Unfortunately the Planinarski Dom at Zeleni Vir was closed (on a Friday mid September). Great location though!
Planinarski Dom Skrad in Šubetov Most is a nice, comfortable place to stay, a bit off trail, but worth the detour if you're in need for a warm shower. With good weather I would suggest to continue with the next stage. Just below Skradski Vrh Near the church is a great bivy spot.
There's a small grocery store in Brod na Kupi and in Skrad.
