This is a gripping book which will leave you wondering what drives human beings to face the dangers and pain associated with K2. An essential read if your heading up the Baltoro glacier. The KKH is the starting point for many treks in the Karakoram. To see the largest selection of possibilities I recommend the Pakistan trekking guide as it provides most comprehensive trekking guide available for the Karakoram and Hindu Kush. The authors have really been off the beaten track to provide detailed and accurate descriptions of routes throughout the heart of this mountainous region.
Nothing seems to have been missed.
Good route maps are also included. A Pakistani trekking company based in the Hunza valley.
