We didn't visit Triglav this time Yann as we were based a bit further south in the hope of spotting bears (we didn't). Some fabulous hay meadows too.
We had a brief visit to Triglav on a previous visit a couple of years ago, when we did manage to see quite a lot of different Campanula including C. zoysii. Next time we will allow for more time up in the mountains, maybe I will pick your brains beforehand Yann!
