It is difficult to distinguish one activity rather than another because it is the whole trip that completely seduced us.
Let us specify that thanks to the kindness of our guide “Bach”, we approached, on several occasions, people of different ethnic groups in the mountains of the north and that leaves us with an unforgettable memory.
As for the centre, the city of Hanoi, and the different sites we visited, we keep images and memories that will stay with us for a long time.
The duration of our stay (21 days), allowed us, for the circuit that you composed for us, to visit each without any stress each site with enough time to make stops and to make unexpected meetings.
This gave us great comfort.
The order of the visits was also judicious because it seems preferable to us to start with the mountains of the North to finish by the centre with a stage in Hanoi which we strongly appreciated.
