In reply to chick mackay:
I was in Triglav National Park earlier this year. We drove in from Mojstrana, a small village just west of Jesenice. Theres a road that takes you all the way up the valley to the refuge, how possible this will be in winter i dont know.. The roads pretty steep! However there is a marked trail from Mojstrana to the Refuge, thinks its about 20km of the top of my head.
We never actually got chance to climb the face unfortunately, the weather was poo. However we were told that the rock is generally ok with a few friable areas, its also general practice to take a shed load of pitons along too. Even in summer.
As for bivvies, i wouldnt. Stop in the refuge at the road head the night before, and make sure you do your route in a day. Theres 2 further refuges on the summit of triglav where you can spend the night.
Ive got a topo of the classic northface route "KRATKA NEMSKA" 1 move of IV, the rest II/III 800 m, 20 pitches.
Let me know if its any use to you and i'll email it over.
