Hai Van Pass Guide: Motorbike, Train or Tunnel (Da Nang)
Plan the Hai Van Pass from Da Nang: bike, car, train or tunnel, timing, safety, stops and a Hue-to-Hoi An option, with clear trade-offs.
On this page
Last updated November 2026: the Hai Van Pass is about 21 km of National Route A1 that climbs to roughly 496 m between Da Nang and Lang Co. You can ride or drive over it, take the train around the mountain, or go beneath it through the tunnel. From Da Nang, the pass alone fills a half day, and only the old road gives you the views.

Hai Van Pass at a Glance
Hai Van means Ocean Cloud, and the name fits a ridge that often sits in cloud. The old road crosses the Truong Son Range and links Da Nang with Lang Co and Hue. Since the Hai Van Tunnel opened in 2005, most through traffic goes underneath. That leaves the mountain road for riders, tour groups and vehicles that cannot use the tunnel. Fuel tankers are reported to be among them.
- Pass length: about 21 km (13 miles) on National Route A1
- Summit height: about 496 m (1,627 ft)
- Full Hue to Hoi An journey: about 160 km (100 miles)
- Best fit: confident riders, passengers on a guided ride, and anyone with a half day free from Da Nang
Four Ways to Cross the Hai Van Pass
Pick by what you want from the day. Views and flexibility come from the old road. Speed and certainty come from the tunnel. The train hugs the coastline and passes through a number of tunnels, so it suits travellers who want scenery without driving. Check Vietnam Railways for current timetables and fares before you plan around a departure.
| Option | Views | Time | Cost level | Skill needed | Weather dependence |
|---|---|---|---|---|---|
| Motorbike over the pass | Best of all options | Half day or more | Medium to high with a guide | High if self-riding | High: cloud and rain matter |
| Car or taxi over the pass | Very good through the window | About 2 hours round trip with stops | Medium | None | Medium |
| Scenic train | Coastal views from the carriage | Fixed by timetable | Low | None | Low |
| Tunnel | None | Shortest | Low | None | Low |
Best Route and Direction: From Da Nang, Hue to Hoi An, or the Reverse
For a Da Nang base, the simplest plan is a round trip: up the pass, a stop at the summit, then lunch at Lang Co and back the same way. A one-way run from Hue to Hoi An covers about 160 km and ends in Hoi An, so you need a plan for the bike and your bags. Guided tours often move luggage to the final hotel and take the bikes back for you. The reverse direction works if you start in Hoi An or Da Nang. Either way, arrange one-way drop-off before you leave, and keep a rented bike off the pass unless the return point is agreed.
How Much Time to Plan
Reported timings vary with how often you stop. A Da Nang round trip with photo stops took about 2 hours. A full Hue-to-Hoi An day took over 8 hours door to door, against about 3 hours of riding with no breaks. Treat these as ranges, then add time for the summit and a long lunch.
| Plan | Rough time | What it covers |
|---|---|---|
| Pass only from Da Nang | About 2 hours round trip, more with stops | Climb, summit, descent and return |
| Pass plus Lang Co | Half to most of a day | Adds lagoon, beach and a seafood lunch |
| Hue to Hoi An | 3 hours riding, over 8 hours door to door | Countryside, Lang Co, pass, Da Nang and the road south |
When to Go and How to Read the Weather
The summit sits on a ridge, so weather there can differ sharply from the coast. Da Nang may be clear while the top is wrapped in cloud. Look at the ridge from the city in the morning. If the summit is hidden and rain is forecast, move the ride to another day or take the train. Before you set off, check the forecast and road-work notices through the Da Nang tourism site. Go early to beat tour groups at the top.
Safety, Licences and Rental Tips
Trucks and buses overtake on blind corners, and goats and cows wander onto the road. Ride defensively and keep your speed low on the hairpins. Never rent a motorbike for the pass if you have not ridden before. A guided ride with a rider handling the bike is the safer way to see the views. If you do ride, carry a valid licence and check what your rental insurance covers. Wear a helmet and photograph the bike's condition at pickup. Rip currents are common on this coast, so swim only where locals do.
What to See: Summit, Lang Co, Elephant Springs and Other Stops
Summit: bunkers and an old fort stand near a former gate, with food and coffee stalls beside the road. A Nguyen-dynasty gate dates to 1826. Expect crowds at peak times. Lang Co Beach and lagoon: stilt restaurants line a narrow spit between sea and lagoon. Good for lunch and photos, not for casual swimming. Elephant Springs: a mixed stop. It suits hot-weather riders who want a plunge pool, and it comes with a leech warning. Fishing villages on the Hue side matter only if you ride the through-route.
Clouds at the summit, about 496 m up, can hide the view while Da Nang stays clear.
- Summit: bunkers, old fort, coffee stalls, parking along the road
- Lang Co: lagoon-side seafood, bridge views, rip currents offshore
- Elephant Springs: plunge pool, boardwalks, leeches possible
- Hue-side villages: rice paddies and fishing lakes, through-route only
Costs, Fuel and Parking
Prices change, and no current fare is listed here. Anchor your budget by level. The tunnel and train cost least, a taxi or car costs more, and a guided motorbike day with luggage transfer costs most. One 2018 traveller report put Elephant Springs motorbike parking at ₫2,000. Fuel up at a proper station in Da Nang or Hue, not from roadside bottles. Park at the summit only where other vehicles are already parked, and keep valuables with you. Plan lunch at Lang Co if you start from the Hue side. From Da Nang, eat after you return or pack snacks.

Combine With Other Da Nang Sights
The pass pairs best with a short stop rather than a second big outing. Linh Ung Pagoda Da Nang: Which of the 3 to Visit sits on the Son Tra side of the city and fits an afternoon after a morning ride. Marble Mountains Da Nang Guide: Gates, Costs & Timing lie on the road south toward Hoi An, which makes them a natural last stop on a Hue-to-Hoi An day. Give Ba Na Hills Guide: Is It Worth It, Tickets & Getting There its own day. Find more options in our Da Nang day trips guide.
Common Mistakes to Avoid
Most problems come from timing and overconfidence. Start late and you reach the summit in cloud with no view. Skip the forecast and you ride into rain on wet hairpins. Rent a bike with no experience and you take on trucks on blind corners. Swim at Lang Co without checking the surf and you risk a rip current.
Starting late on a Hue-to-Hoi An day leaves little slack, as one reported run took over 8 hours door to door.
- Starting late and meeting tour-group crowds at the summit
- Riding without a licence, insurance or a helmet
- Buying fuel from roadside bottles
- Leaving luggage plans and one-way drop-off until the last minute
Frequently Asked Questions
Is Hai Van Pass worth visiting?
Yes, if the summit is clear and you pick a way to cross that suits your comfort level. The old road gives the coastal views that the tunnel skips. Choose the train or a car if you do not want to ride.
