I am interested in doing a good nude beach visit in Europe this summer in late July or mid/late August. I will be based out of Germany but I imagine the safest bets would be in Spain, Croatia or South of France based on weather. I am looking for a good balance of men/women (or more women - we can dream can't we?

) and attractive under-40 crowd. I know the beach crowd can change from year to year so this thread may now be a little dated.
I don't mind driving, flying or taking the train to get there. I'd love to get some good photos/footage but that isn't a strict requirement. I'm not particularly looking for swingers or sex.
Any tips?
