There is a mountain pass between Da Nang and Hue that Top Gear once called one of the great coastal roads in the world, and most travelers miss it entirely because the tunnel underneath is faster. The tunnel takes ten minutes. The pass takes an hour and is one of the best hours you will spend in Vietnam.
What the Hai Van Pass actually is
A 21-kilometer mountain road climbing to around 500 meters over the Truong Son range, where the mountains meet the sea. It historically marked the boundary between the old kingdoms of Dai Viet and Champa, and it remains the meteorological divide between northern and central Vietnam — it is genuinely common for one side to be sunny and the other in cloud.
The road switchbacks up from the Da Nang side with the bay opening up behind you, crosses at the old French and American gun emplacements at the summit, then descends toward Lang Co lagoon on the Hue side.
How to do it
Motorbike or scooter
The classic version, and the reason the pass is famous. Many travelers ride it as part of a Da Nang to Hue transfer, with luggage sent ahead by bus. Operators run one-way rentals designed exactly for this.
Private car and driver
The comfortable option and genuinely affordable. A driver for the Da Nang to Hue transfer via the pass, with stops at the summit and viewpoints, costs a fraction of what it would anywhere else. This is the right choice for most people and for anyone carrying luggage.
The Easy Rider option
Ride pillion with an experienced local rider. You get the motorbike experience without riding it yourself, and the guide will stop at the places worth stopping at. A good middle ground.
Train
Underrated. The Da Nang to Hue rail line hugs the coast at points the road does not reach, and it is one of the most scenic short train journeys in Southeast Asia. Cheap, comfortable, about three hours. It doesn't cross the pass itself, but the coastal section is spectacular.
What to stop for
- The summit gate and bunkers — French colonial fortifications later used by American forces. The views on a clear day run the length of both coastlines.
- Lang Co beach and lagoon — on the Hue side, a long sweep of sand and a fishing lagoon. A good lunch stop.
- Elephant Springs (Suoi Voi) — freshwater pools slightly off the route on the Hue side, popular with locals at weekends.
- The viewpoints on the Da Nang ascent — several pull-offs looking back over Da Nang Bay and Son Tra peninsula.
When to go
Morning is best — clearer, cooler, and less traffic. The pass is frequently in cloud in the afternoon, particularly on the Hue side. Avoid the rainy months of October and November when visibility can be poor and the road genuinely slippery.
Da Nang first
Most people ride the pass from Da Nang. Our guide to the city covers where to stay, what to eat and why people extend their stays.
