Why go

The Hai Van Pass, ‘pass of the ocean clouds’, is one of the most beautiful roads in Vietnam. It climbs from the edge of Da Nang through forest and switchbacks to a saddle almost 500 metres above sea level, then winds down to the fishing village and lagoon of Lang Co. On the way you get views back to Da Nang’s bay and forward to beaches and mountains.

Since a tunnel opened in 2005, most trucks and buses avoid the pass, leaving the old road to motorbikes, cyclists and a few cars. That has made it a classic route for riders, many of whom continue all the way to Hue. If you don’t ride, hire a driver or join a tour with a local rider who knows the road.

At the top, there are the remains of an old fortified gate, Hai Van Quan, along with cafés and souvenir stalls. On a clear day the view is spectacular; on a cloudy day you’ll understand the name, as clouds pour over the ridge from the north.

The story

The pass marks a traditional border. For centuries the mountains here divided the Cham kingdom from the Dai Viet to the north, and later separated regions of the Vietnamese kingdom. Even today, the climate differs on each side: the north is often cooler and wetter, especially in winter.

The fortified gate at the top was built in the early 19th century under Emperor Minh Mang, to control the road between Hue and the south. Its two inscribed gates are weathered but still visible, and during the French period and later wars the site was used as a military outpost, with bunkers that you can still explore.

The pass became famous among foreign travellers after a television programme in 2008 showed it as a stunning coastal road. Since then it has been a must for motorbike adventurers in Vietnam.

Lang Co, at the northern foot, is a fishing village on a sandbar between the sea and the Lap An lagoon. The lagoon is known for oysters and clams, and small restaurants on stilts serve seafood fresh from the water, with the mountains reflected in the still lagoon.

Getting there

From Da Nang, follow the coast road north past Nam O; the pass starts about 20 km from the city centre. Many riders continue to Hue, about 100 km in total.

The North–South train runs along the coast between Da Nang and Hue, passing tunnels and cliffs with views of the sea. It takes around 2.5–3 hours and is a scenic alternative if you don’t ride.

A suggested plan

1. 7:00Leave Da Nang early before traffic and heat.
2. 8:00Stop at viewpoints on the way up.
3. 9:00Hai Van Gate at the summit; coffee with a view.
4. 10:30Descend to Lang Co and the Lap An lagoon.
5. 12:00Seafood lunch by the lagoon; continue to Hue or return.

Where to stay

Start from Da Nang. If you are continuing north, overnight in Hue. Lang Co has beach resorts for a quiet stopover.

Good to know

• Check the weather: fog can make the pass dangerous and remove the views.
• Easy Rider tours offer a safe way to experience the pass on the back of a bike.
• Carry a jacket; it can be cooler at the top.
• Send luggage by car or bus if you ride to Hue.
