In reply to Enty:
You could do worse than northern Greece around iraklitsa which is close to kavala, flights should be OK to thessaloniki or you may even be able to fly in to Kavala itself, you'll need a hire car if you fly to thess-niki. There are three good crags 5 mins from the beach in iraklitsa and even a little DWS, also some DWS over on Thassos. Only poss prob is it'll be around 30 degrees but that's manageable if you're keen and get up early, there's also two awesome caves to climb in.
Can give you some more info on routes etc if you want and should be able to hook you up with a local climber or two as well.
