The forest stands of Arolla pine below Smrekovcem, which are declared natural assets of national importance, are on Končnikov vrh (NW of Krnes) and on Presečnikov vrh, east of the pasture or saddle Bela peč.
Interesting that you mentioned the data for Peca. According to literature it should be a few individual trees on the northern slope, probably remnant of a former stand. The location given is cirque Križe, between Kneps and Bistriška špica, at approx. 1800m a.s.l.
