The best way to get there is from the road, although there is a nearby road from which you could get there, but since the road is all plowed it is a better option. You have to climb the slope and you walk less. Once you go up you can see it well, from below it cannot be seen. It is a fairly large fort where you can see the walls and where the outbuildings were, with a little imagination you can also see the corner towers that made up the defense.
Once you are up there you understand why that location is. It is not very high and yet there is an excellent panoramic view of all the surrounding towns and lands.
