- Day 3: Vihren hut – Tevno Lake shelter: The most panoramic part (6-6.5 hours). The hike winds through high mountain saddles and lake cirques to the iconic shelter.
- Day 4 and 5: h. "Tevno lake" - h. "Pirin" - "Popovi Livadi" town: Descent to Pirin hut (4 hours) and the final, gentler stage to Middle Pirin (7-10 hours), where the rocks give way to forests.
