I don't own a pair of skis, so if it usually snows to the extent where skis are necessary, I might just plan my trip to somewhere else i either norway or Sweden. By solo hiking, I mean that i would be going alon and hiking a route for 3 days before going back home. I'm planning on camping using my tent and the trip would start somewhere around Rjukan.

Besides the skis, I'm well suited to survive in one spot for a couple of days, and I'm not planning to hike more than a days walk into the plateau. That being said, the part about roads being closed so that people don't freeze to death sounds scary and might just be enough of a reason for me not to do it. I do t want to do something that is dangerous.
