Where is it? So there is no mistake. Volontar doesn't even have it written on his own website that he is a mountain guide. Sloppiness happens on our forums, where one is smarter than the other. The loudest lead and thus do considerable damage to the reputation of mountaineering web content.
@zebdi, I know what the designations of Hiking guides mean and also what the difference is between Hiking and Mountain guide. And precisely the latter is obviously a puzzle to many.
Hiking guides are also qualified for leading, nevertheless they don't have the mountain guide license, which is so gladly mentioned here.
