we are staying in Seefeld in January for a winter holiday, 2 couples all non skiers. We would like to take a scenic train ride preferably with a day or group ticket so we can get on and off when we want. We've stayed in seefeld in the winter before so I know about Garmisch, innsbruck, mittenwald and so on. Is there any direction further we could take the train mostly for the scenery seen from the train? Any suggestions?
