The area of Mt. Mrzli vrh is arranged as an outdoor museum. Te top of the mountain offers a beautiful view over the former battlefield of the Isonzo Front.

The ridge is crisscrossed with numerous trenches and caves. In a small area, the remains of both the Austro-Hungarian and the Italian first line of defence can be seen. A guide is recommended for detailed information during the visit to the positions of the two belligerent sides, since access to numerous remains is difficult.

Located along the path from Zatolmin towards the alp of Pretovč is a restored trough that was built already during the First World War. In one of the caves along the way from the alp of Pretovč to Mt. Mrzli vrh an altar is set up.

Access: To the outdoor museum at Mt. Mrzli vrh possible from two sides:

a macadam road leads from the village of Zatolmin towards the alp of Pretovč (a 2-hour walk); access from the west possible from the village of Krn.

The path from Krn village coincides with the European trekking path E7 and gradually rises to the alp of Pretovč (an 1,5-hour walk). From there it crosses the pasture above the cheese dairy up to the erosion indentations, where the path turns left and soon reaches the rock faces on the northeast slope of Mt. Mrzli vrh into which the Austro-Hungarian soldiers hollowed out spacious caves. An arranged rest site lies in front of them. The path to the top leads left, past the caves; a cross stands on the top. It takes about 40 minutes to reach the top from the alp of Pretovč. Because the tour to Mt. Mrzli vrh takes several hours of walking it should be planned very carefully.
