The trail is partly common with Trail 5. From Saua Funduri saddle (intersection with Trail 20), descend eastward and after 20-25 meters Trail 20 continues to the right (southern part). From here, walk alongside Trail 5. After 50-60 meters, Trail 25 turns left towards Refugiul Funduri mountain hut. Continue descending. After several large switchbacks, turn northeast when you reach the last of them, descending on Muntele Funduri. After 750 meters, change your direction to the east and after 400 meters (100 meters altitude difference in descent) reach Poiana Funduri meadow. Several switchbacks take you 120 meters steeply down through the forest, then on a more gentle slope to the north-east, and then change direction to the east. You reach a meadow in five minutes and in 250 meters you come across Trail 29.
