In reply to Full moon addict:
I'm from Slovenia - I can't say for sure about the conditions next year, but late June is generally quite okay for the via ferattas. There might be some snow left in the shades and gullies, and I'd still take an ice axe (and, yes, sometimes crampons as well) with me. But majority of the route should be already bare rock. There will also probably be some routes that have no snow left.
If you need more info when you plan to visit, send me PM and I can provide you with current conditions.
