Castelar de la Groa was a stronghold of the fortified line that climbed Monte Bondone. The easy route starts from the Camponzin pass, and is equipped with signs and illustrative panels. From the parking lot, walk towards the asphalted road and from here follow the signs indicating “Route of the Great War”. At the first fork, continue on the road to the right which reaches the top. Arriving at the northern end of the hill, you descend into the woods, where many field works are now buried by vegetation. The military road ends near a stol. From here it is possible to walk along a stretch of trench and then reconnect to the path. Following the signs you quickly return to the parking lot. Shortly before arrival, abandoning the path and going down to the right, you can visit the long trench lower than the stronghold.

The VI sector of the Fortress started near the town of Sopramonte and reached the top of Monte Bondone.
