Parking lot at the Planica NC
It is best to be done in late winter. There is a road that goes to Dom v Tamarju hut. If the road is dry you can walk in hiking shoes or even ride a bike to the hut (car is not allowed). Or skin up to the hut. From the hut go further up the valley on skins.
You will see a narrow ''almost gorge'' named Jalovčev Ozebnik. There you should go. Keep in mind that Jalovčev Ozebnik is very exposed for avalanches and falling rock - you need to be an early bird to be on the safe side.
Once you get out of the Jalovčev Ozebnik turn right and see if the conditions are good to go to the summit. Please keep in mind that the part from the plateau to the summit is very dangerous and you need to be a very experienced snowboarder or skier to ski down. You can choose to just hike to the summit leaving your gear at the top of Jalovčev Ozebnik.
Best to ski down the same way you came up (from the plateau). Through Jalovčev Ozebnik you have to be observant to others who may be still ascending. If it is empty you can have fun. But, as mentioned, be careful for some avalanches and falling rocks from the walls. Enjoy!
