Hai Van Pass: Four Ways to Cross It

The Hai Van Pass (Đèo Hải Vân, "Sea Cloud Pass") is the 21 km mountain road climbing from sea level on the Da Nang side to 496 m at the summit and back down to the lagoons north of Hue. Top Gear's 2008 episode put it on the global tourist map, and it has stayed there. On a clear day the views down to Lang Co bay are as good as any coastal road in Asia.

There are four ways to cross. Each suits a different kind of trip.

Option 1: Ride a motorbike yourself

The classic choice for confident riders. The road is well-paved, two lanes each way at the bottom and one lane each way for most of the climb, with switchbacks but no real surprises. There are pullouts at the summit (around the old French and US bunkers) for photos.

What it costs:

• Bike rental — 150,000–400,000 VND/day depending on type. A 110cc auto scooter handles the pass fine in dry weather; for two riders with luggage, a 150cc manual is more comfortable. See motorbike rental.
• Fuel — full tank, 80,000–150,000 VND, plenty for the round trip.
• Helmet, water, sunscreen — bring or buy on the way.

Time: 1.5–2 hours Da Nang to the summit, 3.5–4 hours through to Hue including stops.

One-way bike drop-off: Tigit, Style Motorbikes and several Hoi An / Da Nang rental shops will deliver you a bike in Da Nang and collect it in Hue (or vice versa) for around 300,000–500,000 VND on top of the rental. This is the right setup if you want the ride but don't want to backtrack.

Don't ride the pass if: the weather is wet (mist reduces visibility to metres), you've ridden a motorbike fewer than five times in your life, or you don't have a valid licence and insurance. Read traffic safety first.

Option 2: Easy-rider with luggage transfer

The trip with the most photos taken of you. An "easy-rider" guide rides the bike with you on the back, while your luggage either rides on a second bike or transfers separately by car. Operators include Hoi An Easy Rider, Da Nang Easy Rider and a long list of independent guides.

• Cost — 1.4–2.2m VND per person (around $60–90) for the half-day Da Nang to Hue with stops.
• Includes — guide, bike, helmet, fuel, lunch, photo stops at the marble mountains, Lang Co bay, Elephant Springs (optional), Hue arrival at your hotel.
• Duration — 7–9 hours.

The right choice if you want the bike experience without the responsibility, with a guide who knows the stops and the food places along the way.

Option 3: Private car with driver

The most comfortable option, and the right one if you're with parents, kids or anyone who'd rather see the pass than survive it.

• Cost — 1.4–2m VND for a 4-seat sedan Da Nang to Hue via the pass with 2–3 stops; 2–2.5m VND for a 7-seater. See car with driver for booking detail.
• Duration — 3 hours direct via the tunnel, 5–6 hours over the pass with photo stops.
• Note — many drivers will default to the Hai Van Tunnel (the 6.3 km road tunnel beneath the pass) which saves an hour. Specify in writing that you want the pass, not the tunnel, or you'll discover the difference only when you arrive in Hue with no photos.

Option 4: The coastal train

The single best-kept secret on the route. The Reunification Express line skirts the coast east of the pass, on a separate alignment that doesn't climb to the summit but offers a different and arguably better set of views — directly above the sea, around headlands the road doesn't reach.

• Cost — 100,000–200,000 VND in soft seat, more for sleeper class. See Reunification Express.
• Duration — 2.5–3 hours Da Nang to Hue.
• Best seats — right side going north (Da Nang to Hue), left side going south. The seaside.
• Trains — most of the SE and TN services run this segment. SE19/SE20 and SE3/SE4 are common picks.

The train is the right choice if you don't ride bikes and you've already decided you'll take a private car for another segment of your trip.

Which direction for the views

Most photographers say north to south (Hue to Da Nang) is the better direction for motorbikes — you climb up to the summit with the bay opening in front of you, rather than approaching it from below. For the train, it's the opposite — the coastal stretch looks more dramatic riding into Da Nang from the north. Either works; weather matters more than direction.

When to go

Avoid the wet season afternoons (September–November) when fog rolls onto the pass and visibility drops to nothing. Dry season mornings (February–August) are excellent. The pass closes briefly during severe typhoons but otherwise stays open year-round.

A reasonable combined plan

Best-value setup for most travellers: stay in Hoi An or Da Nang for a few days, ride or be ridden over the pass to Hue with luggage transfer, return to Da Nang on the coastal train two or three days later for the airport. You get the pass, you get the train, you don't ride twice, and you finish at the airport without an extra transfer.
