If its your first time !
I would recommend to directly go to Keran , explore upper neelum there and stay for night. Next day
Go directly to Kel , hike and explore arang Kel , hike back to Kel and stay for night.
Go to Taobat , explore valley and come back to Sharda and stay for the night.
Next Day ,
Explore Sharda university ruins and bazar. And then drive back to lahore. PS if you have time on the way back then do visit Kutton waterfall as well.
DO NOT miss the Arang Kel. Its the best part of Kashmir. Have a good tour :)
