In winter you walk on wet tuber fields and swampy paths. The route takes you over heaths, through forests, past hedgerows and fens and regularly offers beautiful views of the farmlands. The route can be shortened by 8 km by starting at Haren station. At 25 kilometers you can take the bus from Zuidlaren to Assen or Groningen.
