Asif Bhai,
Jeep took about 1:15 hours till Gabral and 1:20 hour more till Shahi Bagh.
This jeep trek is very dangerous and very few tourists visit this place therefore it is still in very good condition.....
We reached @ Jag Banal meadows in 4 hours from Kalam all trekking.
If you take jeep from Kalam for last jeepable point in Bayun then it will take about 1 to 1:30 hours to reach @ Jag Banal.
It is not recommended to visit this area as most of part of the meadows is under cultivation and real beauty is vanished.
