Biogradaska is a primeval forest and there are no trekking paths at all. The only way is to follow the river-course for 8 hours till the spring. Actually the river forms a delta whith many branches flowings into the lake; on the left (looking at the spring) there is a false way branch because is "another" different torrent. Finally, after long researces, I found the main stream of Biogradaska river (but I was alone and was caming on darkness... so I stop there). Full diary [English] [Italiano]
