Ascent to Mt. Mrzli vrh from the village of Zatolmin is appropriate for fitness training and is very convenient due to its vicinity to the town of Tolmin. You can make it quite faster than this is defined in this description. If you would like to enjoy in more comfortable hiking pleasures, or take your family or a group of friends to the top, I recommend you to arrange transportation to the Kuhinja Mountain pasture (beneath Mt. Krn) and take a considerably gentler ascent across the Pretovč Mountain pasture from the side facing the town of Kobarid.
