you have to see how much Snow fall this season - as this year - very early snow start falling
normally - roads are open in April - though babu sar pass not open till July and Glaciers remain till mid july on ward from Naran
There are lot of Hotels in Naran - depending upon budget
I suggest PTDC Motel Naran Due to its location on bank of River Kunhar and large lawns and resonable rent
Each type of car suiting your needs are available from Lahore
