No special access issues
Coming from Arco head to Rovereto and reach the large roundabout in front of the train station. Go straight towards Trento and stay on the main road (SS12) till you get to Calliano. If you come from Trento just follow the SS12 Rovereto direction and get to Calliano.
In the middle of Calliano you will find a large exit close to a gas station, having the indications to Folgaria / Vicenza / altopiano di Folgaria. Take this exit and continue driving on the main road till you go over Dietrobeseno village. 800 meters after you will go through a tunnel and you will see the crag in front of you. Keep driving for other 350 meters and get to the car park on the left side of the road, on the large bend.
Walk back along the main road (pay attention to the cars) and climb the guardrail just outside the tunnel. A small ladder leads to the ledge of the crag.
