Very helpful... But one clarification..Non-commercial vehicles do not have to pay any state taxes. You will have to pay for Manali green tax as well as Permit for Rohtang Pass. Both can be paid online at Tourism Development Council Manali (H.P.)-InformatoryScreen. Apart from this, you need to get inner line permit for Ladakh and it too can be obtained online at LAHDC Leh Permit.
