Is it possible to book a place in advance?

At hostels and mountain stations, yes, that’s fine. We don’t accept advance bookings at mountain cabins, but everyone is always welcome. The cabin wardens make sure that everyone has a place to sleep, even when it’s getting full. During peak-season weeks, at the end of July and beginning of August, this could mean a mattress on the floor. Usually there’s plenty of room. If you’re a group of ten or more people, it’s probably a good idea to let them know you’re coming.
