This place is on the roof of Norway. It is only accessible by train - the mainline Bergen to Oslo.
Fantastic hotel Finse 1222 with great views over glacier. The walks along the old navvy road are excellent.

I passed Finse on the Bergen-Oslo line and so wanted to get out and walk/ cycle. The DNT hostel is apparently big but homely (and cheaper). Glaciers at your doorstep.
Is this your business?
