It takes 2.5-3 hours from Naran to Babusar Pass and further 2.5 hours till Chilas if road is open till KKH otherwise 30-45 min extra drive is required to reach upper Chilas town due to blocked road near KKH as result of landslide. I don't know whether that section is repaired or not. Anyhow if u go non-stop then it will take around 6-7 hours but definitely people do stay at Jalkhad, Lulusar and Babusar so it may take upto 8-9 hours with few stays.
Lately, quite a few travellers have passed through the area and thousands of poeple visit the valley these days. Pakwheels community may not be even 5% of those and majority even does not know about these incidents. Reason to mention this is that these days there is lots of traffic on this route and it should not be a problem in day time. Rest may Allah Almighty protect us all from such bad incidents.
