Kranjska Gora is Slovenia's oldest ski resort. Its first lift opened in 1948, the Vitranc Cup has run here since 1961, and in 1982 Bojan Križaj won a home World Cup slalom in front of what the resort's history gives as 32,000 spectators. It sits in the far northwest corner, a few kilometers from Austria and Italy, at the edge of Triglav National Park, and it is a one-day drive from Belgrade.
It is also a small ski area, and the guide says so. About 20 km of runs is a day and a half for a good skier, so three days is the right length: one day on the home slopes, one on Vogel above Lake Bohinj, and one off skis, from Planica's ski flying hill to a spring that doesn't freeze. For four or five ski days from one base, choose a bigger area.
The plan starts on a Wednesday, in any week outside the holidays. Day one skis Kranjska Gora and Podkoren, day two drives to Vogel, and day three runs from the Alpine Museum in Mojstrana to Planica and Rateče. Friday evening has floodlit skiing if you still have legs. For more of Slovenia, Bled and Ljubljana are in the extras.
