If it’s a nice day (which it will be if you are going for the first time) and if a weekend expect a lot of traffic in the Le Touquet area and circuit ...mostly arriving from the UK from different directions with all sorts of “joins”.
They can appear from anywhere. Keep an extremely good lookout.
The standard of airmanship can be appalling!
Dont file the flight plan more than a day in advance as many are getting lost over there recently. You can file the return flight plan before you leave.
Allow plenty of extra time for your return as NW closes strictly at 7 pm and, if Le Touquet is busy, there is often a delay in getting away.
