Hi, so as not to open a new topic, I'll just write here
I'd go similarly to you two, sleep in Zavetišče pod Špičkom, then start towards Bavški Grintavec (Path of Friendship) and descend to Soča.
Since the section from Kanja saddle to the top is closed, I'd descend from the saddle towards Bavščica and make a detour over Vrh Brda.
I'm a bit worried about the crossing from the shelter to the saddle. I've put together a route from maps, I wonder if it's approximately ok. Tips for changes are very welcome
If anyone has hiked this recently, please describe the condition.
