thanks dear for your kind words. as far as ur questions are concerned.
Public transport on raikot bridge is rarely available. u may have to wait long. i m not confirm about the timings because we had hired jeep from raikot to all the way long.
u have to manage ur time such that u reach raikot bridge in morning. i suggest one should stay night at chilas and then move to raikot in the morning by hiring taxi.
Nothing is impossible my friend. u can do it but its quite tough path with no water, no shade, no tree and burning heat of sun on your faces but again decision is always urs..
even here in pakwheels some one also did this trek from raikot to FM. dont remember the name..
