From the Matreier Tauernhaus (1512 m) you have to walk 6 km or take a taxi bus (also possible with horses) to the pittoresce hamlet of Innergschloess (1689 m). After a further 1 km walk the even valley ends. Red marked route Nr. 902 leads directly via the Alter Prager Huette (2489 m) and - with very impressive views to the Schlatenkees on your left side - to the hut, 3 - 4 h
Neue Prager Huette (2796 m, 100 places to sleep, guided from mid March to mid May and from mid Juni to the end of September, Tel. 0043-4875-8840 )
An even nicer possibility ist the "Gletscherweg Innergschloess", which first follows marked route Nr. 921 (direction Loebbentoerl - Badener Huette) and then - just after the small lake Salzbodensee - crosses the valley near the ice of the Schlatenkees (some scientific information points) to the Alte Prager Huette where you meet the major route to the hut, 4 - 5 h
Another even nicer way is the following: From Salzbodensee take the path to Loebbentörl (marked) and then cross the Untere Keesboden (the lower plateau) of the Schlatenkees (marked glacier crossing, usually no rope necessary if snow free, but be careful)
In the spring season the best ascent is just on the NW-side of the creek, that means between the 2 summer routes. Safe conditions necessary!
From the hut first even then ascending to the highest stones of the ridge "Niederer Zaun" where the glacier starts. On the glacier in a gentle ascent to the wide plateau of the "Obere Keesboden", passing the Venedigerscharte (3413 m) and - at least more steep - to the summit, 3 - 3,5 h.
There is almost always a track in the snow. Many crevasses!
Rope and ice axe needed, crampons needed if there is pure ice, especially at the beginning of the glacier.
