The far north: limestone mountains, a road that switchbacks along the Chinese border, and markets where the surrounding valleys come down to trade.
Give it four or five days for the loop.
Our suggestion, not a rule.
Go if…
- You want the scenery that made you consider Vietnam in the first place.
- You are comfortable on a bike for several days running — or happy to ride behind somebody who is.
Maybe not if…
- You are not a confident rider and do not want to be a passenger. The road is the point of the place.
- You need reliable comfort. This is the least polished thing on the list.
The bit people get wrong
People underestimate two things: how tiring several consecutive days of mountain riding is, and how cold it gets up there. Going as a passenger with a local rider is not a compromise — for most visitors it is simply the right way to do it.
Goes well with Hanoi.
