Bro,1 jerrican of fuel as reserve is ok. dont place these cans inside the Amiigo
A bro above said that astore to Chillas is 3 hours. agreed . but its horrible journey.
Amigo is ok if u know the distances. for example,pindi to gilgit is almost 550 kms on kkh.
Wont suggest u the route from Babusar other wise much shorter n scenic. but do try it on ur way back if its open. Last time to cross it is 4 in the evening. if u move at 12 from gilgit,u can easily cross it. Best way to check that is it open is to take cell numbers of Police walas on chillas Babusar Check post. ull love that route n will c Lolusar lake again. n much safer route aswell.
