Agree with everyone L2K is a great place and one of my favorite day trips. I go there several times each year.
Not long after passing my PPL I to had to get a SVFR to leave L2K. The first I got told of this was I think at the hold but may have been with the taxi instructions. Odd SVFR for us means an increase in minimums. Does anyone know what the difference is for France.
Also L2K know require a transponder to enter their zone.
On occasion although probally not this time of year if you arrive in the rush hour sometimes they get all aircraft to orbit over Boulogne and call you off from there.
Have fun
