destination and lovely on a cold, clear Autumn day.
