Ridiculously so. Went to a place called Kotateva Park to do snow-shoeing and ice skating in the forest. Had a coffee in a woodland cafe. 10euro for one can of Guinness.
160euro for a 2km husky sled ride. Worth it though with the kids on Xmas day.
3 hours of daylight starts to get to you, though.
Found a little local shop by the apartment and it was a fraction of the prices in the tourist supermarket.
We did it all independently and got it for half the price of a package and for 7 nights. Buses are good.
