The Tolminka troughs

Located at 180 metres above sea level, the Tolminka troughs are the lowest-lying point of the Triglav National Park and one of the most important natural sights of the Municipality of Tolmin. The fact that the wild canyons of the river have long attracted visitors is confirmed by the legend saying that the gorge was also visited by the famous Dante Alighieri who, impressed by the mysterious troughs, wrote the Inferno (Hell) of The Divine Comedy with the Tolminka in mind. The path through the troughs was first arranged by the Tolmin Tourist Association in the period 1953-58, whereas later the maintenance of the trail was taken over by the owner of the bar located at the entrance to the gorge, and since 2006 the trail has been managed by the Sotočje Tourist Board. In 2006 the path was reconstructed, repaired in several sections and equipped with several information boards and posts.

The Tolminka troughs at the entrance to TNP can be accessed by road from Zatolmin towards the village of Čadrg. The trail through the troughs is not long and although it is protected, caution is required in certain sections. The entrance fee charged is collected by the Sotočje Tourist Board and intended for the maintenance of the trail. The visit to the Tolminka troughs, with stops at information boards and a detour to the Zadlag or Dante's Cave (Zadlaška jama) takes about one hour.
