Perhaps one or two smaller European workshops, specially if their dates are on a weekend. I very much liked the London Perl Workshop, and if there's one this year, I'll try to make it there.
Is there a web site that lists all planned conferences/workshops? That would be extremely convenient.
YEF has the dates! (Score:2)
The YAPC Europe Foundation has the dates of the conferences [yapceurope.org] and workshops [yapceurope.org].

Check out the left column on www.perl.org/events.html [perl.org]. I think that should help, though it's dependant on Robert Spier's knowledge of the event. If he doesn't hear about it, it doesn't get posted.
