Border cross from ski of slope Kanin(SLO), to ski slope of Sella Nevea (IT)

Hello!
Slovenia is not a member of schengen. 
Can I cross the border from the ski slope of Kanin, through the
Prevala valley, to Sella Nevea? 
Or it can be done only by italian and slovenian citizens? I am a
hungarian citizen. 
If i can pass through the valley, till what time can i do during the day? 
Do I need any ID card or passport for the trip? 

My brother took this pictures on the prevala, slovenian side, end of
april 2006.

How steep is the slope?
Is it hard to climb back to kanin? 

In 06/07 season, I want a trip with snowshoes, from Kanin, through the
Prevala valley, to Sella Nevea, and back.
I need infos about border cross on this ski slopes, legal or illegal?
