This is where you will have to arrange porters, donkeys and horses. To give u an idea about the costs- About 800-1200 per donkey per station, 1800-2000 for a horse with a little room for bargaining. But then these are absolute essentials. You wouldnt be able to make through without them.
Before starting off, take as little items with u as possible. Load most onto the donkeys as soon some of the less experienced ones will find themselves fighting for breath with aches and pains begining to creep. Progress should be as slow as possible and no need to rush into things. Make frequent small stopovers for rest and intake of fluids. For some it may slowly prove to be a gruelling contest but then thats the beauty of this part, Pain and pleasure going along all the way till the end.
