Hmm...Kop is great mountain but your demands for nordic ski tracking are "negative"...there are some tracks named "crvene bare" but I have never heared that someone ever been there...And don't be to smart to try it 'cause you can lost yourself at the bottom of the world In the other hand the snowkiting is suporeted on Kop...One of the wellknown ski instructor is the pioneer and best guide for that discipline...I think his name is Drago,so when you came - ask for him...Anyway You should came to this mountain and february is the perfect time (snow and wind) .
