This is the wildest face of mount Damavand... one of the less used routes to get to summit. one long day of hiking would get you to the base of ridge and another long day of scrambling to get on the ridge and from there you got about 4km narrow ridge line above 4000m altitude to get to Takhte Fereydoon camp(camp 2 summer and 3 winter). after that you got a semi-technical mountaineering to get your self from Takhte Fereydoon to the summit. summit route would be a tense trip because you'll have Yakhar vertical glacier in on side and northern glaciers "Dobi-cell and Aroosakha(Dolls)"in the other.it's smart to get to summit and use the southern route to descend.
