Hi
Via ferrata Cheška Hut - Jezerska Kočna - Kokrska Kočna, Grintovec - Dolgi Hrbet - Skuta - Turški žleb - Savinjsko Sedlo, Kranjska Hut - Slovenska pot.
a few weeks ago did this tour, took me 13 hours, start from parking around 7am return at 20h, 45k steps and about 23km. The route itself is very/extremely physically demanding and tiring, as along the path 80% equipped with cables and pegs, need good physical fitness, good luck.
