The first ascent of the route "Nisteia" (45° M3, 300m) was realized in 2003 by T. Hatzisyrlis - S. Stamatiou.
The route starts in the same way as the summer route "Agriofraoula", but then it moves on the right side of the gully. It goes on following a narrow snow line, between the rocks, while it is pretty vertical and therefore the conditions are usually very good. A bit before reaching the end, it meets with the route "Agriokatsiko" and then it continues for a while to the right, and finally comes out through the smallest part of the cornice.
Caution is required during the beginning of the 1st pitch because there is a huge hidden bergschrund.
In order to climb the route, the necessary equipment consists of a set of friends (small - medium), a set of nuts and some pitons.
