I'm thinking of booking on the above tour either late this year or early next. Can anyone tell me how much hiking/walking is involved though, particularly in Sapa. I have a slight disability with one of my legs which isn't a problem in the normal course of events but if there's too much clambering around then I could have problems. To put it another way I wouldn't be able to do a trek but even quite long walks over uneven surfaces are fine - just no jumping over streams or clambering over rocks!
Any info you can give me will be fab!!
Thanks in advance.
