Hi Mlucas!

Do you want to see the House of our Santa Claus?
sounds good! indeed!
Ustyug is northern city and I think you should plan trip on winter months because it will be more funny and interesting. In winter you can
play in snow,
ride on a sled (with dogs, horses or reindeers),
skate on ice
see churches under snow - it's wonderful.
and of course our Santa Claus (Дед Мороз) and his house.

any way Ustyug is not a big town, its population is about 30 000.
And take warm clothes! It is about - 15 C in winter
