Haroon is correct. Is taraf se tu naran ka route theek rahega but wapsi may Chillas se Babusar Top ki charhaye bohut zyada hay aur FX ke liye ye charhaye apko mushkil may daal sakti hay.
Secondly I don't know route from Gilgit to Chitral is kind enough to travel. But I do know u will be again in trouble if u must have to follow Lawari Top route in case Lawari Tunnel is closed. And for your info I have heard Lawari Tunnel is closed most of the time. So you have to plan well.
