This trail crosses Prenj from West to South. From the city of Jablanica, pass over local hills to the village of Ravna and follow the trail ending on an exposed ridge with great views on Cetina rock face – more than 1000 m high. It continues to a green mountain pass Medjuprenje where there are two mountain huts (one is always open). It continues towards Lucine valley, but turns East over Zakantar, a huge karst plateau and a natural habitat of the endemic Prenj salamander (seen only during the night and rainy weather). Zakantar will end below the amazing Tisovica valley which ends on the slopes of Prenj's highest peaks – Zelena Glava. Half an hour from Tisovica there is another mountain hut called Vrutak. The trail leads across Zelena Glava ( 2155m) and Otis summit ( 2093m), and continues to another valley and further to Bijele Vode ( White waters) where you will find another mountain hut and an old shepherd hut (Katun) which serves as a shelter. From BIjele Vode, the trail descends down towards Ruiste settlement and recreation area. Ruiste is a popular destination for Mostar citizens. There you will find two other mountain lodges, a hotel and a small ski center. From here you can get a lift to Mostar, call a taxi or continue towards Boracko lake.
Also there are a couple of other places (Zakantar spring and close by Vrutak hut) where landmines are suspected, but the area is cearly marked. Just respect these signs!
Watch for snakes and mind your steps because the terrain is very rocky.
Waether on Prenj is quite unpredictable. It is not uncommon that it snows during the summer and the temperature drops below zero.
