Hallo Niiek,
the best way to get gps-tracks of German St. Jacob-Pilgrimways is to visit the WEB-site of Beate Steger, ways edited by Hans-Joerg Bahmueller:
www.deutsche-jakobswege.de/wege-uebersicht.html
. The Oekumenische Pilgerweg Goerlitz-Vacha ist the way Number 8. Go to it and oben the next site. May be, there are small mistakes in the gps-track, but by our way I don't think so. The way is well merked in the nature.
By Hans-Joerg are only the main ways in the GPS-tracks. If You want to take one of the variants over Muecheln, I (from Merseburg) prefer it, look to my tracks: North-Variante:
www.alltrails.com/explore/map/okumenisch...nte-mucheln-nord?u=m
South-Variante:
www.alltrails.com/explore/map/okumenisch...ante-mucheln-sud?u=m
By hot weather and mighty sunshine or verry windy weather I prefer the south variante, other wise the north.
From Muecheln return to the mainway you heve to take a part of the St.-Jacobs-Way of Saxonya-Anhalt (Number 6 of the WEB-site of Beate and Hans-Joerg.
Buen camino
Volker
