Gjeravica (2656 m) is located in the west of Kosovo.
In winter time - when we placed the box - the tour to the top of Gjeravica is not easy, depending on the wheather conditions you need mountaineering equipment. In summer time the walk is not so difficult.
More specific info can be found at:
I hope the box is available nearly all year, but with lots of snow it probably will be not.
I lost my waypoint, coordinates may be off a little bit, but you will be easily able to find the box with help of the hint and the spoiler picture - it is very close to the top.
