I am staying at Geirangerfjord and Spiterstulen for quite some time during June and was wondering what kind of sleeping bag I would need? I am staying inside in cabins, and by myself and have a kind of average one that I was going to take. Should I buy a really warm, insulated one? Does it get really cold at night at these place? I haven't found much info on the subject, so any help would be greatly appreciated. Cheers!
It may approach, but probably not hit, freezing every once in a while in the wee hours. The cabins we've stayed in all had blankets/duvets and some time of basic heater.
I have ski toured with a DNT group across the Jotunheimen pre-Easter and stayed overnight including Spiterstulen. As I recall Spiterstulen is downhill (lower elevation) from the Glitterheim hut. We did not carry or use insulated sleeping bags. You should only need a sheet style sleep sack. All the "huts" (really nice mountain lodges) are heated and duvets provided. If I recall correctly Spiterstulen is a private hut with indoor plumbing.
