From Wiki regarding the excellent Vrsic Pass:
The road through the pass rises from Kranjska Gora in a series of 50 hairpin bends, traverses the top of the Vršič Pass, and descends into the Soča Valley. The upper elevations of the road are rendered impassable by heavy snowfall during much of winter. The road was greatly improved in late 1915 to supply the Isonzo front of World War I, and it was originally named after Archduke Eugen of Austria-Hungary. The current name, Russian Road (Ruska cesta), refers to the approximately ten thousand Russian prisoners of war used as laborers in the 1915 construction.
Just off the main road, on the north side of the pass, at an elevation of around 1,200 m (3,900 ft), there is a Russian Orthodox chapel, built by the Russian POWs to commemorate their comrades who died during the road construction.
On the south side of the pass there is a bronze monument in honor of the mountaineer and writer Julius Kugy, work by the architect Boris Kobe and the sculptor Jakob Savinšek. It was erected in 1953.
It is truly beautiful & belies the painful history.
From memory I stayed in the Hotel Vitranc in Kranska. No problems.
