The Hai Van Pass winds 21km along the Truong Son range as it plunges into the sea, forming the natural border between Da Nang and Thua Thien Hue. King Le Thanh Tong once bestowed upon it the title "Thien ha de nhat hung quan" — the grandest pass under heaven. Top Gear once called it one of the world's most beautiful coastal roads.
Why "The Grandest Pass Under Heaven"?
The summit sits nearly 500m above sea level, with a sheer cliff on one side and deep blue ocean on the other. Clouds often drape across the midsection of the pass — which is exactly why it is named "Hai Van" (sea and clouds). At the top stands the Hai Van Quan gate, a recently restored Nguyen-era fortification offering sweeping views over Da Nang Bay and Lang Co Bay.
Photo Stops You Can't Miss
- Hai Van Quan: The ancient stone gate at the summit, with stunning 360-degree views. Stop for at least 20-30 minutes.
- The hairpin bends: Several small roadside pullouts overlook the sea and the winding road below.
- Lang Co Bay: On the Hue side, a long crescent beach and a peaceful fishing village — an ideal seafood stop.
Pass or Tunnel? A Quick Comparison
The Hai Van Tunnel is 6.28km long and takes about 10-15 minutes — safe and fast, but with no scenery. The pass road is longer (~21km, 45-60 minutes) but gives you the full scenic experience. Our advice: take the pass when it's bright and dry for the views, and use the tunnel after dark or in heavy rain for safety.
Staying Safe Over the Pass
As beautiful as the road is, it demands confident driving. A local driver knows every bend, the safe pullouts, and when fog rolls in — letting you enjoy the scenery instead of gripping the wheel. That's why many travelers choose a car with a driver for the Da Nang - Hue leg.
Standing at Hai Van Quan, looking down on two bays cradled in a single view, I finally understood why the ancients called this the grandest pass.
FAQ
How long does the Hai Van Pass take from Da Nang?
Reaching Hai Van Quan from central Da Nang takes about 40-50 minutes. Driving the full pass to Lang Co (Hue) adds another 30-40 minutes depending on your stops.
Is the pass dangerous?
The road has many sharp bends and sudden fog, so it needs confident driving. A driver who knows the road, or going very slowly on a dry early morning, is safest.
Should I drive the pass at night?
No. At night it's poorly lit, fog is thick, and there's no scenery — use the Hai Van Tunnel instead for speed and safety.
