Access to starting point:
At Tauern motorway in Austria take an exit for Bischofshofen and follow the road in the direction to Zell am See. After a little more than 20 km from Bischofshofen, take a left turn for Bad Hofgastein and Badgastein. Continue to Sportgastein and park at one of the big parking places (ski resort area).
An alternative option is a motorail connection between Mallnitz and Bad Gastein via 8371 m long Tauern tunnel. You will shed 150 km one way with this option (along with tunnel tolls at Tauern motorway).
Public transport is also an excellent option (a combination of train and bus).
Path description:
The trail from Sportgastein first crosses the vast Gasteiner-Tal a.k.a. Nassfeld valley. There is a lot of markings in the valley, since there are also many visitors (most of these are leisure walkers, who turn back at the end of the valley or even sooner). Many huts and mountain pastures await you along the way. The first hut is a Valeriehaus at the beginning of the trail. Nevertheless, just after a couple of minutes of walk there is a Schareck mountain pasture (Schareckalm). Soon after on the right side of the trail, there are Moisesalm and Pottingeralm. A trail to Schereck branches off at this point as well. After 5 to 10 minutes a Nassfeldalm and a hut are reached. After 30 minutes you will reach the end of the valley, where a Veitbaueralm is situated. After this point the trail gets steep and ascends along the glacial moraines. In the next two and a half hours of walking uphill you will gain more than 800 meters of altitude and arrive to the Hagener hut (Hagener Hütte, 2446 m).
From the hut head east. From here the trail is not marked, yet it is easy to follow. Just follow the ascending ridge first to a subpeak and finally to the summit of Greilkopf. On a clear day, the eastern part of Hohe Tauern can be seen from the top.
On the way: Valeriehaus (1580m), Schareckalm (1620m), Pottingeralm (1605m), Moisesalm (1620m), Nassfeldalm (1605m), Veitbauernalm (1645m),
Hagener Hütte (2446m)
