hello guyz
i have done K2/ghondogro La trek. as per itenerary it is of 22-25 dayz but it can also be done in 15 dayz. we were on schedule for that but got stuck up in a blizzard at Ali Camp for 5 dayz and also later in Chilas for 4 dayz as the main bridges over KKh were washed away in floods. u all know that story.
anywayz the Wakhan corridor trek is also the same
if u ppl attempt from Darkot/limt traverse in yasin valley it is around 1 week only.
for attempting chiliji pass and Chitibui glacier u require 2 weeks and also army permission (its not a problem tough).
i am sure tis trek would be less costly than that of K2 Base camp coz u can get margins in potters and guide/cook/assisitan cook daily wages as in K2 they r fixed.
to reduce ur expenses u shud take min potters and return tem along the way as the consumed luggage depletes. nagotiate the most wit the potters and guide. also try to take a small group (4 ppl) so that u need only 1 camp and equipment is least.
