I agree with Gerund - always given that you stay within limitations with which you feel comfortable. For example, the first time across the Channel in anything other than perfect conditions you might find there is more instrument flying than you expect and one or two new procedures with ATC and flight plans. If you are not sure, go with someone else maybe the first time. Northern France, particularly around L2K with a service from Lille is very friendly and every bit like out LARS service. However further south flight information services often do not really exist in France. Again it is not a problem but the first time you might feel a bit uncomfortable. Finally never count on the weather. As you go further afield count on occasionally becoming weather bound despite all the best plans. Not knowing where you are based, and subject to this, for European bound adventures I reckon a conservative plan might be to do L2K or the CIs first time out, and then maybe down to Paris, after which you should feel comfortable going further afield!! Also talk to as many people as you can who have experience flying in Europe - apart from the simple stuff, the flying, there are a few tricks to learn to make the whole thing less frustrating - for example it is surprising the number of places in France that do not accept credit cards for fuel - a bit of a nuisance when you have not got enough cash or a Shell card!
