From Predela, it reaches the main ridge of Pirin via the hut Yavorov and follows it via the three highest peaks of Pirin (Banski Suhodol, Kutelo and Vihren) and the ridge Koncheto, before descending to the Vihren refuge. It continues on the ridge until the Vinarska Porta saddle, and then runs along Tevno Lake and down the Zhelezina stream towards Pirin hut. From there it is the only marked trail leading through the Central Pirin range, passing the peak Orelyak and the hut Popovi Livadi. It ends at Petrovo near the Greek border, where a bus to Kulata on the border can be taken. Total length within Bulgaria is 250 km.
