In reply to Glenn Sutcliffe:
This is the guide. It's mulitlingual: https://sidarta.si/en/product/slovenia-climbing-guide-en/
Generally a good guide, but note - the "maps" showing how the get to crags are not scale maps - you need to go by the times as sometimes distances are compressed! (or find a pin on GPS). I sometimes think the directions are written as a reminder assuming you've been one
Depending on when you're going...
If it's spring/summer, then Senica is the best local crag, with a good range from 5+ to 7c.
Drnulk is good on a hot day. Nadiza is ok.
Lutne Skale has a lot of routes, all facing different angles. Not good if it's too warm and humid, but you can usually find a cooler face. Some great looking harder lines that I've not tried yet.
Tolmin is a lovely place, but it's not really the climbing hotspot of Slovenia. There's a range of decent, but not world class, crags within 30-45 mins. The 1.5hrs+ there's a whole heap more.
Down south, the main crags of Osp and Misja Pec - not great in summer, but two of the better Slovenia crags. Further east you have Bohinj.
Grades are generally tough in the 5s, 6s and low 7s (1.5-2 letter grades harder than most other places). I guess they even out at some point above 7b...
I heard there's some good multi-pitch up by Mangart - not been yet.
Swimming, cycling, river canoeing/kayaking etc. are all good too. The paragliding is apparently world class!
Oh...forgot to say - Vipava and Vipavska Bela are meant to be good, not been. About an hour away.
