If you use a GPS and can’t find “Natur-Ferienpark” (The LAN park), look for the street “Zur Warte”. Once you’ve arrived there, follow the road to Birkenallee (another road). The LAN then is to your left (loads of cabins).
Advice from foungi from having been there: “just drive up the hill”
If there’s lots of red brick houses to your left, stop!
