Funny, but I actually never made to Nadkrstac. Once I tried in April, then the snow conditions allowed me to reach only the abandoned Prokosko jezero, later in July a nice thunderstorm caught me 30 mins before reaching the peak...
Started from Prokosko lake and continued by instructions by "Forgotten beauty" book. Reached Nadkrstac, 2112m, about 13.00h.
June 15th: Nadkrstac (2112 m) and Rosinj (205x m)
June 16th: Locika (2107 m) and Krsac (20xx m) + Prokosko lake
Nights at Mountain hut Rosinj (1680 m) on Gornji Vakuf / Uskoplje side
At mid-June, still significant remains of snow; meadows blooming with flowers; this is not a mountain for adrenaline, but for perfect relax
