Getting ThereFor the south approach you have to follow the road until Matrei, then the valley Virgental to the village Hinterbichl, 1329m. Here you park the car by the houses in the village or you drive some 500 meters from the village and then on the crossing turns to the right and over the road you reach the larger parking place near the stone-pit. You can take a taxi to the hut Johannishütte, 2121m or you simply walk by foot all the way to the hut over the macadam road through the beautiful valley called Dorfertal.. One nice possibility is also with the bike.
From the hut Johannishütte we continue over trip to the next hut Defreggerhaus, 2962m. From the Johannishütte we first cross over the small brook and then we start ascending over the nice grassy and rocky slopes. Here we will see many marmors. Or if we have a bad luck we will only hear them. We ascend higher and higher and soon we come to the spot 2802m where we for the first time see the hut. Over the scree and rocks we reach the hut. If we are on the two day trip I suggest to ascend the same day some meters higher to the ridge where we can see the long glacier Inneres Mullmitzkees.
From the hut we go some 100 meters to the ridge where we make a glacier rope and we descend a bit and then we cross a big glacier also called Rainerkees. We have through the whole year nice wide path in snow all the way up to the pass Rainertörl, 3422m between Hoher Aderl, 3504m on the left and Rainerhorn, 3560m on the right. We must be careful on the crevasses.
We can see Rainerhorn in the east direction. From the pass we continue over the best passages in the steep snow slope all the way to the summit of Rainerhorn.
Essential GearIce axe, ropes and crampons are necessary because the glacier is full of cravases.
With ski, most mountaineers don't use a rope, but everyone has to decide this on his own. Ice axe and crampons at normal conditions not necessairy.
