This route crosses private property (Fretheim Gard) and should be marked as private. According to Norwegian law (Outdoor Recreation Act § 2), this is classified as "innmark", with no public access. An uncastrated bull grazes here in the summer – serious safety risk. Please update to access=no and private=yes.

"Sletta" is "dyrka mark", cultivate land, and is not allowed to cross (as described in friluftsloven § 1 a: «Som innmark eller like med innmark reknes ... dyrket mark ... hvor almenhetens ferdsel vil være til utilbørlig fortrengsel for eier eller bruker.», jf. definisjonen av innmark).
