Yesterday 23.6.2021, I went again from Petrov Brdo all the way to Žabiški Kuk. The path to Rodica is snow-free except for the snowfield below Matajurski vrh. On the path, it is necessary to cross three small snowfields, as visible from the photo. All of it can be bypassed via Matajurski vrh and descent along the ridge (towards Rodica) back to the path. The ridge is not technically demanding, but exposed in places, so caution is needed.
From Rodica towards Šija, just before the exit to the Šija ridge, there are also three small snowfields, which can be bypassed without issues. Snow is then only right below the exit to the Vogel ridge, which cannot be bypassed and requires caution.
