There is a 501 bus directly from the bus station in the city, about half an hour's drive. But it is necessary to note that there are very few departures in winter, so check the timetable in advance. Accommodation is very expensive, that is, the tour ticket is more expensive. But it is still very worth a visit. All the buildings inside are made of ice, and each room is completed by different designers. When I went there, I was lucky to compare, and I saw a very late glow when I left later, and I saw the aurora at night.
