My plan is after completing manali local and solang valley, the next day i want to go to keylong(night stay at keylong 1) - keylong to suraj tal and back to keylong (night stay 2)- keylong to manali back. I am going on 27th october 2018. 1. Can i hire vehicle from manali for this trip? how much will it cost approximately? 2. how to obtain permit for rohtang? should i do it personally or depend on driver?
