Classic skiing here is great. You have to make your own tracks, but once you've set a good 5 km loop you're good to go.

There's no more sunlight, so the window of opportunity to ski during the "twilight zone" is about 3 hours: more than enough time to get a workout in.
Last days of sunlight:
I used swix polar grip wax which worked great in 0 F to -38 F. I haven't tried skiing in temperatures below that because my ski boots aren't insulated well-enough to prevent frost-nip.
