When ascending the Fella, the river valley veers east at Pontebba and continues 10 kilometers east to Malborghetto. From the latter town, Tarvisio is 10 kilometers farther to the east. To reach Tarvisio from the Soča (Isonzo) valley, a road leaves Bovec and continues about 10 kilometers north-northeast before turning west to cross the Predil Pass (1,156 meters). At the foot of the pass is Lago del Predil (Lake Predil). From there, the road continues north again for about 10 kilometers before arriving at Tarvisio. The Predil blockhouse dominates the road about 800 meters east of the pass. The Malborghetto blockhouse lies about 900 meters east of Malborghetto village. The fort is on a mountain spur that looms over the Fella valley.
