From the parking area of the mine museum in Maiern/Masseria the designated path no. 9 leads up to the two huts. First, quite steeply to a road which leads to the plateau Senner-and Aglsboden. If you have passed the Aglsboden, the path ascends to the next section of the valley and soon reaches the hut Grohmannhütte.  Surefootedness required!
