Mrzli Vrh, Mountain summit in Tolmin Municipality, Slovenia

Mrzli Vrh is a 1359 meter summit in Tolmin Municipality with far-reaching views across the landscape. The outlook spans the Soča valley and the surrounding Julian Alps.

This mountain was a key fighting zone during World War I, where Italian and Austro-Hungarian forces battled starting in 1915. That intense period left deep marks on this mountain area.

The mountain's Slovene name, Mrzli vrh, means "cold peak". In June 1915, after the first Italian assaults failed, Italian troops were convinced that local people had betrayed them and carried out a decimation, killing six civilians. The summit stayed in Austro-Hungarian hands throughout the war, and the trenches and defence lines on its slopes made it one of the most heavily fortified positions in the Soča valley.

The hike starts from Krn village at 840 meters elevation and follows marked trails through forest sections to reach the top. The walk takes around 90 minutes and needs sturdy shoes.

Near the summit sits Puščavnikova jama Cave, which requires a flashlight to explore inside. Within its passages you can find rock formations and traces of military activity from past conflicts.
