Kolovrat Ridge Road (from Kobarid)

Kolovrat is the Soča Valley's most historically charged cycling road — a ridgeline at 1,114m that ran along the Italian-Austro-Hungarian front line during the First World War, above Kobarid and the lower Soča. The climb from Kobarid gains over 1,000m on surfaced, well-maintained roads that see almost no recreational cycling traffic despite their quality. The ridge road, reached after the main ascent, runs for several kilometres along the spine of the hill with simultaneous views down into the Soča valley and, on clear days, across to the Adriatic coast of Italy. Open-air WWI museums, concrete bunkers, preserved artillery emplacements, and bone-white military cemeteries line the route — cycling through a battlefield that has barely changed in a century. Average gradient of 6.4% across 16km with ramps to 14% makes this a proper Cat 1 effort requiring full preparation, not a gentle historical meander.
