Well, it is only the Pakistan part of Hindukush. This is by far the best travel book about the region which I found to be the most challenging for trekkers of all the places I have visited. I used it on two journeys to the Karakorum. The book contains besides the obligatory historical and cultural insights the description of the most outstanding treks in condensed form. For me and I think for most trekkers, the most important informations are what the demand and the highlights of the tours are and how to get to it. If you have to turn right or left on a certain stage is not what you are going to read when you are already on the way. Much more important are good maps since there is also a deplorable lack of maps on this mountain area. This book has a good collection of drafts. But taken into consideration that the treks had been done by the authors it is sometimes a little disappointing that they missed to go more in detail. The number of days for a trek is very much depending on your physical fitness. I did all the treks in a shorter time than proposed, which should be known beforehand for better planning. Also that the authors did not dare to tell us more about their subjective impressions. If not here, where else? If you have not seen the Karakorum, you missed the most impressive mountain scenery Nevertheless it is the best what you can get about this remote and neglected mountain area.!
