Hon Ba mountain road
Thirty-three kilometres of climbing from near sea level to 1,545 m - eighty-seven hard turns and not a metre of descent.
33.3 km up the mountain
What to ride
Three classes of machine actually rented in Nha Trang. Each shows the model offered by the most rental shops - the one you are most likely to find free.
The road covers 1496 m between its lowest and highest points. Nothing extreme, but engine size does make itself felt on a road like this.
What the road is like
From the Nha Trang side the road climbs for 33.3 km and gains 1496 m to the 1545 m high point. There is no straightening it out: 33.3 km of road cover 13.5 km in a straight line, and 87 turns sharper than 60° come one after another.

Know before you go
The road climbs 1,496 m without a single descent and ends at the top: everything you ride up, you ride back down the same way. The surface is not recorded on the map at all - treat that as unknown, not as asphalt.
OpenStreetMap tags and SRTM profile
The nearest fuel station is 2.4 km from the road, at the bottom. Thirty-three kilometres up and the same back is the whole tank plan.
