I have a question that is very similar "Hanoi to Mai Chau by motorbike" but for Mai Chau to Son La.
A friend and I plan to go from Mai Chau to Son La by motorbike (around 190km). Each of us will drive a Honda Win 110cc. As for the other related question I have only found a couple of articles mentioning this route so I'd just like to get feedback from more travellers.
The QL6 national road seems to be the simplest way to do this journey, however I wonder if there is more convenient route (e.g. less traffic, or better scenery)?
