Winterwanderweg from Oberwald to Niederwald
This path runs through the snow covered fields and along lanes from the head of the Rotten (or Rhone) valley for about 20km. It's probably best to tackle the walk over two days as walking through snow is surprisingly tiring. The great advantage of the path is that it follows the route of the Matterhorn Gotthard Bahn (of Glacier Express fame) so there is an hourly service stopping at every station. If you get tired or run out of time there's a station abouty every 2 or 3 km. Niederwald, Blitzingen, Biel, Gluringen, Reckingen, Münster, Geschinen, Ulrichen, Obergesteln and Oberwald all have halts, and restaurants nearby if you have to wait for the train. In places the the path parallels the Langlaufloipe, or cross country skiing tracks but in other sections it strikes off on its own.
