Ah cool well im 20 but if you ski well then age doesn't matter, the thing with off piste and steeps is you have to have a ton of experience and knowledge of the areas and the conditions ie whats safe and whats not. Of which i don't have yet but skiing with more experienced skiers will give you the knowledge you need. I wont be skiing again this season because of all my course work but next year im planning on tackling some more of the well known steeps around cairngorm. Anyone who is up for venturing off the piste is welcome to come!
