No special access issues
Coming from Mayrhofen, go South following the indications to Ginzling and reach it (a little bit more than 10 km). Now you have to keep driving along the valley towards Schlegeis reservoir.
Drive over the Ewige Jagdgrunde crag, then take the road to the left to reach the car park of the Breitlahner inn. A ticket payment is required.
From the car park, take the dirt road going south heading to Berliner Hutte. Cross the first bridge just after the car park, at the first junction go straight. Shortly after a huge bend, there is a crossroad.
The Dolby surround sector is close to this point (5 minutes from the car park).
Go left to get to the boulders of Breithlahner wald (10 minutes from the car park to the first boulders), while go straight (Berliner Hutte indications) to get to the Klausenalm area (20 minutes). Trails are reported in the topo.
