Standing halfway up the pass, with deep green cliffs on one side and the endless sea stretching out on the other, feeling the throttle vibrate slightly through each curve—that is a sensation anyone who has ever ridden a motorbike over Hai Van Pass will remember forever. But precisely because of those hairpin turns and long slopes, many people ask me: “Is riding a motorbike over Hai Van Pass dangerous?”. The short answer: yes, if you are subjective, and completely safe if you prepare properly. Here is what I’ve learned after many times traveling this route.
So, is Hai Van Pass really dangerous?
The pass is about 20km long, with many sharp turns, steep gradients, and limited visibility at blind curves, and it often has trucks and container trucks running in the same direction. The weather on the pass also changes faster than in the city—sunny skies can turn to fog in just a few minutes, especially the section near the top of the pass in the early morning. These are the factors that make Hai Van Pass classified as a “driving challenge” route.
An important thing to remember: motorbikes are not allowed through the Hai Van Tunnel, and must take the mountain pass road above. Therefore, if you have chosen a motorbike as your means of transport, you have no choice but to prepare carefully to conquer this pass.
Check your bike before departing
Before heading up the pass, spend 10-15 minutes checking that the brakes, tires, lights, and horn are working well. Fill up your gas tank, as there are no gas stations on the pass, and the nearest one to the foot of the pass (Danang side) is located just before the steep section, so don’t be complacent and wait until you’re on the pass to refuel.
Riding techniques for the pass
When going downhill
Shift to a low gear (1st or 2nd) to use engine braking; absolutely do not turn off the engine to coast downhill and do not ride the brakes continuously, which can easily lead to brake failure due to overheating.
When braking
Use both front and rear brakes evenly, avoiding using only one side as it can cause the bike to skid on slopes.
When cornering
Do not take wide turns, as you can easily skid if there is oncoming traffic. Pay attention to the convex mirrors at blind corners, and for trucks and containers, slow down, observe carefully, and proactively yield—these are vehicles that are difficult to avoid suddenly on steep roads. Keep a safe distance from the vehicle in front to react in time if they brake suddenly.
Choosing the right time
The most ideal season to travel Hai Van Pass is from March to August—the weather is dry with little fog and clear visibility. If you want to “hunt clouds,” try to go between 5-6 AM or 3-5 PM. You should avoid the rainy and stormy season (September to December), as the roads are slippery and the risk of landslides increases, especially after heavy rains.
Safe stopping points
Everyone traveling Hai Van Pass wants to stop and take a few photos, but you should only stop at locations with signs or wide shoulders, avoiding stopping in the middle of a curve or hidden sections. The most beautiful and safest stop is Hai Van Quan at the top of the pass, where you can both see the panorama of Da Nang and Lang Co Bay and have a proper parking area.
Hai Van Pass is not a route for the inexperienced or careless, but if you prepare your bike well, use the right techniques, and choose the right season, this will be one of the most memorable motorbike road trip experiences in Central Vietnam.
