This almost 50-kilometre and three-day-long tour starts in the village of Trenta located in the upper part of the Soča Valley. Park your vehicle at the parking lot in front of the Triglav National Park Information Centre Dom Trenta (in the immediate vicinity of the bus stop). Start walking in the direction of the town of Bovec and after approximately 300 metres turn on the gravel road leading uphill towards the Lepoč Mountain pasture. After a couple of hundred of metres of the gravel road, turn on the gradually ascending marked hiking trail leading across the Trebiški dol Mountain pasture to the junction for the Zadnjica Valley and the Prehodavci Mountain pass. From here on, you can admire the ingeniousness of the constructors of this former military supply road from World War I practically all the way to the mountain hut. The trail does not require great effort and is logically routed to the Zasavska koča Mountain hut on the Prehodavci Mountain pass. After you have refreshed yourself and enjoyed in views of the major part of the Julian Alps (Mt. Razor, Mt. Prisojnik and Mt. Jalovec), continue along the marked and well-worn trail downhill to the Triglav (seven ) Lakes Valley. Along this trail you will have a chance to see almost all of the lakes, however, we would like to ask you not to bath in these lakes because this is the cause of their pollution. After approximately eight hours of walking you will notice the lovely Koča pri Triglavskih jezerih Mountain hut where you will spend your first night.
The next day, start walking towards the Koča pod Bogatinom Mountain hut which you will reach after approximately three hours of walking in a wonderful ambient of high-mountain larches and pine trees. After you have refreshed yourself, continue uphill towards the Vratca Mountain pass (1803 m). From here, you only have to walk for approximately another hour in order to reach the nearby Mt. Bogatin (1977 m) which offers splendid views of almost all of the trail you already made and of course of the prominent Mt. Triglav (2864 m). Return to the mountain pass along the same trail you came from and slowly continue past the ruins of the former military facilities from World War I towards the Duplje Mountain pasture and the nearby Dom pri Krnskih jezerih Mountain hut (1385 m). After an entire day of walking you will certainly enjoy resting at the mountain hut amongst the mighty and peaceful mountain pine trees.
On the third day you will only need fifteen minutes of walking in order to reach the Krn Lake – the pearl among the Slovenian Alpine lakes. Above the lake, the trail starts to gradually ascend to the top of Mt. Krn (2245 m) - the highest summit you will conquer on the entire tour. Just beneath the summit you can refresh yourself at the Gomiščkovo zavetišče Mountain hut where you can also spend the night if the weather deteriorates or if you become too tired. From here, you will descend to the village of Drežnica along the usual hiking trail (you will avoid the Silvo Koren climbing trail because it is too demanding for a descent). After the entire day of walking you will reach the idyllic village of Drežnica in the afternoon, Here you can choose between several accommodation options or engage a transportation provider to drive you to the nearby town of Kobarid. If you are staying in the upper part of the Soča Valley make sure not to miss the last bus to the town of Bovec which leaves at 21:00.
If you believe that daily stages are too long or too difficult you can also prolong the tour to four or five days.
