In reply to the ant hill mob:
I've done a couple of little trips to the Julian Alps in Slovenia, mainly walking and via ferrata, although there is plenty of sport about to go at too, which we have tinkered with on days off. Wild Camping is not generally approved of in the area, but self catering accommodation and campsites are very cheap and friendly so you'd be mad to miss out.
We stayed at Camping Kamne, in Dovje Mojstrana near Kranjska Gora, which is good for the mountains, but for bolts you might be better off further south around Trenta and the Soca valley.
Don't restrict yourself to bolts and cragging if you head to the Julian Alps. Its a stunning area, and the scrambles and via ferrata are exciting, some are quite serious, but there are some well protected routes that get in to some incredible situations. Trad on the other hand is VERY serous, rock is crap and the routes are big.
Late season is the best time, as high up can be choked with snow- but this won't be a problem if you are only doing sport I guess.
The Cicerone guide to the Julian alps is good for the walking and scrambling/via ferrata, and Sidarta do an English language sport guide.
